Extended Media Separator Type Rigid Filters

UL Class 1, Std & Hi Cap: 8*055.xxxxxxx1, 87*55.xxxxxx1 UL Class 2, Std & Hi Cap: 8*055.xxxxxx, 87*55.xxxxxx (Insert 6 for 65%, 8 for 85%, 9 for 95% ASHRAE Effici ncy)

General

PrecisionCell extended media separator type rigid filters are designed for use in most commercial or industrial HVAC systems where medium to high effi- ciency filtration is required. PrecisionCell filters are available in average efficiency ranges of 60-65%, 80-85% and 90-95% per ASHRAE Standard 52.1 test methods and are available in standard and high capacity versions.

These filters are suitable for variable air volume sys- tems. Operating face velocity ranges are from 0 to 625 FPM for 12” deep filters. Three styles are avail- able: box, single and double header. PrecisionCell filters are UL 900 Class 1 listed.

Installation Considerations

PrecisionCell rigid filters may be installed in Flanders Type 9 Holding Frames, K-Trac Filter Framing Modules, Sureseal Side Access Housings, or in similar existing hardware.

Type 9 Holding Frames are riveted together to form a bank and may be installed for upstream or down- stream service. K-Trac Filter Framing Modules are especially suitable for medium to large built-up filter banks. Smaller systems and systems with minimum upstream access space are best served using Sureseal Side Access Housings.

The single header version should be selected for use with hardware framing sys ems and side access housings. If the filter is installed so hat it protrudes upstream of the Type 9 Holding Frame, the double header filter is required.

Construction Options

PrecisionCell filters are designed for temperatures up to 350 degrees F hrenheit For high temperature or gas turbine models, see PrecisionCell GT and HT bulletins.
