General

Rigid-Air extended media surface rigid filters are designed for use in most commercial or industrial HVAC systems where medium to high efficiency fil- tration is required.

They feature your selection of media backed with expanded metal and pleated. The pleats are held in place by rigid pleat separators, now available in either plastic or metal styles. Rigid-Air is available in two media types: lofted fiberglass and micro-fine synthetic with average efficiency ranges of 50-55%, 60-65%, 80-85% and 90-95% per ASHRAE Standard 52.1 test methods.

These filters are especially suitable for variable air volume systems. Operating face velocity ranges are from 0 to 375 fpm for 6” deep filters, and from 0 to 675 fpm for 12” deep filters. Two frame styles are available: a single header model and a box type without header. Rigid-Air filters are UL 900 Class 2 listed. Optional Class 1 listed are available with metal inserts and fiberglass media.

Installation Considerations

Rigid-Air filters may be installed in Type 9 Holdi g Frames, K-Trac Filter Framing Modules, Surese l Side Access Housings or in similar existing h rd- ware. Type 9 Holding Frames are riveted together

to form a bank and may be installed f r upstream or downstream service. K-Track Fil er Framing Modules are especially suitable for medium to large built-up filter banks. Smaller sys ems and systems

with minimum upstream acce	pace are best
served using Sureseal Side Acce	Housings.

The headered version should be selected for use with the hardware listed above. If the filter is to be installed so that it protrudes upstream of the Type 9 Holding Frame, the box style filter is required.
