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.
