Filter material according to different density, thickness and fiber to the fabric, diversity, gradually layer way sex, rolling acupuncture is made
Should gradually close type structure according to the dust particles size, is blocked in the level of different density, let large amount of dust
Should some wind speed can still keep original shape, growth of filter life, reducing replacement cost
Should the inside and outside of high and low melting point, fiber composite fiber to be made between contact firm, combined with close, and it is not easy to fall off
Should have the viscous filter cotton (stereo spray adhesive processing), half viscous (surface spray adhesive processing), non-viscous (without glue) to choose from
Graduate from professional galvanized steel box can be mounted to the aluminum alloy frame, can also add or metal, can effectively support back nets air filter to bear large is out of shape not easily
