Process filtration
Liquid filter bags
Filter bags for liquid filter housings, in needle-felt or monofilament media.
A liquid filter bag is quick to change and is sized by the standard housing size. Needle-felt filters in depth and holds more load; monofilament filters at the surface, rinses clean and holds a more consistent rating.
