Reticulated Polyurethane Foam

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

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 isdesignated 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 witha 900 testing, Class 2.

Poly/Cotton Fiber Media

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

Aluminum Screen Mesh

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

Filter foam is ULRated 900 Class 2
