300X
AmAir

300X filters are constructed with AAF’s totally unitized, double
wall, die-cut box, beverage board frame. The media pack is bonded
inside the frame at all points of contact. AmAir 300X filters are built
rugged for durability and reliability under tough service conditions.
AmAir 300X is rated MERV 7 (25-30% average ASHRAE efficiency).
Superior Strength
AmAir 300X filters are extremely strong and durable, with all
components rigidly bonded into a totally unitized construction.
They will not rack or deteriorate under normal operating conditions,
including high moisture applications.
An expanded metal grid laminated to the air leaving side of the media
creates more consistent pleat shape and maintains uniform pleat
spacing. Expanded metal also increases the stability of the pleat pack,
reducing media flutter during operation.
The media pack support retainers, which are an integral part of the
frame, are bonded to the pleats on both the air entering and the air
leaving sides. This increases rigidity and also helps maintain proper
spacing between pleats for maximum dust holding capacity while
minimizing resistance.

HT High Temperature
AmAir
®
HT is designed for
applications with continuous
operating temperatures up to
500˚F (260˚C). AmAir HT is
rated UL Class 1 with 30-35%
average ASHRAE efficiency. The
frame is an aluminized steel
U-channel, with the media pack
bonded to the inside on all four
edges. An expanded aluminized
steel faceguard is spot welded
inside the frame on the air
leaving side to retain the media
pack at elevated temperatures.
AmAir HT is made with micro-
glass media.
• Expanded metal pleat support grid (AmAir

300X)
• High loft media increases dust holding capacity
• Excellent primary filter to prevent dust build-up on
heating and cooling coils, fans, and ductwork
• Excellent prefilter for higher efficiency filters
• Directly interchangeable with disposable panel filters,
media pads in metal frames, or permanent filters used
in built-up filter banks and side access systems. No
modifications are necessary to frames or latches
• 4" filters have pleat stabilizers to ensure uniform
spacing and increase rigidity (AmAir
