Constructed using 100% Synthetic fibers in Polyester. The proper combination of fiber diameters, weights and thicknesses result in an economical depth filter media.


Fully welded felt bags are available in Polyester Felt for #1, #2, #3, #4 and #5 Plastic Flanges. There are no needle holes, thus increasing efficiencies by preventing bypass. The elimination of threads further reduces possibility of fiber shedding. 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. The Plastic Flange Bags have a specially designed flange sewn to the top of the bag. They are supplied with sewn seams standard (fully welded upon request).
