port. The media overlaps the support, which pro-
vides a gasketing effect reducing air bypass around
the filter.
A tackifier is applied in between the last two layers
to stabilize any migrating particles and prevent the
discharge of particles from the filter. The graduat-
ed media design produces a superior dust holding
capacity that will outlast most filters on the market.
Panel filters are 100% moisture resistant and will
not warp or deteriorate in wet or humid conditions.
By utilizing one continuous panel in a filter track,
and its selvedged edge, a panel filter eliminates air
bypass so common among cardboard framed fil-
ters.
When measuring the correct filter for your booth,
first measure the entire filter track. This measure-
ment should have a track height of 14-25” and a
length of 14-100”. The height of the 2 Ply Panel is
listed as a nominal size. For instance, if a filter ring
measures 15.5” x 19.5”, then the correct size is 16”
x 20”. There are hundreds of standard sizes avail-
able. Custom sizes are also available.
Model 40 Standard Capacity Pleat
Models 80055.xxxxxx
For use as a prefilter in downdraft booths. Model 40
Pleats are designed to operate in almost every type
of installation. Available in 1”, 2” and 4“ nominal
thicknesses, these filters have an average atmos-
pheric dust spot efficiency range of 25-30% per
ASHRAE Standard 52.1 test methods. Model 40
Pleats 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 applica-
tions requiring high performance and extended
service.
Filter frames are constructed from two pieces of
die-cut, moisture-resistant carrier board.
Components”telescope” into one another and pro-
vide double-wall construction and a precision fit.
The frame includes diagonal and horizontal support
members bonded to the media on the air entering
and leaving sides for unsurpassed frame strength,
locking corners and positive media-to-frame seal
reduces the possibility of air bypass.
The filter is made from fully synthetic, high-loft and
reinforced media. It is continuously laminated to an
expanded metal grid on the air leaving side to pro-
vide pleat stability throughout the life of the filters
and prevent media flutter while in operation. The
unique v wedge allows for total media usage and
provides maximum air flow.

Models 11255.xxxxxx
These are heavy duty synthetic filters for use as
prefilters in downdraft booths.HD Industrial Grade
filters are designed for use in any application where
disposable panel filters are recommended. They
can be relied upon for superior performance since
they are specifically designed for heavy work-loads.
Both standard and special sizes are available.HD
Industrial Grade filters are designed with a one-
piece moisture-resistant chipboard frame enclosing
progressive-density media. Standard frames are
nominal 1” thick (3/4” actual) and nominal 2“ thick
(1-5/8“ actual).
