Universal Holding Frames
AAF ’s Universal Holding Frames come in seven stan-
dard sizes that can be used individually or may be com-
bined to fit virtually any size filter bank. Each frame
includes a gasket to ensure a proper seal between the
frame and filter to minimize dirty air bypass. Also in-
cluded are AAF’s unique holding latches designed to
hold the filter in place and create a positive seal. The
latches are easy to use, requiring only a simple twisting
motion to release the filter.
Universal Holding Frames are constructed of galva-
nized steel. The frames are available in 304 stainless
steel, and there is an aluminized steel version for high
temperature applications. (Note: 304 stainless and alu-
minized steel frames are slightly different in appear-
ance but are of the same high quality and durability as
the galvanized steel models.) All frames feature holes
on each side for bolting or riveting into filter banks.
Seven sizes are available: 24 x 24, 20 x 25, 20 x 20,
16 x 25, 16 x 20, 20 x 24, and 12 x 24. The 2-13/16”
deep frame will support all standard combinations of
pre and final filters.
High Temperature Applications
Filtration systems for paint curing ovens and other high
temperature applications can be served using an alumi-
nized steel Holding Frame constructed without a gas-
ket. The aluminized steel frame will tolerate tempera-
tures up to 900°F. The standard gasket is good for tem-
peratures up to 140°F.
Filter Latches
AAF latches are available to hold a variety of filters
and filter combinations, are replaceable, and specifi-
cally designed for upstream or downstream servicing.
Each latch is annealed to music wire specifications af-
ter forming, and commercially zinc plated to provide
years of service under varying environmental condi-
tions. The Universal Holding Frame sides feature a
unique retaining tab to hold the “L” Series latches. “L”
Series latches do not connect to, or disturb, the flat seal-
ing flange and gasket surface.
NOTE:
The Universal frames are constructed of galvanized steel.
Also available in 304 stainless steel.
The L-42 and L-44 latches, specifically designed for
the VariCel
®
II filter in combination with prefilter, offer
an additional advantage. The latch can be turned to
release the prefilter while maintaining a pressure seal
on the higher efficiency VariCel II filter.
Conversion Latches
AAF sells “Knock On” latches to allow installation of
all combinations of AAF filters in other manufacturers‘
filter holding frames.
Frame Bank Stiffeners
Vertical stiffeners are furnished with larger frame banks
to ensure rigidity under normal operating conditions.
