Sentinel Filter Bags

Sentinel filter bags are the industry standard "every day" filter bags for industrial applications. Unlike less expensive Snap-Ring and UniBag filter bags are made from a heavier material and are all made from a fully welded construction. The heavier material provides slightly more depth filtration, essentially a torturous path for the fluid and particles to navigate; the particles are retained and the liquid passes through.
The fully welded design increases the strength of the filter bag. The restrainer (support) basket relieves most of the weight stress from the filter bag, however the differential pressure stress will usually cause sewn seams to burst before welded seems would.
Sentinel filter bags are made in the widest number of materials and retentions and their universal #1 through #4 sizes will fit any brand of bag filter designed for #1 through #4 sizes. Sentinel filter bags also provide nominal retention efficiencies of 65% to 70%.
