These products are similar to the FH and
FSH series, except that the FRH and FCRH
series are two-stage filters. The second
stage consists of a battery of 12 cartridge
filters for each 20" 3 25" 3 2" prefilter.
The high-efficiency P-5 cartridge filters have
threaded ends that screw into individual
receptacles. As each P-5 filter is removed
and replaced, less than 4 in 2 is exposed
to the flow of unfiltered air, so “hot
swap” changeouts (while the system is in
operation) are an option for these units.
Usually, a moderately efficient filter panel is

used as the first-stage element. The FCRH
series has an integrated silencing section
that provides moderate noise reduction.
All units are fabricated of steel sheet and
plate, welded throughout to provide a
rugged, long-lasting, trouble-free air filtering
component. All models are equipped with
a pressure tap and flange drilled to match
125/150-lb ANSI specifications. Inside and
outside surfaces are primed and given a
finish coat of enamel paint. All housings
come with low-profile, UV-stabilized highdensity
polyethylene weather louvers.

Nominal capacity is based on an exit velocity of approximately 5,000 ft/min. Filter element capacity may be greater, but this is unrelated to unit capacity.
2”-deep filter frames will hold single or dual elements. Refer to page 8 for filter element details.
