WFB-1AP Filter bag, pleated

Single-layer pleated filter bag with NMO net support

WFB-1AP Filter bag, pleated

WFB-1AP Filter bags are supplied with a single-layer, pleated filter media made from polypropylene felt or Polyester felt. They are covered outside by a 300 micron NMO net support made from Nylonmonofilament.

WFB-1AP Filter bags are manufactured exclusively in size 1 and size 2 and, with their high pleats, show a filter surface area of 1.2 m², 2.5-times the filter surface area compared to common filter bags!

All components are carefully processed, the filter media is ultrasonic-welded at the collar ring seal and at the bottom. For safe sealing the WFB-1AP Filter bags come with our new improved collar seal ring with additional, soft sealing lip on the top and with the unchanged, proven sealing towards the restrainer basket on the bottom.

Like all our filter bags they own all important certificates for the contact with food, for industrial applications like paint and coatings or parts-cleaning-plants.

WFB-1AP Filter bags with single-layer pleats are designed to extend the filter life time and improve the filtrate quality compared to common filter bags.
