Divided by thickness mainly has: 5MM, 10MM, 15MM, 20MM and so on
Resistance: less than or equal to 50 Pa (wind speed: 1.0 M/S), filter efficiency of 2.0 micrometers (%): more than or equal to 50 %( wind speed: 1.0 M/S)
Primary efficiency filter cotton is used on the front end of the filter which can eliminate fiber dust, willow, and sand, cleaning dust and some other more than 5 micrometers larger particles, so as to protect the latter part of the filter.
