In the chemical processing industry, bag-type strainers are widely used. They can handle a wide range of flow rates and can be built out of nearly any material to withstand chemical attack, extreme temperatures, and high pressures to retain small particles.
Process Equipment Corporation produces a variety of bag filters. Liquid filter bags and dust collector bags are the most common applications for industrial bag filters. We make both, but we'll focus on the liquid filter bags here. Please look up the same dust collector bags and systems if you have a requirement for bag type strainer.
Liquid bag filters have a wide application in the chemical industry. These could be used as a pre-filter to remove larger dirt particles before using bag or cartridge filters for fine filtration. These could be used to polish edible oil or paint filters. Bag filters can be simplex or duplex, single bag or multi-bag, depending on the process. Also available are bag filter housings made of MS, SS 304, SS 316, SS 316L, and other materials.
