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;

Also can be used in air purifier system.

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 flat pre air filter frame is aluminum alloy ( 21mm, 46mm thickness ) or galvanized steel ( 46mm thickness ), for some high temperature, acid and alkali environment, the frame is SUS stainless steel; Aluminum alloy frame also available; Filter media is glass fiber roll for painting industries, and HT environment;

The service life for flat pre air filter is about 3-5 months, pleaes check the filter media, if it`s getting dark, it`s the time to replace it or wash it.
