Filter material is synthetic glass fiber, its dust capacity is large, long service cycle, mostly used for air filtration.

Features of replaceable primary filter:

1. Filtration efficiency for particles >5.0um is 40%~60%;

2. Special bulk type high-flux and low-resistance chemical fiber cloth is used as filter material, with large dust capacity;

3, galvanized steel plate, aluminum alloy frame;

4, the outer frame adopts detachable design, convenient replacement of filter material to achieve the purpose of frame reuse; ;

5, polyester synthetic fiber filter material, low initial resistance;
