Two-Stage Cyclone Dust Collectors

Cyclone dust collectors have a number of advantages over ordinary dust collectors. The primary advantage is their ability to remove most of the chips and dust particles from the air stream before it reaches the filter. This is accomplished by the conical shape of the collector body creating a centrifugal force that separates the dust and chips into the collection drum below. After this happens, the clean air stream continues up the center of the collector through the impeller and filter. The drum can be easily emptied without lengthy down time as a result of having to remove blower housings and emptying filter bags.

The secondary filter collection point captures 99.9% of the very finest dust down to 0.2 microns. Since the same volume of air entering the dust collector must also exit the dust collector through the filter, our filters are pleated to maximize surface area and efficiency. Dust cake on the filter also diminishes the amount of air volume that can enter the system and reduces the performance of the dust collector. Our cyclones have a patented mechanical brush system that gently brushes the cake from the filter and into a plastic collection bag for nearly continuous maximum filter performance.

With all these things considered, cyclone dust collectors are the best way to go!

There are three critically important performance criteria for cyclones. First is the filtering ability of the filters. Second is the amount of material the cyclone will remove from the air before reaching the filters. Third is the ability of the cyclone to effectively move a high volume of air.

The “performance curve” shown here is a way to visibly see the real world performance of a dust collector. The row on the bottom is Static Pressure (think suction). The column on the left of the graph is the amount of air being moved, measured in CFM (Cubic Feet per Minute). *Note: The common unit for measuring static pressure is inH20 or “inches of water.” This dates back to the way pressure was first measured using a U-shaped tube partially filled with water. If you were to lightly blow into one side of the tube, the water will rise on

the other side, proportional to the pressure with which you blow. The distance the water rises in inches is the pressure in inH20. Modern measurements are made with precision instruments, not U-shaped tubes of water, but the unit of measure remains the same.

Two-Stage Cyclone Dust Collectors

So, just how important is static pressure? Well, first let‘s clear a little myth that has been going around for years. Dust collectors are NOT vacuums. Vacuums have very high static pressure, and we’ve all seen the ads of the vacuum that can pick up a bowling ball. Try that with a dust collector and you had better be wearing steel toed shoes. But in that sense, you can kind of think of static pressure as how much “vacuum” or “suction” something has. However, dust collectors work differently than a vacuum. By moving LOTS of air at a fairly high speed, the wood chips are carried in suspension through the duct work in the same manner as they would be blown around with a fan. If the air is moving too slow, the dust will fall out of suspension and start piling up in elbows or even in straight pipe. So, compared to a vacuum that moves a small amount of air under very high static pressure, a dust collector will move huge amounts of air at much lower static pressure. Even to this day, we get calls from customers who bought one of our dust collectors and then plumbed their entire house, thinking they would use it as a central vacuum and “save a bundle.” Needless to say, they did not get the desired result.

When a restriction is placed upon the cyclone, such as connecting to a smaller diameter dust port or multiple lengths of pipe, the static pressure will go up while the CFM goes down. And CFM is what we really need to keep the dust in suspension. Many cyclones and dust collectors have a very good CFM reading without any restrictions, but as soon as restrictions are applied the CFM drops dramatically. Said another way, they work great until you try to use them with a system of elbows, blast gates, dust ports and lengths of pipe, then they suffer. Other things that can affect the static pressure reading during a test are barometric pressure, temperature and humidity. The same cyclone system measured the same way, but on different days with different atmospheric conditions will have a slightly different reading. This is one reason why numbers are seldom the same between two testers.

To measure the CFM, a pipe is connected to the cyclone (a minimum of 10 times the pipe diameter in length) and a small L-shaped instrument called a pitot tube is inserted into the pipe with the opening of the pitot tube facing into the incoming air. The force of the moving air creates a positive pressure on the

end of the pitot tube which is called the “velocity pressure.” By measuring the velocity, static pressure, and the pipe diameter, the CFM can be calculated using a universally accepted formula.

Performance CurveTo evaluate and compare the performance of dust collectors, a series of measurements are taken of the CFM and static pressure. The first measurement is taken wide open with no restrictions at all. Subsequent readings are made as the opening of the test pipe is slowly blocked off. There are several ways of doing this. One is to use a series of “restrictor plates,” which are basically wooden tiles with holes in them (i.e. 6”, 5”, 4”, etc). The plate is placed over the end of the pipe and the measurement taken. This is repeated all the way down to zero where the opening is fully closed. At this point the CFM will be zero and the static pressure will be at its maximum. This data is plotted on a graph with CFM on one axis and static pressure on the other. This type of graph shows how a specific dust collector will perform in the real world as it is restricted down with ductwork and multiple machines. Generally speaking, the higher the maximum CFM, the more machines you can run simultaneously; and the higher the maximum static pressure, the larger and more elaborate the ductwork system can be.

Comparative performance testing on 5 HP units

Testing and DevelopmentAfter two plus years of research and development, we released our first batch of Cyclone Dust Collectors. We had a long list of design and performance criteria and after countless hours we were finally satisfied with what we had created. Our 1.5, 2, 3 & 5 HP models were well received but we continued to make subtle improvements like our noise reducing mufflers that do not reduce airflow and our plastic drum liner bag system that makes emptying a breeze. To keep up with the demands of the market, in 2007 we unleashed our 7.5 & 10 HP Cyclones. These beasts maintain all of the important features of our smaller models but with larger capacity to meet the needs of larger industrial shops. Every aspect of these machines was put to the test and we did not stop until we had the results we wanted.

ResultsCYCLONEThe most important part of the cyclone system is, of course, the cyclone itself. And we made ours from 25% heavier gauge steel than some of our competitor's, then we powder coated it for a good looking and durable finish. But that doesn’t make a great cyclone, performance does. We spent more than two years developing this design and believe it to be second-to-none in performance. Many factors affect how well a cyclone separates the dust from the air: diameter, height, the angle of the tapered bottom, size and shape of the inlet and outlet as well as internal structure. There has been a great emphasis on cyclones the last few years, and many things have been learned about what makes them work better. We are the only manufacturer to use this latest technology. The inside of our cyclone is not just a round barrel like others, but includes features not found elsewhere. The enemy of a cyclone is turbulence and we have gone to great lengths to reduce it. We use an internal “air ramp” that helps prevent new air that is being drawn into the cyclone from creating turbulence in the air already circling. It also aids in stabilizing the airflow thereby further reducing turbulence and increasing performance. We tested many different designs, and the use of an air ramp outperformed them all. We have a patent application for our design.

Recently, competitors state their design features a "neutral vane" making theirs better. A neutral vane is simply inserting the inlet pipe partially into the cyclone rather than stopping as it meets the cyclone wall. This technology has been used for years while our air ramp represents the latest in engineering and is clearly an improvement over this older technology as well as being more expensive to build.

Our reinforced inlet is notably as well as visibly different and specifically engineered to enhance performance. The round inlet is transformed into a rectangle before entering the

cyclone, which provides a much better flow of air against the cyclone walls when compared to a round inlet regardless of its internal length. A further look will reveal that our inlet does not enter the cyclone at a 90° angle like others do. Careful studies and much experimentation have shown us what angle would achieve the highest level of performance. This angle is precisely matched to the natural flow inside the cyclone, effectively starting the cyclonic action earlier in the process. This along with the extra length of the inlet greatly reduces turbulence, thereby maximizing performance and efficiency.

The body of our cyclone rotates in 30° increments to allow positioning the inlet right where you need it.

The bottom tapered half of the cyclone design is also critical. We experimented with dozens of lengths and outlets until we arrived at what worked best with our upper design.

FILTEROne of the most important components to a cyclone dust collector, besides the cyclone, is the filter. Our filters are BIA certified and are manufactured in Europe by one of the most respected filter manufacturers in the world. These filters offer very fine filtering ability using only the best non-woven polyester material available. They are certified to trap 99.9% of particles from 0.2 to 2.0 microns, under normal operating pressure. The pleated filters on the G0443 11⁄2 HP & G0440 2 HP have 96 ft2 of filtering area, the G0441 has 113 ft2, the G0442 and G0601 5 HP have 226 ft2, the G0637 71⁄2 HP has 260 ft2, and the G0638 10 HP has a whopping 390 ft2 of filtering area.

Our patent-pending cleaning system ensures optimum performance and long filter life. Inside the filter is a soft brush, which cannot damage the filter as it gently sweeps the dust off the filters from top to bottom with a simple pull of the handle. There are no rubber paddles or anything else that will damage the filter or cause wear. Our exclusive design allows the filter to last many times longer than one cleaned with compressed air or rubber paddles. You can safely and completely clean

the filter as often as you like without worrying about damage to the filter. Any dust coating the inside of the filter is swept into the bag for easy disposal. As a matter of fact, we strongly recommend you not clean with compressed air as this has been proven to reduce the life of the filter as well as blow the very finest and most hazardous particles of dust throughout your shop.

Our clear filter bag offers distinct advantages over what others use as well. You will quickly learn how often to clean the filters by seeing how much dust falls into a clean bag and without disassembling anything. The bag makes for simple cleaning and since it seldom needs emptying, most people will opt for just tying the bag shut and throwing the whole thing away instead of dumping it out. And finally, one advantage that our two years of design and testing showed is that it allows you to see how full it is. Why is that important? Well, sooner or later you may be planing a lot of lumber, or forget to empty the collection drum or even “just plane these last couple boards before emptying the drum” and it will overfill. What happens is that all the sawdust will back-up inside the cyclone then pass through the cyclone and into the filter. Before you know it, this will create at the very least a dusty mess, and with other brands, can actually damage the impeller (but not ours). A quick glance from across the room will tell you if anything is passing through the cyclone.

Our filter is protected within a steel cage from the “bumps and bruises” that can happen when carrying lumber around or just working in your shop. It may seem like a small thing, and perhaps it is. And that’s exactly why we can’t understand why everyone doesn’t do it. Filters are expensive, cannot be repaired, and must be replaced if damaged, so a little “insurance” can prevent an unneeded and unwanted expense.

See pages 8 & 9 for more features to our cylones.

WALL MOUNTINGWe knew we wanted to allow our customers a way to mount the cyclone to a wall, existing structure or even a home-made stand, so we made the impeller-housing square and added mounting holes. This allows easy mounting with-out any additional purchase. However, before mounting to a wall consider that the noise generated by the cyclone will be greatly amplified on the other side of the wall when compared to using a stand.

Which Cyclone is Right For You?Woodworking machines require a minimum CFM of airflow in order for chips and dust to be carried away from the machine. This minimum airflow varies depending upon type and size of machine. A good rule of thumb is roughly 300-400 CFM per machine for smaller capacity home shop sized machines and 400-800 CFM for larger capacity industrial sized machines.

Static pressure is a measurement that correlates to the dust collector's ability to maintain airflow through long and less efficient duct systems. In other words, the higher the static pressure rating for a dust collector, the more complex duct system the dust collector will handle. Please refer to additional information sources about duct design and static pressure.

Please refer to the specifications for each cyclone in the back of this brochure for any other considerations related to your shop.We offer a wide selection of cyclones designed for use in home

sized shops up to commercial sized operations. Since every shop is different, each shop owner must decide which cyclone is right for their particular needs and limitations.

When deciding which cyclone is right for you, consider how many woodworking machines will be in use at one time, the length and relative efficiency of your duct system, and the physical limitations of your shop such as ceiling height, power supply and available floor space. Even though we keep our prices as low as possible, cost is also a big consideration, especially when adding up all the parts for a duct system. Blast gates allow you to add more machines to a duct system, yet isolate them from the cyclone when not in use. This allows you to maximize the power of your cyclone over more woodworking machines, but requires you to open and close blast gates to direct airflow depending on which machine or machines are in use at any given time.

INLETAn internal “air ramp” helps prevent new air being drawn into the cyclone from creating turbulence, thereby stabilizing the airflow and increasing performance. We tested many different designs, and the use of an air ramp outperformed them all. We have a patent application on our design.Our reinforced inlet is notably different and specifically engineered to enhance performance. The round inlet is transformed into a rectangle before entering the cyclone, which provides a much better flow of air against the cyclone walls when compared to a round inlet, regardless of its internal length. A further look will reveal that our inlet does not enter the cyclone at a 90° angle like others do. Careful studies and much experimentation have shown us what angle achieves the highest level of performance. This angle is precisely matched to the natural flow inside the cyclone, effectively starting the cyclonic action earlier in the process. This along with the extra length of the inlet greatly reduces turbulence, thereby maximizing performance and efficiency.

STANDOur 14 gauge heavy-duty steel stands are designed in two pieces to keep the entire package smaller, which saves you money in shipping. The stand is supplied at no charge on the 5 HP and above cyclones, and is optional on the others. The H7509 stand for the G0441 is adjustable for height if you need your 3 HP to fit under an 8’ ceiling.

COLLECTION DRUMOur drums are supplied with the cyclone and are made from steel then powder coated for a lasting durable finish. These drums will outlast fiber drums many times over.We added simple quick release latches instead of the sometimes difficult to use wrap-around type barrel clamps to secure the top. A drum full of sawdust is heavy and awkward to handle. If you have ever tried to slide a drum full of sawdust across a floor, you know what we mean. Casters, securely mounted to the drum bottom, make the drum easy to move.We use a two-piece steel drum on all models 3 HP an up. Why two-piece? You can choose to use only the bottom portion if your ceiling height is limited. Of course, the collection capacity is reduced; however, the cyclone performance remains the same.OPTIONAL BAG HOLDERSWe also offer bag holders that make emptying the drums easier.55 gallon bag holders are standard on G0637 & G0638.35 gallon & 55 gallon bag holders are optional on all other models.H8173 35 gallon bag holderH8174 55 gallon bag holder

PACKAGING In addition to all of the performance based criteria we applied to our cyclone design, we kept in mind that they must be shipped to our customers. To keep shipping costs down, we designed many components so they could be collapsed down for easy shipping, and packaged them so they could be transported as safely as possible. What good is a Cyclone if it shows up to your door damaged?

MOTOR MOUNTOur motor bolts to a supported steel plate that attaches to the blower housing. This extra steel helps reduce noise caused by the impeller, provides a more rigid mount and makes for a convenient lifting bracket.

SWITCHGrizzly has always believed in the benefits of using a magnetic switch with thermal overload protection. We knew we wanted to use them on our cyclones, but that presented us with an unusual problem. Our customers appreciate having a remote control and a programmable timer. Rather than settle for “almost” we put the engineers to work and designed a patent pending remote controlled magnetic switch with a programmable timer. The cyclone can be turned on or off from anywhere in your shop, as well as the timer set for 2, 4 or 8 hours.

Others charge hundreds of dollars for an optional magnetic switch or charge extra for a remote. We are the only manufacturer to combine both and supply them as standard equipment!

BLOWER HOUSINGAs we were designing our blower housing, we wanted it to be dual purpose so we made it square and included mounting “keyholes.” This allows mounting to a wall or structure much easier if you choose not to purchase the optional stand. (All our 5 HP and larger cyclones come with the stand at no additional charge.) We wanted it to be strong, so we used 11 gauge steel that’s up to 2 times thicker than our competitors, fully welded on both sides (no spot welds here) then powder coat it for a durable and good looking finish.

Frequently Asked QuestionsQ. What is a cyclone dust collector?A. A cyclone dust collector is similar to a regular dust

collector except it separates the wood dust and chips from the air and deposits them in a separate drum for easy cleaning. Some refer to cyclones as 2-stage, but that term is a little too broad and does not describe accurately what it is. Depending upon the manufacturer and their design goals, cyclones can also do a tremendous job of filtering the fine dust particles that are often blown into the air by a regular dust collection system.

Q. How does it work?A. Cyclones have been around longer than many of us

have been alive, and do not represent new technology. They have been used in industrial applications and for agriculture for decades. It has only been in the last several years that smaller shops and homeowners have begun taking a serious look at using cyclones. Their operation is actually quite simple. The air enters the cyclone and spins around in a circle, forcing the dust particles to the outside. Here the air pressure is somewhat reduced and causes the dust to travel down the wall of the cyclone. The air continues to spin as it too moves down the cyclone. When entering the tapered portion of the cyclone, the air and dust particles must rotate in a smaller and smaller circle which further separates out the fine dust, forcing it to the outside were it continues to slide down towards the collection drum. Our cyclone does an excellent job of separating the fine dust out of the air by reducing turbulence inside the cyclone. Turbulence inside the cyclone “stirs-up” the air which keeps those fine dust particles in suspension rather than dropping out of the air. A properly designed cyclone will separate nearly all the coarse and fine dust from the air, allowing very little to pass through the cyclone into the filter. Turbulence inside the cyclone is its worst enemy. Our design significantly reduces turbulence, thereby increasing performance.

Q. Why would I want to spend the extra money on a cyclone over a regular dust collector?

A. The two big reasons to purchase a cyclone over a regular dust collector would be convenience and health. Emptying the caster equipped drum is far more convenient then removing and reinstalling a bag on a regular dust collector (and faster, too). Some will opt for having multiple drums, so the full one can be rolled to

the side and immediately an empty one can be rolled into position, without a lot of down time. As for health benefits, the extremely fine filtering capability makes sure the hazardous small particle dust is removed from the air in your shop. With that said though, it would be unwise to ignore established safety precautions and respirators should still be worn.

Q. Why is the CFM less with a cyclone than a regular dust collector of the same HP?

A. The cyclone itself adds restrictions to the amount of air moved by the impeller. Said another way, the cyclone has the same effect on performance as adding additional lengths of duct work. You see, the air travels around the inside of the cyclone many times before exiting to the filter. Plus just the fact there are pressure reductions when entering the cyclone adds a restriction. If the cyclone was just a round cylinder with a pipe in and out, that alone would induce restrictions. Just as a 2-stage dust collector will have reduced CFM because of this, the same holds true for a cyclone. Something to keep in mind though, is a cyclone's CFM will remain constant, regardless of how full the barrel is. The CFM of a regular dust collector will start to drop from the moment it is turned on and used. A regular dust collector with full bags can have a 30% or more reduction in performance.

Q. What is Static Pressure?A. Static pressure (SP) is the difference in air pressure

between the air inside the duct and the air outside the duct. The result is the suction that allows the dust collection or vacuum system to pick up chips and dust. If you take your hand and move it slowly towards the opening of a vacuum cleaner hose, the hose will pull harder and harder at your hand as it gets closer. When your hand completely covers the opening, the static pressure is at its maximum. At this point the airflow (CFM) goes to zero. Static pressure is not suction, but it is what causes suction. The higher the rated static pressure = the higher the suction potential. So for a simple, brief definition: static pressure is the amount of suction potential that a dust collector (or shop vac, or vacuum cleaner, etc.) has. It is worth mentioning that CFM goes down as the static pressure goes up. A good dust collection system will have enough static pressure or suction to pick up the largest chips produced and still have high enough CFM or airflow to keep them moving

Page 11: Cyclone Dust Collectors

11

Two-Stage Cyclone Dust Collectors

through elbows, vertical sections, etc. This is why a chart showing the CFM vs. SP is useful when designing a ductwork system. If you know how much CFM you have at a given static pressure, you can determine if a certain configuration will work or not.

Q. Are they easy to empty?A. Our drums are sealed by three quick release latches

instead of the wrap around barrel type clamps. To disconnect from the cyclone for emptying, simply flip the three latches. Since the drum is equipped with casters, just wheel the drum from underneath the cyclone for easy disposal. The lid of the drum remains attached to the cyclone by the flexible hose. Also, the use of an optional bag holder (standard on 7.5 and 10 HP models) allows you to remove a plastic collection bag inside the drum, making emptying the drums even easier.

Q. Are the filters easily damaged?A. Under normal conditions, the filters are not easily

damaged, but accidents happen. Normally, being hit by a board or some other object will likely cause permanent and irreparable damage to a filter. This is why we protect ours within a steel wire cage. Ours is far less likely to be damaged than one without protection. Another way to damage a filter is by cleaning it with compressed air, which is why we developed a damage-free cleaning system.

Q. Just how well do they separate the dust from the air?A. Our cyclones will remove 99.9% of the particles between

0.2 and 2.0 microns. Larger particles are for all intents and purposes 100% removed.

Q. Are there maintenance costs?A. About the only maintenance cost would be the plastic

drum and filter bags. These plastic bags may be emptied and reused several times before being replaced, or used once and thrown away with the dust and chips sealed cleanly inside. The same is true for the clear plastic bag on the filter bottom, which may be reused or thrown away with the dust that will eventually collect in the bag over a period of time. Because such very little dust passes through the cyclone, it takes quite some time to fill the bag. Thanks to our patented filter cleaning system, the

cost of ownership will be less with our system versus one without a non-damaging filter cleaning system. The actual filter represents a surprising portion of the cost of the cyclone system and that is why we go to great lengths to prevent damage and extend the life of the filter. Our filters should last many years, even under heavy use.

Q. How do I know when the collection drum is full?A. The collection drum needs to be periodically checked

to avoid overfilling it. How quickly the drum will fill is dependent upon the type of work being done at that time. While running a machine that produces more fine dust like a sander or saw, it will take a long time to fill the drum. On the other hand, when planing soft lumber that produces curly shavings, the drum may fill quite quickly. In the beginning, you will need to check your drum regularly until you learn how often it needs to be emptied.

Q. How long will the air filters last?A. This is where our patented cleaning system pays off with

big savings for the owner. Many cyclone manufacturers' filters must be cleaned by blowing down with compressed air. Others use rubber paddles “slapping” the dust off the inside of the filter. The use of compressed air not only blows fine dust throughout your shop, but is also damaging to the filter. Those who do not have our patented cleaning system argue that compressed air does not damage the filter nor does it create dust, but in our testing we found it did in fact damage the filter as well as create a dust cloud. Those same people who say compressed air won’t damage the filter state in their instructions “Closer blasts may damage the filter.” They say it won’t damage the filter, then warn you it may, which is at best confusing. That is why we developed this cleaning system in the first place. The rubber paddles, while better than compressed air, are also hard on the filter. With all that said, our filters will last for years and certainly last longer than those cleaned with compressed air or rubber paddles.

Frequently Asked Questions

Two-Stage Cyclone Dust Collectors

Frequently Asked QuestionsQ. Do the filters plug up and do you have to clean

them?A. Yes, the filters will become clogged with fine dust and

must be periodically cleaned as mentioned above. Our patented cleaning system gently brushes away any built up dust on the inside of the filter, which then falls into the filter bag.

Q. Why do your cyclones look different than others?A. The most notable difference with ours, besides our

square blower housing, is our patent pending exclusive inlet design. It is longer, starts out round, then transitions into a rectangle and meets the cyclone at an angle. All of which improve performance.

Q. Do you really have a remote controlled magnetic switch? I have never seen one offered by anyone else.

A. Yes, we really do have a remote controlled magnetic switch with a built in programmable timer. When we discovered none were readily available, we put the engineers to work and designed one specifically for our purpose. Patent pending.

Q. Other cyclone manufactures say you use a cheap Asian made motor that will not last very long, is that true?

A. We cannot comment on why another manufacturer would make that claim, but maybe it’s their attempt at explaining why their systems cost so much more than ours. Yes, we do use a motor made in Taiwan from the same manufacturer that builds most of our machinery motors. We buy tens of thousands of motors every year from this motor factory and are very confident in the quality. They are one of the highest quality manufacturers in Taiwan, using state of the art equipment. Further, our motors have been specifically designed for continuous, high torque use and are not an off-the-shelf product. We are not saying our motors are better than those made in the USA, but we are saying they are certainly comparable, designed for our cyclones and have additional features such as aluminum cooling fins.

Q. Others say your filters are an inferior quality to theirs, is that true?

A. Our filter material is made by a highly respected European

manufacturer and is BIA certified. In other words, that is not true and the BIA certification proves it.

Q. I already have a dust collector and duct work, but I would like to upgrade to one of your cyclones. Can I use my existing duct work?

A. Probably, but the design and layout of your duct work greatly affects how well it will perform. Long runs, long sections of flex hose or many elbows add restriction. Also it depends on the size of your main line and if it will allow enough airflow to maintain performance of the cyclone collector. To expect proper and efficient performance of the cyclone, you have to maintain a certain amount of airflow through it. If you have a 4” or smaller mainline, you may need to upgrade the size to the same or at least as close as possible to the inlet diameter of the cyclone or add additional trunk lines. Also, when using smaller machines with 2”, 3” or 4” connections, it is a good idea to have a blast gate connected upstream of that smaller connection partially opened to ensure proper airflow to the cyclone.

Q. What’s the difference between cyclones and two-stage dust collectors?

A. All cyclones are two-stage dust collectors, but not all two-stage dust collectors are cyclones. Both drop out heavier dust particles into a drum before passing finer particles through the fan and into a filter, but a cyclone is much more efficient at separating out more of the finer dust into the drum. Our cyclone filters are also pleated for efficient air exchange and are non-woven polyester fabric to capture the very finest dust. Many standard two-stage dust collectors only have bag filters that must be shaken out when they fill up.

Q. Can I use a standard garbage bag in the drum or under the filter instead of buying replacement bags from you?

A. We strongly recommend that you buy the replacement bags from us. Despite each manufacturer’s claims of strength for holding garbage, standard garbage bags do not have the strength to withstand the air pressure produced by the cyclone fan and could blow apart, resulting in very fine dust being released into the air. Our replacement bags are inexpensive and are designed to withstand the high air pressure produced by the cyclone fan.

Q. How difficult is it to set up one of your cyclones?

Q. Others make a big deal out of their cyclones being galvanized. Are yours galvanized?

A. No, and here’s why: First, galvanizing does not add much cost to a cyclone, but thicker steel does. We choose to use thicker steel. Also, we use continuous welds in nearly all our seams. That’s a lot of welding. Galvanizing doesn’t weld very well and tends to burn off near the weld. Our thought was, it’s either fully galvanized or it isn’t, and once welded it’s not. Rather than use galvanized steel that makes welding more difficult, we simply used thicker steel with all its advantages. Finally, our thoughts were that the abrasive action of the debris swirling inside the cyclone will wear away the galvanizing long before rust becomes a consideration.

A. Our cyclones come with complete owner’s manuals and set up is not difficult. With only 4 major components, assembly time is relatively short. Most of the sub-assembly has already been done at the factory and the major components are only broken down for shipping. The optional stands will require additional assembly time. Each cyclone comes complete with fasteners and clamps; however, bolts for mounting the cyclone to the wall, if desired, are not included.

Q. How difficult is it to wire one of your cyclones in my shop?

A. First of all, you must ensure your shop has a spare circuit or the capacity in your service panel to add a circuit that is capable of handling the amp requirements of the cyclone. We strongly recommend you hire a licensed electrician if adding a new circuit. Once the circuit requirements have been met, the cyclone can be hard wired to a wall mounted disconnect or connected to a plug-in device that is controlled by a well mounted disconnect. Each cyclone comes with a 10’ power cord, but since there are so many different types of outlets available, you must purchase a plug end that matches your outlet. Ensure that the amp rating of the outlet device and plug you use also match the amps for the circuit. The G0443 1-1/2 HP Cyclone comes with a 110 plug, and can simply be plugged into a proper receptacle and circuit.

Q. Do I have to buy the stand?A. No, our cyclone is designed to mount to a wall, existing

structure or a stand of your own making. Just make sure whatever you mount it to can support the weight. And for those working in a basement or attached garage, remember that wall mounting may transmit noise into the house. G0440, G0443 and G0441 only. Stand included on others.

Q. Are your cyclones dual voltage?A. The G0443 1-1/2 HP cyclone is 110V/220V, pre-wired to

110V. However, since the magnetic switch and remote control are single voltage, you must purchase a 220V kit to convert it. The model for that is H7498. The G0440 2 HP, G0441 3 HP and G0442 5 HP are all 220V only. The G0601 5HP is 220V 3-phase only. The G0637 7-1/2 HP and G0638 10 HP are 220/440V, pre-wired to 220V. The 440V conversion kit for the G0637 is P0637119, and the 440V conversion kit for the G0638 is P0638119.

STEP ONE: Shop LayoutThe first consideration is the limitation of the workshop space. (Ceiling height, obstructions, electrical service, etc...) For best results place the machines requiring the largest cubic feet per minute (CFM) of airflow closest to the dust collector. The required CFM for each machine may be available in your owner’s manual. If not, measure the diameter of the dust ports on the machine and use the chart below to estimate the CFM requirements. For example, if a machine has a 3" diameter dust port it requires approximately 220 CFM. If a machine has multiple dust ports, the total CFM required is the sum of all ports.

STEP TWO: Draw A Sketch (To Scale) Of Your Machine & Dust Collector Layout.Using grid paper makes this job more accurate. Be sure to indicate the exact location and diameter of each dust port.

STEP THREE: Determine The Total CFM Requirement of Your Shop.Add the CFM requirements for all machine dust ports. The total CFM requirement for the entire shop may exceed the capacity for the dust collector. If that’s the case, blast gates will allow machines not in use to be isolated from the dust system by closing the appropriate blast gate.

STEP FOUR: On Your Drawing, Sketch Out The Position of Your Main Duct Line.Be sure to run the ducting so that it ends directly above each dust port.

STEP FIVE: Determine The Necessary Duct Size. Begin at the machine farthest away from the dust collector and work back towards the dust collector. Determine the appropriate diameter of duct from the CFM requirements at the first machine. (Example, if the machine has a total air volume of 395 then 4" ducting will be required.) Continue on to the second machine. If machine number two has a dust port that is 3" where it connects to the main duct (the 4" duct from machine number one) add the CFM from the above chart. (395 + 220 = 615 or 5" duct). Size the branch as a 5-3-4, with 5" being the largest reducing to 4" with a 3" branch going out the side at 30 degrees. Keep in mind that it will require a 60 degree elbow to keep the run perpendicular. (Note: Machine requirements will not match the chart above exactly. When this occurs, select the pipe size that is closest to the required diameter.) Continue on to the remaining machines (per the example above) adding blast gates where required until your trunk is equivalent in diameter to the size of the collector inlet. For example, consider a system where the main trunk line is 5" in diameter (representing 615 CFM). When connecting to a machine that requires 395 CFM (4" diameter) you would normally add 615 + 395 = 1010 (requiring a 7" duct). However, if the machine can be isolated with a blast gate, the two air volumes would not need to be added together, allowing the existing 5" trunk line to suffice.
