Porous Metal Felt Filter Elements Announced
(April 15, 2010) Swift Filters, Inc. has announced a new series of metal
felt filter elements. The elements employ filter media made of thin filaments of nonwoven stainless steel, which is ideal for high pressure, highly corrosive, highly viscous or radioactive applications. The metal felt employed is highly porous (up to 85%) providing very high flow rates of up to 20 times those of other media types as well as exceptionally long life.
Random fiber filtration (metal felt) can provide absolute particle retention, longer on-stream time and high dirt-holding capacity for under 60 micron filter elements. Although more expensive, it often offers clear advantages over wire cloth, sintered metal or non-metallic fibers. Its high temperature, high pressure and corrosion resistance combined with almost unending cleanability, make it highly economical for hostile environments.
Metal felt filter elements are often found in demanding applications such as chemical and catalyst recovery, polymer filtration, aerospace, medical and pharmaceutical, nuclear venting, food and beverage and refinery uses.
