Pleated Media

Pleated (extended surface) filters provide

more surface area than conventional

filters due to the fore and aft pattern of

the pleat. An increase in surface area

results in increased contaminant holding

capacity and service life while reducing

energy costs.

A variety of media compositions, efficien-

cies and operating temperature ranges are

available. Both natural and synthetic

materials are used in the make-up of the

media: cellulose materials, fiberglass and

blends of cotton and polyester.

Depending on the air cleaner and the ap-

plication, the pleated filter may be the

primary filter or the second stage of a

multi-stage unit.

Adsorber Filters

Unlike particulate filters, odors in the form

of undesirable gases and vapors are most

commonly removed from the air stream

by the process of adsorption that is en-

hanced by multi-faceted porous surfaces

of certain materials. Filter trays in a vee-

bank configuration of activated carbon or

optional potassium permanganate pellets

effectively facilitate the adsorption of these

odor and gas contaminants.
