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". Important Features • Ecologically advanced filtration medium made entirely from recycled materials. • Rugged corrosion-resistant steel casing minimizes damage during shipping and handling. • Lofted fiberglass micro-fine or synthetic media is held in position by upstream and downstream plastic or metal pleat supports. • Units are available with or without header. • Filters are completely rigid. • MERV 10-14 Flanders PrecisionAire ~ Foremost in Air FiltrationToll Free: 1-800-637-2803 Notes: 1.

Rigid-Air filters should be selected using 24" x 24" and 24" x 12" face sizes. This allows for 12" increments in height and width of the filter bank and insures that replacement cartridges will be readily available. Rigid-Air filters should be installed with pleats vertical wherever possible. It is permissible to install 24" x 12" face size cartridges with pleats horizontal if necessary to meet the size requirements of the filter bank. VAV Systems Filter banks should be sized so that the maximum rated flow at design conditions falls within the published recommended velocities. Rigid-Air filters may be applied at any capacity between zero flow and cataloged capacities. Rigid-Air filters may be used on the downstream side of the supply fan in hospitals if they are far enough from the fan so that the high fan discharge velocity will not affect them. Rigid-Air rigid filters can withstand adverse air flow conditions better than bag filters and are the preferred selection for these applications. Gasketed Headers Rigid-Air headered filters installed in Flanders K- Trac Filter Framing Modules or Sureseal Side Access Housings require gaskets on opposite header sides to prevent air bypass. To specify headered version Rigid-Air filters with gasketed headers, add suffix “SA” (side access), “GU” (upstream), “GD” (downs...
