Shaker, Reverse Air Pulse Jet We offer a complete line of replacement and custom designed dust collector bags to fit most manufactures' filter bag housings. Our filter bags are carefully fabricated and sized to ensure ease of installation and change-out. These Filter bags are designed to be mounted and gasketed firmly into place with a snap band, corded cuff, or clamp to ensure a dust tight seal. Various coatings and finishes can be applied to either side of the dust collector bag to enhance cleaning and efficiencies, as well as prolonging service life. Groundwire, anti-collapse rings and other options can be easily incorporated into bag construction. We can custom fabricate various types of attachments to work with your specific shaker mechanism, whether it's a loop, eyelet, grommet or other device.   We Can CUSTOM FABRICATE Any Style Bag to Meet YOUR SPECIFIC NEEDS   Designed for ease of installation and change-out Wide range of coatings and finishes Wide variety of paper, felt and woven filter medias Custom designed bags What we need to know to provide you a quote: 1. Brand name of the Collector. 2. Is it a Shaker or Pulse style? 3. Length of Bag or Cage. 4. Diameter. 5. Flat Dimension. 6. Specs on Material. 7. Is it a Top or Bottom Load Collector? Chemical Felt Treatments Reliable Filter now has the capability to apply a complete variety of chemical treatments to its range of filtration felt media. The ability to apply these finishes can considerably improve a felts performance, efficiency, and life expectancy. Treatments can be applied either by impregnation, where all the fibers are individually treated, or by coating, where only the filtration surface of the felt is treated. Also a combination of impregnation and coating can be done. "Othephobic" "Hydrophobic" TD This treatment is applied via an impregnation process to impart some water or oil repellancy properties to the filter media. Every fiber is treated with a fluorocarbon based resin which assists in releasing a wet, oily or sticky dust cake during cleaning. Another, very common use for a felt with a fluorocarbon treatment is in applications where there is a high risk of hydrolysis attack. This is generally caused by the baghouse temperature falling below the dewpoint temperature (temperature at which the gas condenses into a liquid). Here the treatment provides some chemical resistance. "Silicone" SL This is also an impregnation treatment which is applied to all the fibers. The presence of the silicone considerably reduces any cake cleaning problems associated with sticky, agglomerating dusts. Usually, a silicone treatment is less expensive than fluorocarbon. "Acid Resistance" AR Polyester and Aramid fibers are susceptible to attack by moisture particularly in the presence of acids. This is an impregnation treatment that "sheaths" every fiber in a chemically inert fluorocarbon resin that retards the destructive chemical attack on the fiber, the result being an increase in product life. "Flame Retardant" FR The design of some filter systems can cause hot incandescent particles to be carried in the dust stream over to the baghouse and onto the filter bag. In extreme circumstances these particles can ignite the media and cause a fire in the baghouse. More commonly, they cause minor damage such as pinholes, which leads to excessive emissions and premature bag failure. This treatment is applied via impregnation and each fiber is individually protected against the hot particles, hence prolonging bag life. "Acrylic Foam (CAC) Coating" SB This is a coating of porous acrylic foam which is applied to the felt surface to effectively simulate an instant dust cake. Via effective control of the foam cell "bubble" structure a very uniform pore structure is applied to the filtration surface. The benefits of this type of coating include improved filtration on the felt surface as well as improved filtration efficiencies without incurring increased filter pressure drop. "Dura-Shield" (CPU) Evaluating This is a special new polyurethane foam coating applied exactly the same as the acrylic coating, giving similar performance attributes. However, the Dura-Shield coating also imparts improved temperature resistance and coating toughness properties over the acrylic product. "PRFE Foam (CTF) Coating" TF This is a micro-porous surface coating of a PTFE based foamable resin. The PTFE coating imparts two distinctive advantages. Firstly, the coating improves the surface filtration efficiency; and secondly, the PTFE resin reduces cake build-up of agglomerating, strongly adhesive "tacky" dusts. This enhances cleanability and reduces the risk of premature blinding of the filter.
