CONSTRUCTION The Heavy Duty Filter is a heavyweight aluminum
filter. It consists of multiple layers of aluminum expanded material,
assembled in alternating layers to assure maximum filtering and
internal loading capabilities. The media is enclosed in a heavy
weight aluminum frame, mitered and secured at one corner by rivets.
Designed with an extra layer of heavier diamond grid to protect the
finer layers behind, these filters can stand up to rigorous handling
that some other lighter filters can not withstand.The filter is designed
for applications such as industrial, commercial, schools, office
buildings, hospitals, and hotels where a heavy duty permanent filter
is recommended. Maximum operating temperature on the Heavy Duty
Filter is 275 degrees F. Available in both standard and special sizes.
Available in 3” and 4” thicknesses.

Aluminum, commercially known as 3003-H22, .025 in thickness
expanded to .065 strand. Frame shall be made from sheet Aluminum
