Felt Bag Materials
Constructed using 100% synthetic fibers in polypropylene, polyester, Nomex® and Teflon®. The proper combination of fiber diameters, weights and thicknesses result in an economical depth filter media. To reduce fiber migration, Polypropylene bags are treated with a glazed finish, while Polyester and Nomex® bags are singed
- Polypropylene and Polyester materials meet FDA regulations forfood contact under CFR21, Section 177.1520
- Silicone-free construction
- High dirt holding capacity
- Ability to remove both solid and gelatinous particles
- Lowcost
- Glazed/singed finish on Polypropylene & Polyester reduces fiber-shedding
Felt Bag Styles
Steel-ring bags have a galvanized steel ring (stainless steel optional) sewn into the top of the bag. They are supplied with sewn seams standard. Plastic flange bags have a specially-designed flange sewn to the top of the bag. They are supplied with sewn seams standard (fully-welded seams available upon request).
Welded Construction
Fully-welded bags are available in polypropylene and polyester felt for #1, #2, #3, #4 and #5 plastic flanges.
- No needle holes, thus increasing efficiencies by preventing by-pass
- Elimination of threads further reduces possibility of fiber-shedding
