Powder Coating  Filters

Powder Coating Filters are very important for powder booth maintenance. There are three basic types of powder coating filters for your powder coating system – powder cartridges, final filters, and pocket bag filters. Powder coating filters (powder cartridges) typically use an 80/20 cellulose paper/poly blend, or 100% spun-bond polyester media types. Powder coating filters (final filters) are used after the cartridge filter housings. The most popular types of powder coating filters (final filters) are usually 95% efficient. Powder coating filters (final filters) are usually available in box style, single header and double-header mounting variations.

Powder coating filters (pocket bag filters) in some operations are swept and vacuumed to prolong the powder coating filters’ (pocket bag filter) service life. FAQ’s regarding powder coating filters:
