More air filter area, more airflow rate
Synthetic fiber, G3 G4 Efficiency filter
G3 and G4 Efficiency Pleated pre air filter can effectively remove the dust in the air and maintain the cleanliness of the ventilation system. It can reduce the dust for the bag filter and increase its service life.
The frame can be made of metal or corrugated paper, which has relatively good strength. The metal frame filter can be washed 1-2 times.
If large air volume is required, the design of the metal skeleton can be adopted to maintain the strength of the filter
V-shaped filter material folding can effectively increase the filtering area and ensure the air volume and dust capacity
