General
Flanders Pre Pleat 40 extended surface pleated fil-
ters are designed to operate in most every type of
installation. Available in 1”, 2”, and 4” nominal
thickness, these filters have an average atmos-
pheric dust spot efficiency range of 25-30% per
ASHRAE Standard 52.1 test methods. Pre Pleat
40 filters offer greater efficiency and service life
than disposable filters, pad and frame systems, or
metal washable filters. The overall design of this
product makes these filters the accepted choice in
applications requiring high performance and
extended service.
These filters are suitable for variable air volume
systems. Operating face velocity ranges are from
0 to 500 fpm for 1” and 2” filters, and from 0 to 625
fpm for 4” filters. Standard and High Capacity
designs are offered.
Pre Pleat 40 filters are UL 900 Class 2 listed but are
available with UL Class 1 listing.
Versatility
Most heating, air conditioning, or ventilating sys-
tems can be upgraded with the use of Pre Pleat 40
filters in place of existing flat panel types.
The inherent strength of the filter allows for easy
changeout as it will not collapse, warp, or bend in
normal service.
Pre Pleat 40 filters are available in a wide range of
sizes and will fit most commercial and industrial
installations with little or no system modification.
Fasteners are available to adapt the filter to exist-
ing filter banks.
Installation Considerations
Pre Pleat 40 pleated filters are suitable as primary
filters and can be installed in Type 9 Holding
Frames, K-Trac Framing Modules, Surepleat Side
Access Housings and similar existing hardware.
They may be used as prefilters for Precision Pak,
PrecisionCell and Rigid-Air filters in these framing
systems and in Sureseal Side Access Housings.
