(Dimensions, Page 29 to 37)

 

 

 

 

Prefilters: select either 2" throw-away or 2" 35% efficient filters as prefilters. All three high efficiency filter sections accept prefilters, without reducing final filter depth capacity.

•2" high efficiency filter section (accommodates up to 12" of final filter depth):

•Prefilter and either 6"or 12" cartridge filters at 60% to 65%, or 80% to 85%, or 90% to 95% efficiency

•28" high efficiency filter section (accommodates up to 21" of final filter depth):

•Prefilter and 21" bag filters at 60-65%, or 80-85%, or 90-95% efficiency

•44", high efficiency filter section (accommodates up to 37" of final filter depth):

•Prefilter and 30" bag filters at 60% to 65%, or 80% to 85%, or 90% to 95% efficiency

•OR prefilter and thirty-seven inch bag filters at 60% to 65%, or 80% to 85%, or 90% to 95% efficiency

High efficiency filter section options:

•1" depth by 3/4 lbs per cu. ft. density fiber glass insulation (standard section not insulated)

•Diffuser section, must be used when high efficiency filter section is downstream of fan (blow-through unit)

•Double wall construction on high efficiency filter section, adds 4" to the width and 2" to the height of the unit. Insulation is 2" depth and 1.5 lbs per cu. ft. fiberglass. The insulation is sandwiched

between standard unit and outer skin.
