  • Fully-welded construction with patented SENTINEL® seal ring provides 100% bypass-free filtration and better performance for critical applications
  • The pressure-activated SENTINEL seal ring provides a flexible, chemically resistant seal which adapts to any bag filter housing
  • The specially developed media structure provides a long operating life as well as absolute filtration
  • The structure of the filter material consists of up to twelve layers of a medium that gets finer and finer from one layer to the next
  • The 100% polypropylene design stands for "silicone-free" materials combined in an economical and easily disposable filter bag
  • PROGAF filter bags are made from the finest hydrophobic polypropylene fibers that require wetting with an aqueous solution (detailed instructions for use are included in every box of PROGAF filter bags)
  • 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

PROGAF filter bags constitute a new, high-performance alternative for applications requiring absolute filtration. The multistage filtration, with filter material that gets finer from layer to layer, provides optimum efficiency (greater than 99.9%) and a long operating life.
