CLEAN ROOM HEPA BLOWERS
Halco HEPA Blower Modules are available in many different sizes and configurations including low profile design, reverse flow applications, and high efficiency motor designs.
BLOWER BOXES
Suitable for customer applications
HEPA BLOWER W/ LIGHT
Suitable for cleanroom environments there is no available space for lights.
GREEN POWERED HEPA BLOWERS
Suitable for cleanroom environments where environmental considerations are necessary.
LOW PROFILE UNITS
Suitable for cleanroom environments where there are space constraints in the ceiling.
STANDARD UNITS
Suitable for standard cleanroom environments where there are no space constraints.
HIGH POWERED UNITS
Suitable for cleanroom environments where extra C.F.M. is needed
REVERSE FLOW UNITS
Suitable for cleanroom environments where air need to flow out of the room.
HEPA FILTER MODULES
HEPA Filter Modules are Suitable for customers who need filtered air but already have a make up air unit providing C.F.M.
ECONOMY UNITS
Suitable for budget conscious customers who need filtered air.

IDITEMQUESTIONANSWER
15hepa_blowerIs there a cord that is included on the blower units?Cords are not standard because most units are hard wired, if you would like a cord please specify, a fee may apply.
17hepa_blowerWhats the difference between AT2000 & FT Blower Unit?The FT Hepa blower unit has a 1/2 h.p. horse power motor with a centrifigul blower and is capable of reverse air flow - The AT2000 has a 1/4 h.p. backward inclined fan motor and is not capable of reverse air flow.
19hepa_blowerCan the AT2000 Unit be wired to reverse the air flow?No, the unit is not capable of reverse flow, but the FT unit is capable of reverse air flow.
54hepa_blowerWhat is the difference between the FT Unit and the FTE Hepa blower unit?The FT is a removable core hepa which give the customer the ability to change the hepa filter. FTE, the hepa is bolted into the unit and is unreplaceable.
56hepa_blowerWhat efficiences are available for the unit?Standard is 99.99%, but other efficiencies are available at customers request.
57hepa_blowerWhat is the size of the hepa filter in a verti flow for replacement purposes.It is roughly 2' x 4'
59hepa_blowerDo you have a static pressure graph for the FT units?There is no SP chart available for this unit. Customer needs to supply what SP you need to deliver the 600 CFM we rate the unit for & then we supply the correct blower & motor to deliver that SP. The stand unit is only rated with a SP of 0.25” WG added external. The 2 x 2, due to the size restriction of the blower box is only good for an external SP of 0.15” WG. customer needs to know the “system” that these are to be used in to properly size them.
61hepa_blowerCan I achieve +0.04 Inches of water(H2O) with an AT2000?Yes. However we recommend the FT Series Hepa Blower Units which use a larger centrifugal blower and is only slightly more money.
62hepa_blowerCan I achieve 3-5 Air Changes per Hour (ACH) with an AT2000?Yes. Our unit will provide up 20 (ACH) comfortably.
63hepa_blowerWhat is the difference between the T-Mod and The Vertiflow Series?The Vertiflow has a replaceable HEPA core, while the T-Mod HEPA can not be replaced.
64hepa_blowerwhen do you need a prefilter and when do you need a duct connection? 
65hepa_blowerWhat is the difference between the AT2000-1 & AT200-3?The AT2000-3 Has a replaceable filter where the AT2000-1 does not have this ability.
70hepa_blowerDoes the verti-flo unit come with the filter?Yes.
71hepa_blowerHow do I know how many hepa blowers I need in my cleanroom application?IT IS TOTALLY DEPENDENT ON YOUR REQUIRED CLASS AND ROOM CONFIGURATION. SEE BELOW FOR GENERAL EXAMPLE OF HOW TO CALCULATE BASED ON A SAMPLE SOFTWALL CLEAN ROOM [10,000 ENVIRONMENT] = ISO 7 OF 6' X 12' X 12' H. - BARE MININUM FOR CLEANROOM (10,000) AIR FLOW IS 20 AIR CHANGES PER HOUR (ACH) - 864 CUBIC FEET X 20 (ACH)= 17,280 CUBIC FEET PER HOUR (CFH) / 60 MINUTES = 288 CUBIC FEET PER MINUTE (CFM) - ONE PASS JOB (SOFTWALL APPLICATION) - TRIPLE AIR FLOW CHARACTERISTICS (288 X 3 = 864 C.F.M.) IS NECESSARY FOR THE ROOM = 2 HEPA BLOWER UNITS - CLOSED RECIRCULATED HARD WALL SYSTEM (HARD WALL APPLICATION) (288 X 1.25) = 400 C.F.M.) = 1 HEPA BLOWER UNIT
73hepa_blowerCan you build smaller Hepa Blower Units (8" x 8" or 12" x 12") with a motor inside of them?Yes. We can, but it is suggested to go with the FT2424 Unit because of pricing.
80hepa_blowerDo I still need a prefilter if I get a duct connection on the AT2000?If you get a duct connection the prefilter will be located somewhere in your ductwork system and you will not need one in your unit. If your unit is not ducted you are recirculating air within the room and will need a prefilter.
81hepa_blowerCan any of the blower units be built for reverse flow?All FT Units can be built for reverse flow, AT2000 Units can not.
94hepa_blowerHow often should I change the filter in the hepa blower unit?Filter changing is partially based on the cleaniless of the cleanroom but some general signs are when you feel a drop in velocity of the hepa blower or in filter pressure.
100hepa_blowerWhat is the difference between the FT 6M & 3M Unit?The 3m has a 3 1/2" Filter available in gasket or gel seal, 6m model has a 5 7/8" filter available in gasket only.
116hepa_blowerAre Halco Units CSA or ULC ApprovedYes, Halco uses all U/L & CSA Components
118hepa_blowerHow do I wire up my blower unit? 
126hepa_blowerHow do I achieve positive pressure in my clean room?There are many variables in a cleanroom environment and systems have to anaylzed to achieve the required pressure based on all the design criteria and variables. There is no one single answer. Every job is unique.
