Guidelines for CalculatingAir-to-Cloth RatiosOperating experience is unquestionably the best reference for determining air-to-cloth ratios (A.C.R.). However, the informationbelow may be used as guidelines:

A.C.R. = Materialx Processx Particle Size/Temperature

Step 1To determine the Material Factor, find your material and select the appropriate valuefrom the Material Factor Table. (Table A, top right.)

Step 2Material Loading is expressed in grains per cubic foot.

The Process Factor is a function of the inlet grain loading and type of process. Firstdetermine the material loading which is expressed in grains per cubic foot (gr/cf).

To calculate gr/cf from lbs/min,Multiply: 7,000 gr/lb x lb/min = gr/cf

CFMNext, establish the process curve which most closely defines your application. The following applications are listed as guidelines.

The applications are defined by:- Process Gas Filtration: Dryers, Kilns, Reactors- Product Collection: Air Conveying, Size Reduction, Classifying- Nuisance Venting: Bulk Material Handling

To determine the Process Factor, use either:- Graph B1, if your grain loading is > 10 gr/cf- Graph B2, if your grain loading is < 10 gr cf

On the graph, find your grain loading and move horizontally to the appropriate application curve. Move vertically to the bottom of the graph to obtain Process Factor.

Step 3The air-to-cloth ratio is also affected by temperature and particle size. Graph C is used todetermine your Particle Size/Temperature Factor. Locate the temperature of your application and move horizontally to the appropriate particle size curve. Then move ver-tically to the bottom of the graph to obtain the Particle Size/Temperature Factor.

Step 4Calculate the air-to-cloth ratio: A.C.R. = A x B x C

Example:Ventilating a belt conveyor bucket elevator and screen handling, silica sand at ambienttemperature with an estimated inlet loading of 2 lb/min. Air volume is 5,000 CFM.Average particle size is greater than 10 microns.

A.C.R. = 8 x 1.1 x 1.0= 8.8 : 1

A filter’s design and cleaning mechanisms affect the final filter ratio. This additional equipment factor must be considered and is noted on the specific TechnicalData Sheet of the dust collector being considered. Consult your Sly representative or Slyat 1-800-334-2957.4

Sly’s Approach to AirPollution Control:• conservative design• flexible engineering• controlled manufacturing• comprehensive field

services

6

Founded in 1874, Sly has been providingsolutions to environmental problems sincethe turn of the century. From the beginning,we have done all our engineering andmanufacturing in-house.

Many companies makeair pollution controlequipment, but none havebeen doing it as long as Sly.

Nearly a century haspassed since our originalpatent for cloth dust filters.Over the years, we’velearned plenty about theapplication and fabricationof dust collectors andscrubbers. Here are themain points:

“In the pollutioncontrol business,conservativeapplication oftechnology is best.”

Equipment misappli-cation has no place in thepollution control business.Not only is improperequipment apt to fall shortof collection requirements,it is oftentimes moreexpensive to operate thanthe proper machinery. Forexample, incorrect sizingand improper media choicecan easily lead to excessivemaintenance and costlydowntime. When you dealwith Sly, we have your bestlong term interests inmind.

“We believe in fittingthe equipment to thecustomer’s needs, notthe customer to theequipment’scapabilities.”

Unlike many equip-ment suppliers, we refuse

to mass-produce product andthen hope for a good fit. Wehave maintained flexibility inour engineering techniqueswhich permit us tomanufacture each order tofit the task at hand, whilemaintaining a price to youthat is comparable to mass-produced equipment.

In many cases it costs nomore to get the very bestequipment for the job.

This approach earns usthe respect and repeatbusiness of many sophisti-cated buyers of pollutioncontrol equipment. Thesepeople, many of whom buydozens of collectors orscrubbers every few years,have always represented alarge portion of ourcustomer base.

“We build our ownequipment...for somevery good reasons.”

Part of the reason Slycan custom-make a collectorfor you while keeping acompetitive price is just that:we are the manufacturer.Unlike the majority of ourcompetitors, we don’t jobout our production. We doour own engineering,sewing, metal fabrication,painting, assembly, qualitycontrol, and laboratory R&D.This way we control everystep of the process, allowingus great flexibility to buildthe best collector or

scrubber for your individualneeds. We have a strongcommitment to shippingdates and routinelyguarantee ship dates whenrequested.

“Our obligation to thecustomer doesn’t endwhen the equipment isshipped.”

Sly’s staff engineers canpromptly assist you introubleshooting or withother field service problemsshould they arise at yourfacility. This commitmentto total customer supporthelps guarantee superiorvalue for your investment.

“We’re a privatecompany, and intendto stay that way.”

The corporaterestructurings and shortterm goals of today’sbusiness scene aren’t for us.Sly is owned and operatedby descendants of thefounding family. We are inthe business for the longrun, and will maintain theprofessionalism andcontinuity required tocontribute to the longterm success of yourbusiness.

7

All assembly and testing is performed in our ownplant. We control the quality and delivery scheduleto an extent not possible from other suppliers, mostof whom sub-contract much of their work.

Dust, fumes or vapors can occur singularly or in many combinations. Only a company with Sly’s level of experienceis capable of tailoring the correct air pollution controlequipment to your specific application.

All our collectors are made under ourroof...from cutting fabric for filterbags to painting.

Sly employs the most modern automated engineering techniques,allowing us to respond quickly with custom-tailored designs to fityour needs. Options and specials are no problem for us.

Sly TubeJet® dustcollectors offer on-linecleaning with a steadypressure drop. Bag changesare exceptionally easy withour “no tools required”design. Capacities to200,000+ CFM.

Easyinstallation; bags shippedinstalled. Capacities to100,000+ CFM.

Ask for our PacteconCatalog.

Collectors are cleaned off-line, cell-by-cell...contributing to long bag lifeand low compressed air consumption.Filter bags and bag cleaning systemare completely factory-installed.

10

Standard modules can be easily configuredto handle large air volumes.

11

Rectangular envelope bagsprovide several unique advantages: maximum filterarea in a minimum filter housing size, low headroomdesign, and safe side bagremoval from outside the collector.

Unlike most pulse-cleaned collectors, we use a downflowdesign which enhances particulate separation. Bag life isextended by minimizing cleaning cycles.

Shaker-Cleaned Envelope Bag Collectors

If your applicationpermits intermittentoperation, consider a SlyShaker collector, which issimple to operate andmaintain. Filtering velocitiesare low, which providesuniform dust distributionand long bag life.Accumulated dust isintermittently shaken offfilters while air flow istemporarily interrupted.

Ask for our Shaker Catalog.

12

Basic Criteria forSizing A Wet Scrubber

15

The first step is todetermine which type ofSly scrubber to select. Thenature of the pollutant orcontaminant will deter-mine if the Venturi,Impinjet, Packed Tower orcombination scrubbersystem is best suited foryour application. (Seepages 2 & 3.)

Sizing the scrubber isthe next step. The factorsaffecting sizing are gasflow rate, temperature,pressure, gas composition,humidity, contaminantloading and desired outletrequirements. Also, theavailability of an appropri-ate scrubbing liquid is animportant consideration.

Gas streams entering awet scrubber may or maynot be fully saturated,however they will exit thescrubber fully saturated.This process of saturationresults in a change involume, temperature anddensity.

The overall scrubbersize (diameter) is afunction of velocity ofsaturated gas through thescrubber shell. Knowingthe moisture content of agas stream (generallyexpressed as pounds ofwater per pound of drygas) and the inlet tempera-ture, the saturationtemperature and saturatedvolume content can becalculated. The volumecorrection chart at theright can be used for aclose approximation of thechange in gas volume.

Example:10,000 ACFM @ 450°Fcontaining 0.15# H2O/#dry air

The chart shows acorrection factor of 0.75.Inlet volume x correctionfactor = outlet volume or10,000 x 0.75 = 7500 ACFM.The scrubber would be sizedfor this saturated outletvolume.

For Impinjet scrubbersthe maximum capacity isbased on shell velocity of 500feet per minute. Dividing thecorrected or saturatedvolume by 500 yields theoverall tower cross-sectionalarea from which the diametercan be determined.

Example (continued):7500 ft3/min = 15 ft2

500 ft/min

Area = 15 ft2 = πD2

4D=diameterDiameter = 4.37 ft

The calculated diameterbecomes the reference pointfor equipment selection.(Refer to specific productcatalog.)

The approximateparticulate and/or mistefficiencies for Venturis andImpinjet scrubbers can bedetermined by the efficiencychart on the right.

To determine the numberof Impinjet stages requiredfor the absorption of gasessuch as acids requires acomplex calculation with toomany variables to use a

simple chart. However thefollowing information isimportant:- gas volume- process description- temperature- particle size- moisture content- type of contaminant
