UNIBAG filter bags provide the value and reliability of a high performance filter bag seal in a fully-welded construction with the economy of a typical sewn filter bag. They are manufactured from needle felt material in polypropylene and polyester and comply with the industry standard for bypass-free filter bag construction.

Needle felt


  • Fully-welded construction with UNIRING seal ring provides 100% bypass-free filtration
  • Polypropylene seal ring provides a chemically resistant seal which adapts to any bag filter housing
  • Polyester seal ring is durable for higher temperatures
  • 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
  • All material has passed Eaton‘s rigorous Engineering Standard testing criteria for acceptability
  • Material is free from silicone and crater-forming substances
  • 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
