WFB Filter bags, nominal

WFB Filter bags with PP collar ring or welded stainless steel rings are manu-factured in four different sizes. The available filter materials: polypropylene felt, polyester felt or nylon mesh enable the selection of a filter bag suitable in regard to temperature and chemical resistance. All seams of the WFB filter bagsmade of polypropylene and polyester are 100% ultrasonic welded. The seams of the filter bags made of nylon mesh are bordered with a nylon band and sewn with nylon yarn, however in the version containing a PP collar ring seal they are also ultrasonically welded along the collar ring. The filter surfaces of the WFBfilter bags are 0.05 m2 for size 3, 0.1 m2 for size 4, 0.25 m2 for size 1 and 0.5 m2 for size 2.

New, improved collar seal ring with additional, soft sealing lip on the top andwith the unchanged, proven sealing towards the restrainer basket on the bottom.
