1-5 Replacement bag PP felt filter bag stock supply
3F’s (polypropylene) PP liquid filter bag replacement made from our self-produced pp felt. Therefore, from PP particles to PP felt to PP filter bag, quality at every step is under our control.
As for the present technology and quality in polypropylene liquid filter bag manufacturing, 3F has 100% confidence to provide marketplace the best one. We creatively solved two common problems which happens frequently in previous industry application cases. The first one is leaking from the O-ring place, by using our PP filter bag, customers do not need to worry about this point anymore. The second is bag-exploding caused by quick pulse pressure arising inside filter housing due to poor felt flow rate, we solved the problem not from polypropylene filter bag itself but from its raw material, since we make PP filtering felt, so only 3F can control its quality as a whole.
Product Details

Comparing with other common O-rings, the edge of O-ring has its up forward arc and a ditch on the opposite face which can fit filter housing hermetically.

After singeing and press polishing, keep surfaces inside and outsider smooth, without fiber dropping in filtration.

Neat sewing & welding edge from standardized production line, keep our PP liquid filter bag quality stable.

Grid-type welding edge is more pressure-resisted than traditional parallel-type edge.
