How the Filter Bag Works:

In the bag filtration system, the filter bag is supported by an inside filter basket. Incoming fluid is filtered by the bag, and impurities are intercepted within the filter bag. After changing the filter bag, the filter system is ready for continued use. Bag filters are becoming a trend, partially replacing cartridge filters due to their ability to filter large amounts of liquid efficiently.

Paints and varnishes
