Bag Filter

Ultra-Bag fully welded filter bags come in a variety of needle felt materials: polypropylene (PP), Polyester (PE) and Nylon (NMO).

All seams are welded, rather than sewn, and combined with our positive sealing cast bypass free (polypropylene or polyester) welded rings, no process liquid can bypass through the needle holes. Our monofilament mesh bags are constructed of individual, twisted threads are woven with evenly distributed holes for better strength, perfectly suitable for accurate screening, straining and classify.

Bag filters can allow particles between 1 to 1200 microns to get through the filter and there are many choices in between, it depends on what liquid you should filter.

All our bags are available with plastic collar, or with stainless steel ring.
