Application Guidelines

PrecisionCell filters may be used wherever job requirements dictate totally rigid filters and available space will allow only minimal inline depth.

PrecisionCell 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.

PrecisionCell filters should be installed with separa- tors vertical where ever possible. It is permissible to install 24” x 12” face size cartridges with separators horizontal if necessary to meet the size require- ments of the filter bank.

Prefilters

We recommend that Prepleat 40 pleated panel fil- ters or Precision Pak bag filters be used as prefilters for PrecisionCell installations. Where there must be long intervals between filter changes, we recom- mend using 65% ASHRAE rated PrecisionPak as prefilters. Refer to individual bulletins for perform- ance data on these prefilters.

VAV Systems

Filter banks should be sized so that the maximum rated flow at design conditions falls within the pub- lished recommended velocities. PrecisionCell filters may be applied at any capacity between ze o flow and cataloged capacities.

Hospital Applications

PrecisionCell filters are the preferred selection for hospital systems where code or good practice require that the filters be down tream of coils.

Gasketed Headers

PrecisionCell headered filters installed in Flanders K-Trac Filter Framing Modules or Sureseal Side Access Housings require gaskets on opposite head- er sides to prevent ir bypass.

To specify filters with g sketed headers, add suffix “S” to “H” to the model number as follows:

Model Number - S: Gaskets are on the sides paral- lel to t e separators.

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