SPECIFICATIONS
IMPORTANT
The specifications in this publication do not include
normal manufacturing tolerances; therefore, an
individual unit may not exactly match the listed
specifications. This product is tested and calibrated
under closely controlled conditions, and some minor
differences in performance can be expected if those
conditions are changed.
Model:
F35F Expandapac Media Air Cleaner includes cabinet,
access door, Expandapac media filter, filter frame, and
combs.
Application:
Use with gas, oil, and electric forced warm air furnaces and
with compressor cooling. Can be used with heat pumps if
filter is changed regularly to prevent excessive pressure drop.
Arrestance Efficiency:
Efficiency ratings are based on National Bureau of Standards
Dust Spot Method using atmospheric dust and American
Society of Heating, Refrigerating and Air-Conditioning
Engineers Standard 52.1-92.
—Initial Atmospheric Dust Spot Efficiency: 25.8%
—Average Atmospheric Dust Spot Efficiency: 32.0%
—Average Synthetic Dust Weight Arrestance: 92.0%
—ASHRAE Dust Holding Capacity: 55g
The above data is for a 16 x 25 in. filter.
The F35F removes particles as small as 1.0 microns.
