APPLICATION
The F25 Media Air Cleaner captures a significant amount of the air-borne particles from the air circulated through the unit.
F25F
Media Air Cleaner
PRODUCT DATA
FEATURES
•High efficiency media filter captures particles as small as 1.0 micron.
•Efficiency and arrestance ratings based on the American Society of Heating, Refrigerating and Air Conditioning Engineers Standard 52-76.
•Applicable to all gas, oil, and electric forced warm air furnaces and to compressor cooling up to 3-1/2 tons. Can be used with heat pumps only if the filter is changed regularly to prevent excessive pressure drop. Not recommended for applications where pressure drop may be critical.
•Mounts in the return air duct.
•Cabinet can support weight of residential furnace and evaporator coil.
•Requires no electrical connections.
•Mounts in any position.
•Requires no maintenance except periodic media filter replacement.
•Media filter is easily replaced by homeowner.

F25F MEDIA AIR CLEANER
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:
F25 Media Air Cleaner includes cabinet, access door and pleated media filter.
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. Not recommended for applications where pressure drop may be critical.
Arrestance Efficiency:
Efficiency ratings are based on National Bureau of Standards Dust Spot Method using atmospheric dust and American Society of Heating, Refrigerating and AirConditioning Engineers Standard 52-76.
Initial Efficiency: 10 percent (staining dirt removal). Average Efficiency: 18 percent (staining dirt removal). Average Arrestance: 90 percent (bulb dirt removal).
The F25F removes particles as small as one micron. See Fig. 1 for size ranges of common household particles.
Filter Media:
Nonwoven, reinforced cotton and synthetic fabric, pleated for greater media area. See Table 1.
Capacity And Pressure Drop:
See Table 1.
Temperature Rating:
-40° to +125°F (-40° to +52°C).
Dimensions:
See Fig. 1.
Mounting:
Mounts in any position in the return air duct next to the furnace blower compartment. Air flow must be in the direction of the arrow on the filter cartridge. Cabinet is sturdy enough to support weight of a residential furnace and evaporator coil.
Underwriters Laboratories, Inc.:
Listed to UL 900, Class 2.

Upgrade Path:
The F25 uses the same cabinet as the F50 Electronic Air Cleaner. Upgrade requires installing the cell key, electronic cells, protective screens and installation and wiring of the power box.
Accessory:
S830A Clogged Filter Indicator.
Replacement Media:
Replace media filter annually or more often if reduced air flow results in lower heating/cooling equipment performance.
