Precisionaire MERV 10-14 manual Application Guidelines, Hospital Applications, Gasketed Headers

Application Guidelines

Rigid-Air filters may be used wherever job requirements 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" 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.

Hospital Applications

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.

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.

To specify headered version Rigid-Air filters with gasketed headers, add suffix “SA” (side access), “GU” (upstream), “GD” (downstream) and “GS” (sides) to the model number.
