Reticulated Polyurethane Foam

The foam filter used in the plastic fan filter assemblies is ideal for many filtration applications. It is completely safe to handle. It is non-allergenic, non-toxic and resistant to most common detergents and solvents.

Thickness
The foam media used in the fan filter assembly is approximately 3/32” thick and is tough enough for frequent handling or washing. This media is designated as “A” when ordering.
Bulk foam is also available. See below.

Flammability Classification
The foam filter media used in the plastic fan filter assemblies are rated with a 900 testing, Class 2.

Poly/Cotton Fiber Media

Another choice for particulate filtration is the non-woven fiber media designated as “B”. It is a blend of polyester and cotton fibers that have been chemically bonded with ethylene vinyl chloride/poly vinyl acetate. The filter media provides excellent filtration and the air pressure drop will vary with size of filter and rate of CFM. This media is available on the FF 60, 80, 92, 120 and 127 mm fan filter assemblies. (Not available on the FF-SC series.) It is rated as Class 2.

Aluminum Screen Mesh

When no particulate filtration is required, a screen wire can be used in the fan filter assembly that will allow maximum air flow. The 1618 screen wire is the most porous. The 3030 screen wire provides some filtration of larger particulates such as lint. The screen wire is easily cleaned with water and/or detergents. (Not available on FF-SC series.)

Filter foam is UL Rated 900 Class 2
