(see pages 42 and 43 for number and quantity of filters per model)
2" flat filter section with choice of three standard filter types:
• 2" throwaway filters
• 2" 35% efficient pleated filters
• 2" permanent high velocity cleanable filters
4" flat filter section:
• with 4" 35% efficient pleated filters
High capacity filter section with choice of three standard filter types:
• 2" throwaway filters
• 2" 35% efficient pleated filters
• 2" permanent high velocity cleanable filters
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.
