Deep-pleat Coarse Filter
DESCRIPTION
The filters incorporate a 100% synthetic media with an ASHRAE 52.1
average atmospheric efficiency of 30% to 35% and an average arrestance
exceeding 90% by weight. The 1¡åand 2¡åfilters handle velocities of
up to 500FPM, the 4¡åfilters up to 625FPM.
The media is chemically bonded to a metal grid on the air-exiting
side, preventing fluttering, and maintaining uniformity of the pleats.
That filter pack is enclosed in a heavy-duty, moisture resistant,
die-cut frame that will not warp, crack or distort under normal
operating conditions.
Diagonal front and back media retainers are an integral part of
the filter frame. The media pack is bonded to every part of the
frame, preventing any possibility of air bypass.
