High Quality Prefilters
● Excellent media perfor-mance in high humidity conditions
● High tensile strength media
● Environment-friendly materials
● Sturdy, reliable construction
High performance, environmentfriendly mediaWith the new AmAir 100 and 300series of prefilters AAF has risen tothe challenge of designing anenvironment-friendly product withthe necessary performance charac-teristics built-in. These filters featurea new 100% synthetic media packwhich provides excellent perfor-mance in conditions of high relativehumidity and moisture. When themedia becomes wet, resistance mayrise temporarily only to subside whenthe media starts to dry. The syntheticmedia displays great tensile strength,reducing the chance of damageduring handling and operation. Themedia is environment and user
friendly: it does not contain anyharsh resins or artificial colouring. Itcan therefore be readily disposed ofby landfill or incineration.
Sturdy, reliable constructionThe pleated media pack of bothrange of filters is housed within asturdy double walled, die cut box,beverage board frame. To ensure themedia pack does not rack ordeteriorate under difficult operatingconditions, it is bonded to the insideof its frame at all points of contactand retained in position by retainersat the air leaving and air enteringsides. On the air leaving side of themedia pack a wiremesh pleat supportgrid maintains equidistant spacing
between pleats, ensuring that dust iscollected evenly over the entiresurface of the media. Media usage ismaximized resulting in a moregradual rise in resistance, which inturn has a positive effect on energyconsumption and service life.
Applications Classified G4 in accordance with EN 779, AmAir 100 and 300 areideal for protecting more expensivesecondary air filters from prematuredust loading and replacement. Asprimary filters, they will also helpreduce HVAC maintenance costs bypreventing unnecessary dust build-upon coils, fans and duct work.

High Temp Series VariCel filters are designed for sys-tems operating from 350˚-900˚F. Constructed of alu-minized steel, High Temperature VariCel filters offer
rated efficiency with proven reliability over the life of the filter.See page 4 for models and temperature limits.
Type NH Series VariCel filters are designed for specialsizes and applications, including incineration andcompaction disposal systems. Manufactured of fire-
retardant, 3⁄4" thick, heavy wall particle board, Type NH VariCelfilters (U.L. Class 1) are operable at temperatures up to 200˚F.The filters are constructed without headers and cell sides areflush with front face dimensions.
VariCel® andVariCel® with Intersept®
Extended Surface Supported Pleat Filters
■ Available In Three Efficiencies 90-95% (MERV 14), 80-85% (MERV 13), 60-65% (MERV 11)
■ Available with Intersept® in 90-95% & 60-65% efficiency
■ U.L. Class 1
■ Ideal For Difficult Operating Conditions
- Variable air volume- Turbulent airflow- Repeated fan shutdown- High temperature operation- High humidity- Intermittent exposure to water
such as seacoast installations
VariCel filters with Intersept® antimicrobial are designed specifical-ly to improve Indoor Air Quality (IAQ). Air filters are designed totrap and concentrate particulate air contaminants including viablefungal and bacterial spores. The presence of Intersept® antimico-bial preservative in the filter media is intended to preserve the in-tegrity of the media throughout the useful life of the filter.Antimicrobial preservatives are not meant to increase the efficiencyof the filter, nor to kill microorganisms "on the fly" as they passthrough a filter. Intersept® is EPA registered and environmentallysafe.
Engineered For A Variety Of Applications
Designed To Improve Indoor Air Quality
Type SH Single Header VariCel filters are designed forsystems originally supplied by AAF International. A
unique 13⁄16" flanged header on the air entering side al-lows the filter to be easily inserted and latched into front andside access systems.
Type DH Double Header VariCel filters are designed toupgrade air cleaning performance and reliability. Two13⁄16" thick flanged headers make the filters compatible
with the holding frames and latching devices of various manu-facturers, including rear access systems.
XL Series VariCel filters, single header (XL-S) and double header(XL-D), contain up to 67% more media and offer more than twice theservice life of standard single and double header models.
Corrugated Aluminum Separatorswith Rolled Edges maintain uniformpleat spacing for optimum airflow. Theseparators are rolled to eliminatesharp edges, preventing media dam-age during shipping and personal in-jury during installation.
Crimped Rear Flanges (SH) are rolledover and riveted to add strength, elimi-nate sharp edges, and prevent bypassleakage.
Media Pack RestraintSteel brace on air leavingside adds support to themedia pack.
Media Pack Sealant — A layerof high efficiency media seals themedia pack into the cell sides.The media sealant prevents by-pass leakage and damage to themedia and separators duringshipping and handling. By allow-ing slight movement of the mediapack when the filter is jarred, thecushioning sealant helps preventtears and punctures to the media.
VariCel media is manufacturedwith two layers of glass fibers:coarser fibers on the air enteringside and finer fibers on the airleaving side.
Our dual density design allowsdirt particles to be collectedthroughout the entire depth ofthe filter utilizing the full clean-ing potential of the media. Maximum dust holding capacity ex-tends the life of the filter, minimizing operating costs.
The water resistant media can withstand intermittent exposure towater, making VariCel filters ideal for installations in humid areasor where the filters are exposed to moisture.
DUAL DENSITY MEDIA REDUCES OPERATING COSTS
FINER FIBERSAir leaving side
COARSE FIBERS Air entering side
AIRFLOW
VariCel's rigid constructionwith supported pleat mediapack maintains a compact,unitized structure even undertough operating conditions.Variable air velocity and re-peated fan shutdown do notcompromise performance.
Unitized Construction
Interlocked header and cellsides, along the entire lengthof each side, provide maxi-mum sealing. Competitive fil-ters are designed with loosefitting headers which allowgreater potential for bypassleakage.
BUILT RUGGED FOR DEPENDABLE PERFORMANCE
Pleats and Separators Bonded For Strength
During the pleating process,spots of glue are applied tobond each separator to the ad-jacent pleat. This solidifies themedia pack to minimize move-ment and prevent media dam-age. Burst strength isincreased to prevent the filterfrom blowing out under vari-able air volume conditions orunusually high resistance.
Galvanized steel headers andcell sides resist damage duringshipping and handling, andprevent corrosion over longservice life. (HT VariCel filtersare constructed of aluminizedsteel.)
Easy Installation
Rigid construction and mini-mum depth make VariCel fil-ters easy to install in all typesof systems.

Non-Laminar Flow CleanroomsBasic Design and Operating Considerations
B E T T E R A I R I S O U R B U S I N E S S ®
In a non-laminar cleanroom or, to use itsofficial name, non-unidirectional airflowcleanroom, air enters the room via filtersin the ceiling, and is exhausted via grillesin the wall close to the floor. The principle of this technique is basedon allowing air to flow along irregular,random paths in a turbulent way.
The success of this technique hinges onoptimizing the mixing of clean incoming
air with dust laden air in the room andthereby diluting the contamination levelin the cleanroom and lowering thenumber of particles per m3. The supplyof clean air is therefore the factor whichdetermines the success of this technique.In general, the greater the frequency withwhich the air is renewed the lower thecontamination build-up in the room andthe greater the rate with whichimpurities are diluted. On an hourly
basis, the number of air changes in aroom can vary between 10 and 50,depending on the type of work and theachievable Class of the room.
Although more unpredictable thanlaminar airflow cleanrooms, in manyapplications a non-laminar flow roomcan be a cost effective solution, especiallywhen local laminar flow work stationsare operational in the room.

Laminar Flow Cleanrooms
The principle of laminar airflow or, tobe more precise, unidirectional airflowcleanrooms is based on air moving alongparallel streamlines at a uniform velocityof 0.3 to 0.45 m/s with as littleturbulence as possible between the placewhere the air enters and exits the room.The principle is based on expelling anydust in the airflow by the shortest route.
Basically, there are two types of laminarairflow cleanroom:a) Vertical downflowb) Horizontal crossflow
Vertical DownflowIn a vertical downflow cleanroom, airenters the room via filters in the ceilingsurface and is exhausted via a perforated
floor. This downward aiflow flushescontaminated air particles out of theroom via the floor, thus preventing abuild-up of contaminated particles.Particles generated at one work stationare therefore removed before they havethe chance to migrate. The air velocityin this type of cleanroom is usually 0.3to 0.45 m/s.
Horizontal CrossflowIn a horizontal crossflow cleanroom, thedirection of airflow is from left to rightor right to left across the room. Airenters the room via filters in one walland is exhausted and/or recirculated viaa bank of filters and perforated panels inthe opposite wall. The air velocity has tobe established at a sufficiently high level,
usually 0.45 m/s, to counter the effectsof upward thermal movement ofparticles. In work stations close to thehigh efficiency filter wall, Class 100 orbetter is possible.
Since the flow of particles in this type ofcleanroom is in the horizontal direction,the particle contamination generated atone work station can be transported towork stations further downstream of thefilters. This, however, is dependent onthe type of work or the process(es) beingcarried out in the cleanroom. Horizontalcrossflow is nevertheless a very practicaland cost effective system, particularly incleanrooms which have to be built inexisting spaces with limited ceilingheight.

New European Standard for Coarse and Fine Filters
In 1993, the European Committeefor Standardization, TechnicalCommittee 195, Work Group 1(CEN/TC195-WG1) established anew standard for general ventilationfilters. With the introduction of thisstandard under document name EN779, member countries of theEuropean Union are obliged to issuetheir own national version of thisstandard within the existingframework of their own nationalstandards organizations. For example, BS EN 779 in the U.K.
and DIN EN 779 in Germany.EN 779 is based on existingdocuments such as EUROVENT4/5, and ASHRAE 52.1:1992, but isin fact more stringent than either ofthese standards. The standardincorporates a new system ofclassification for Coarse and Finefilters based on an average dust spotefficiency at a specified final pressuredrop.
Filters with an initial dust spotefficiency below 20% are classified as
Arrestance Filters (Coarse Filters) inthe range G1 - G4. Final pressuredrop for certification is specified at250 Pa maximum. Filters with aninitial dust spot efficiency above 20%are classified as Efficiency Filters(Fine Filters) in the range F5 - F9.The final pressure drop forcertification is set at 450 Pamaximum.
The table summarizes theclassification of the EN 779 forgeneral ventilation filters.

Note:For your information, the CEN/TC 195 Work Group 1 will continue to upgrade its standardization for general ventilation filters. To this end, EUROVENT has produced a particle count method under document name EUROVENT 4/9 which will form thebasis for a future new standard. WG 1 has also expressed its intention to work in closer liaison with ASHRAE on this subject.

● On a flat sheet of media, the MPPS is determined for the given media velocity. This can be done with a laser spectrometer or a combination of electrostatic classifier and CNC (Condensed Nucleus Counter).
● The filter is assembled with the specified media grade and amount of media to comply with the defined media velocity.
● The filter is challenged with an aerosol and at the MPPS both the local and overall efficiency is determined with either a CNC or laser spectrometer.
● Leaks are specified as maximum allowable local penetration at the MPPS and must not exceed 5 x the overall penetration.
● The filter is classified according to the test results in the range H10 - H14 for HEPA,U15 - U17 for ULPA.

Notes:• Filters in the class H10, H11 and H12 do not require verification of local penetration.• Filters in the classification H13 and H14 may, as an alternative, be verified with the visual oil-smoke test (previously known as DIN 24.184),
which is accepted as equal or more searching than the specified local penetration.• U17 is an exception to the rule. In this case local penetration may not exceed 20 x the overall penetration value.

Motors and controlsThe unit is available with traditionalhigh efficient AC motors, operatingwith single phase or 3 phase motors.Controls can be either with 5 stepspeed controller or stepless controller.This execution provides a simple andreliable economical solution formany applications.
Utilizing EC system (electricalcommutated) external rotor motorsgreatly reduces the powerconsumption of the unit, because ofreduced losses. Consequently thecooling requirement is also reduced.
Controls include the electroniccommutation unit, standard singleunit control, standard RFI supressionand PFC (power factor controller )and LON® bus interface. Two wiretwisted cable installation to the busmakes installation easy. Mains supplyis single phase 230-270V 50/60Hz.
AstroCel II HEPA and ULPA filtersThe unit is equipped with HEPAfilters in Class H14 to EN 1822 orULPA filters Class U15, U16 orU17. All filters are factory scanned tothe European Standard to ensure
leakfree operation. Selected lowpressure drop of the AstroCel IIprovides, in combination with thehigh total static pressure of the fan, afree static pressure of 70-100 Pa atfull rated airflow. This results inextended filter life or it can beutilized for external use on prefiltersor cooling coils.
Options• Room Side Change (RSC)• Cooling coil• Individual ceiling frames• 60 Hz operation
