  • 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
  • Material is free from silicone and crater-forming substances1
  • Special surface treatment significantly reduces fiber release
  • Stable and flexible welded seams that adapt to the restrainer basket
  • The handles in the ring make replacing the filter bag quick and easy
