    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 for food contact under CFR21, Section 177.1520

    Silicone-free construction

    High dirt holding capacity

    Ability to remove both solid and gelatinous particles

    Low cost

    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
