The polypropylene or polyester needle felt construction of the DURAGAF extended-life filter bags, along with the increased thickness of the filter material, significantly increases the dirtholding capacity and extends the lifetime by two to five times longer than standard needle felt filterbags. These features significantly reduce operating costs. In addition, the needle felt material with smaller diameter fibers also provides a more porous filter material while maintaining the same low initial differential pressure.

Needle felt


  • The reinforced filter material thickness facilitates gel removal
  • Lower operating costs due to extended lifetime
  • DURAGAF filter bags are available in PEXLF and POXLF materials and comply with FDA and EC directives and regulations for food contact
  • Special surface treatment significantly reduces fiber migration 
  • Material is free from silicone and crater-forming substances
  • Fully-welded construction with patented SENTINEL seal ring provides 100% bypass-free filtration
  • The pressure-activated SENTINEL seal ring provides a flexible, chemically resistant seal which adapts to any bag filter housing
  • Eaton strongly recommends the use of an insertion tool that facilitates the insertion of the filter bag into the bag filter housing and ensures the correct alignment of the filter bag inside the restrainer basket
