Rigid-Air

Spun Glass or Synthetic Media Rigid Filter

Bulletin PB1001-1106

General

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

They feature your selection of media backed with expanded metal and pleated. The pleats are held in place by rigid pleat separators, available in either plastic or metal styles on 12"depth filters. 6" depth filters feature rugged fiberboard separators. 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 and MERV 10-14 per ASHRAE Standard 52.2.

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 Astr Holding Frames, K-Trac Filter Framing Modules, Sureseal Side Access Housings or in similar existing hardware.

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

Physical Data

Frame: 24 ga. corrosion-resistant steel doubleturned flange makes a stronger frame.

Media: Lofted fiberglass or micro-fine synthetic.

Media Supports: Expanded metal grid with metal or plastic pleat separator.

Face Grid: Horizontal and diagonal metal supports.

Header: 13/16" wide 26 ga. corrosion-resistant steel.

Operating Limits: 180° F 100% RH%.

Actual Header or Box Filter Face Size: Nominal size less 5/8" (e.g., a nominal 24" x 24" filter is actually 23 3/8" x 23 3/8").

Actual Depth: 5-7/8" or 11-1/2".
