Primary Filter

Product Introduction：

The primary - effect filter is suitable for the primary filtration of air - conditioning systems and is mainly used to filter dust particles larger than 5μm. There are three types of primary - effect filters: panel - type, pleated - type, and bag - type. All types can be customized. The frame materials include paper frames, aluminum frames, and galvanized iron frames. The filter materials include non - woven fabric, nylon mesh, activated carbon filter media, metal perforated mesh, etc. The protective nets include double - side spray - painted wire mesh and double - side galvanized wire mesh.

1.Primary-effect Nylon Mesh Filter

Application:

Dust removal and filtration. It is generally used in fresh air units, air inlets and other places in contact with outside air, as well as on large - air - volume filtration equipment such as indoor air handling units. It is also suitable for ventilation and filtration in special places with acid, alkali or high - temperature environments. It can be used in household air conditioners and central air - conditioning systems.
