According to clients` requirements offer different specifications

Applications:

For primary filter in HVAC system, AHU system, Fresh air system, enlarget the service life of next stage filter like pocket filter, V bank filter, HEPA filter and so on;

Description:

the galvanized steel frame pre air filter are tested according to EN:779 standard;

filter efficiency is G3 or G4;

Gravimetric: 80-90%;

Normally there is no gasket, but we can add EVA ( Neoprene ) if required.

For reducing the running budget of HVAC system or air conditioning system, it`s necessary to change the pre air filter in time; Normally, it`s 3 months to change it per time. Also, the frquency of changing depends on the using environment. Change the pre air filter can also enlarge the service life of HEPA filter;

The pre filter frame is galvanized steel, for some high temperature, acid and alkali environment, the frame is SUS stainless steel; Aluminum alloy frame also available;

If the pre air fitler media become black, it`s the time to replace it; some people like to wash it and use it again, we don`t recommand that; if the filter frame is metal, that can be washable, if it`s paper, it`s disposable.
