Application Guidelines

Rigid-Air filters may be used wherever job require- ments and available space will accommodate 6” or 12” deep filters.

Rigid-Air filters should be selected using 24” x 24” and 24” x 12” face sizes. This allows for 12” incre- ments 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 ver- tical 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 pub- lished recommended velocities. Rigid-Air filters may be applied at any capacity between zero flow and cataloged capacities.

Hospital Applications

Rigid-Air filters may be used on the downstr am side of the supply fan in hospitals if th y a far enough from the fan so that the high fan discha ge velocity will not affect them. Rigid-Air igid filte s can withstand adverse air flow c nditi ns better than bag filters and are the preferred selecti n for these applications.

Gasketed Headers

Rigid-Air headered filters in talled 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 he ders, dd suffix “S” or “H” to the model number. Ex mple:

Model Number - S: G skets are on the sides paral- lel to the pleats.

Model Number - H: Gaskets are on the sides per- pendicular to the pleats.
