Filter cartridge, as the name suggests, is a kind of cartridge used for filtering pieces, generally divided into filter gas medium filter cartridge and filter liquid medium filter cartridge, usually, we refer to the filter cartridge is mostly used to filter gas, called air filter cartridge (hereinafter referred to as filter cartridge). The filter cartridge is a surface filter element, which USES the tiny breathable tissue formed on the surface of the filter material to block the granular material in the gas.
Classification of cartridge
Common filter cartridge filter materials are wood pulp fiber filter paper, polyester fiber non-woven cloth. Polyester fiber non-woven cloth can be coated, oil-proof, waterproof, anti-static treatment.
Ordinary polyester non-woven fabric: made of polyester fiber material, the filtering precision is generally above 5 μm, applicable to powder spraying, sandblasting, pigment, wood, cement, and other industries filtering.
Coated polyester non-woven cloth: PTFE filter film and polyester non-woven cloth heat composite. The filter cartridge made of this material has a long service life, high filtration accuracy, and it is easier to blowback the ash, which can reach 1-2 years under general working conditions. Scope of application: welding dust removal, shot peening, pharmaceutical, cement, tobacco, textile industry, and other industries filtration.
Anti-static polyester non-woven cloth: anti-static, that is, anti-static film treatment, is to cover the surface of the filter material with a very thin conductive and breathable metal aluminum coating, to avoid static jumping fire, suitable for metal dust filtration, explosion-proof working condition dust removal.
Oil-proof and water-proof polyester non-woven cloth: Oil-proof, water-proof, and dust-proof treatment is to cover a layer of fluorine resin on the filter fiber so that the filter material has the function of oil-proof and anti-fouling, dust is not easy to stick, back-blowing and dust cleaning is easier, suitable for humid or greasy environment with high dust concentration.
Wood pulp fiber compound filter paper: suitable for gas turbine, press plastic machine, sandblasting, tobacco, coal dust, drift dust, and other industries filtration.
Polyester non-woven coated filter material is the core raw material of industrial dust removal filter cartridge and industrial dust removal filter bag, with good compound rate fastness, reusable, pulse dust removal effect, high-cost performance!
1) Adopting unique paste extruding and bidirectional stretching technology, the fiber diameter can reach less than 100nm, which has the characteristics of high efficiency and low resistance.
2) Pure physical filtration mechanism, long-term storage efficiency will not decrease, safe and reliable; After boiling water or alcohol disinfection and sterilization, the efficiency will not decline and can be reused.
3) The three-layer structure polytetrafluoroethylene nano-filter obtained by the combination of PTFE nano-pore film and the upper and lower two layers of non-woven cloth has obvious advantages, such as lower resistance, higher efficiency, and less risk of damage during post-processing and use, compared with the common two-layer structure filter.
4) It can completely block non-oily and oily particles, with over 99% protection effect on droplet, dust, aerosol, bacteria and virus, and low respiratory resistance.
