Because standard filter bags are hard to change and retain too much liquid, consider the Eaton HAYFLOW filter. This filter has a convenient cartridge design that makes changeouts simple. The Polypropylene Extended Life felt lasts five times longer than standard filter bags. The Polypropylene SENTINEL seal ring makes the HAYFLOW useful in many applications. This filter is size 2 and will fit in standard filter bag housings, so retrofitting is easy. This product has a Micron Rating of 10 and is sold in box quantities of 8.
