Air Filter Media
A
diverse range of synthetic electrostatic media, both woven and
nonwoven, is used in filtration designs. Electrostatic air
filtration includes a combination of impingement and charged
particle attraction. Many synthetic media contain an inherent
electrostatic charge that won't wash out or diminish over time. The
electrostatic charge is enhanced by the friction of airflow over
the media surfaces. Synthetic media, like polyester and foam can be
impregnated with finely ground coatings such as activated carbon,
activated aluminum, potassium permanganate and antimicrobial.
Customized air filtration needs can be met by varying the
densities, layers and types of media depending on air flow
restrictions, arrestance efficiencies required and budget
parameters. Other types of air filter media like aluminum expanded
metal mesh and wire cloth are also available.
Metal pad stabilizing frames (as shown in the above photo) are available in a .02 gauge or heavy duty 24 gauge galvanized steel frame with expanded metal support grid on one side. This can be used in filtration applications involving media pad change outs. The frame is available with or without 2 criss crossed wire supports to hold the media in place.
