Application Guidelines

Precision Pak filters should be selected using 24” x 12” face sizes. This allows for 12” increments in height and width of the filter bank and insures that replacement filters will be readily available.

Housings require polyfoamgaskets on opposite header sides to prevent air bypass. To specify Precision Pak filters with gasketed headers, add suffix ”S” or “H” to the model number.

Precision Pak filters should be installed with pockets vertical wherever possible. It is acceptable to install 24” x 12” face size filters with pockets horizontal if necessary to meet the size requirements of the filter banks.

Prefilters

Properly selected bag filters without prefilters will generally require changeout annually in typical HVAC applications. Because of the frequent main- tenance expense and in rease in fan kW input using prefilters, they are often re ommended with 85% and 95% efficient Precision Pak final filters. However, the energy cost to operate a prefilter sel- dom warrants their use with 55% or 65% filters.
