Baghouse America manufactures dust collector bags with all different fabrics for your application. Our main staple are fiberglass filter bags for industrial boilers applications. Our experience in this industry has proven vital for companies and their operations. Other fabrics include: ryton, pps, p84, polyester, nomex, aramid, acrylic, basalt, light fiberglass, woven fiberglass, woven texturized fiberglass, etc., We also treat our bags with PTFE, oliophobic, antis-tatic, and other treatments depending on the application.
Fabric filter bags (sometimes referred to as envelopes) are oval or round tubes, typically 15–30 feet and 5 to 12 inches in diameter, made of woven or felted material. Depending on chemical and/or moisture content of the gas stream, its temperature, and other conditions, bags may be constructed out of cotton, nylon, polyester, fiberglass or other materials.
Nonwoven materials are either felted or membrane. Non-woven materials are attached to a woven backing (scrim). Felted filters contain randomly placed fibers supported by a woven backing material (scrim). In a membrane filter, a thin, porous membrane is bound to the scrim. High energy cleaning techniques such as pulse jet require felted fabrics.
Woven filters have a definite repeated pattern. Low energy cleaning methods such as shaking or reverse air allow for woven filters. Various weaving patterns such as plain weave, twill weave, or sateen weave, increase or decrease the amount of space between individual fibers. The size of the space affects the strength and permeability of the fabric. A tighter weave corresponds with low permeability and, therefore, more efficient capture of fine particles.
Reverse air bags have anti-collapse rings sewn into them to prevent pancaking when cleaning energy is applied. Pulse jet filter bags are supported by a metal cage, which keeps the fabric taut. To lengthen the life of dust collector filter bags, a thin layer of PTFE (teflon) membrane may be adhered to the filtering side of the fabric, keeping dust particles from becoming embedded in the filter media fibers.
Some baghouses use pleated cartridge filters, similar to what is found in home air filtration systems. If you are not sure which baghouse filter bags you need, we can help. Contact us to learn more!
