What is a foam filter?

What is a sponge filter and how does it work?

Foam filters are air cleaner filters that use polyurethane foam elements as the filtering material to trap unwanted air contaminants and particulates. Foam filters are made up of tiny interlocking cells that prevent the passage of dirt particles and distribute these throughout the entire volume of the foam. Foam materials are used in many performance air filters for engines on appliances such as lawnmowers, power tools and other power equipment.

Filter foam is an open-cell polyether/polyester-based polyurethane foam and has many uses. Filter foams usually differ in pore size and the number of pores per inch (PPI).

Applications

• 
  

• Filter Applications: Small engines, air compressors, hair dryers, face masks, vacuum cleaners, air conditioning, school and motel ventilators, oil-mist eliminators, automotive air cleaners, industrial panels, electric equipment, projector equipment and dust bag collectors.

• Coalescing: Separation of water from gasoline, perchlorethylene and jet fuel.

• Noise Suppression: Microwave covers, aircraft, industrial vacuum cleaners, high intensity sounds.

• Miscellaneous: Powder puffs, floor scrubbing pads, filters in hydraulic lines, lint-free wipers, pre-filter for liquid filter, paint brush applicators, blackboard erasers and foundation for ceramic and metallized high-tech filters.

Features

Our high-capacity foam filters dust, allergens and other debris from central heating and air conditioning systems while maintaining airflow around the captured particles. It is also used as speaker foam due to the high air-flow its structure allows.

Note: This foam is dark charcoal.

Details

Characteristics: A reticulated, open-pore, flexible, ether-type of polyurethane foam. Characterized by a skeletal structure of strands which provide a constant 97 percent void space and a very high degree of permeability.
