Filtration Designs bag separators

Tubular filter bag separators are the most prevalent type of filtration separators. Standard models have sock-like inverted filter bags that are cleaned after system shutdown. (For in-progress cleaning, see Jet-Clean filter separators below.) A properly sized filter bag separator downstream from a centrifugal type traps over 99% of the remaining solids, even with difficult powdered materials such as toner powder and paint pigments. A great virtue of Spencer filter bags is the broad selection of bag materials, including cotton sateen weave, cotton twill weave, polyester, nylon, polypropylene PTFE membrane over polyester and Nomex. Also, various fabric finishes and static electricity reduction types are available. It's important to offer many fabric choices because there is no such thing as standard dirt." The selection of filter media and filtration methods can be extremely demanding, involving hundreds of variables, but with Spencer's fabric choices and , it's easy to get the required filtration performance or chemical resistance. For example, acid fumes that attack polyester do not degrade polypropylene. Water vapor levels that make filtration difficult with cotton media do not affect synthetics like polyester. Tubular filter bag separators are available with a removable dirt can, hopper bottom with legs or various hopper bottom designs with mounting pads and frames for positioning over customer-provided drums, bins or trash containers. A large selection of accessories and convenience devices is available for any separator, including various manual or automated material discharge valves, gauges, volume measurement devices, abrasion-resistant components, etc. Spencer's Jet-Clean separators utilize either a filter bag and cage assembly or disposable pleated filter cartridges of various non-woven media that, again, can be chosen for specific performance properties or their chemical resistance ratings. Jet-Clean separators utilize periodic air jet cleaning of the filters. Cleaning is sequential, so some filters continue working while others are being cleaned. The Jet-Clean design adds flexibility to allow continuous filter cleaning during non-stop processes. These separators are also available with removable dirt cans, hopper bottoms with legs or hopper bottoms with frame mounting
