According to the function and role, the general general air filter can be divided into initial effect filter, medium effect filter and sub-high efficiency filter. Among them, the primary effect filter is mainly suitable for the primary filter of commercial or industrial ventilation and air conditioning system or the pre-filter of clean room ventilation and air conditioning system, which can filter dust particles with a particle size of more than 5μm.
The performance characteristics of air filters mainly include the following six:
(1) High filtration accuracy, uniform filter element aperture;
(2) Small filtration resistance, large flux, strong pollution interception ability, long service life;
(3) The filter material has high cleanliness and no pollution to the filter medium;
(4) Acid, alkali and other chemical solvents;
(5) High strength, high temperature resistance, the filter element is not easy to deform;
(6) Low price, low operating cost, easy to clean, and the filter element can be replaced
