Material: chemical fiber

The width of the primary filter cotton is mainly: 1250MM width, 1400MM

According to the thickness, there are mainly: 5MM thick, 10MM thick, 15MM thick, 20MM thick, etc.

Resistance: less than or equal to 50 Pa (wind speed 1.0 m/s), 2.0 micron filtration efficiency (%): greater than or equal to 50% (wind speed 1.0 m/s)

The primary effect filter cotton is used at the front end of the filter to remove fiber dust, poplar catkins, sand dust, sweeping dust, etc. Large particles larger than 5 microns are used to protect the rear filter, and the most frequent replacement It is recommended to change it every 3-5 days or once a week or according to the experience of on-site engineers.
