AW Filter Regulator

Filtration efficiency is high, generally reaching 99.99%; at the same time, it reduces air resistance, ensures the filtered air pressure, and keeps flow variation small. The structure of the self-cleaning filter must not only withstand the corresponding pressure but also have good sealing performance. To ensure the filtration effect, the filter material must have a certain impact resistance, withstand a certain pressure, and withstand impact; during operation it will not crack, pill, slough, oxidize, or shed from the surface.

Depending on the filter material, it can be classified as "depth", "mesh", or a depth-mesh combination type.

The "depth" filter element is mainly composed of coarse fibers, calcined powder, and porous ceramics, etc. When a cyclone occurs, it forms a curved passage that facilitates capturing dust particles in the cyclone.

In the customized air-source filter pressure reducing valve, the screen-type filter element is made of porous metal, plastic, various fiber materials, micro-porous membranes, etc. This filter material has a uniform pore-size distribution and high porosity, and can filter any dust particles larger than the pores. For example, filters made of ultra-fine glass fiber fabric or polyester fiber weaving can filter dust particles above 0.9 microns.
