POMF series is a polypropylene microfiber filter bag. It is a direct replacement for the FSI POMF series filter bags. As a perfect equivalent, their performance is very close. The POMF contains three layers: a pre-filtering layer that removes coarse debris; the primary layer, composed of micro pores (for efficient particle retention); and an outer cover that prevents fiber migration. The finish-free fibers are non-foaming, which is ideal for food, beverage, water, chemical and coating applications.
