Which a few kinds air filter can be divided into? F5、F6吗?

Air filter is divided into the early effect filter, in effect filter, filter, etc. , * * * * * * level of filtration efficiency of F7 to cover the H10, has big filter area, capacity of large amount of dust, low resistance, long service life, the characteristics of wide applicable scope. Structure: the casing outside the metal ( Flanged) Or offset paper, aluminum foil have partition, effective sealing glue sealing. Note: according to customer requirements production F5、F6 F7, F8, F9) For the filtration efficiency ( Colorimetric method) F5, F6 40 ~ 50% : 60 ~ 70% F7:75 ~ 85% F8:85 ~ 95% F9:99% air filter can absorb the dust and intercept tiny body and suspended in the air, USES the hot melt technology, from the structure, the performance is very stable, not easy to deformation or distortion occurs, it will reduce the risk of broken. In addition, the effect the characteristics of the filter also reflect on the air volume, effectively filter in the air volume is big, and let the amount of dust is quite high.
