This series mainly absorbs the larger particles to prevent the early ceiling filter block, it is made from hardened fiber and is covered with glue for hardening and stabilizing the fiber, the hardness and density are better than the same kinds of products, the primary filtration efficiency and the air flow rate have been increased.
Hardened primary filter(blue & white)
This series is made of prolonged and hardened fiber, it is sprayed with special blue glue. The blue glue is able to show the use life directly, when the blue part being covered with dust totally, the filter must be replaced.
Air Flow Rate:2160m3/h
Filtration Class:G2(DIN 24185)
