There are three main types of filter materials commonly used in dust removal filter cartridges:
Polyester non-woven fabric filter cartridge
Polyester fiber non-woven fabric can be coated with film, oil resistant, waterproof, and anti-static treatment. The dust removal filter cartridge made of this material has high filtration accuracy and is slightly more expensive than wood pulp paper. Polyester non-woven fabric filter cartridges are also used in environments below 100 degrees Celsius, but unlike wood pulp paper filter cartridges, polyester non-woven fabric filter cartridges can be used in humid environments and even washed with water, making them the choice for many vacuum pump dust filters.
Performance characteristics:
1. Anti static polyester non-woven fabric: Anti static, also known as anti static film treatment, is a layer of extremely thin conductive and breathable metal aluminum coating covering the surface of the filter material to prevent static electricity from sparking. It is suitable for metal dust filtration and explosion-proof dust removal.
2. Oil resistant and waterproof polyester non-woven fabric: Oil resistant, waterproof, and dustproof treatment is to cover the filter material fibers with a layer of fluororesin, making the filter material resistant to oil and dirt. Dust is not easy to adhere, and it is easier to blow back and clean dust. It is suitable for humid or oily environments with high dust concentration.
3. Ordinary polyester non-woven fabric: made of polyester fiber material, with a filtration accuracy generally above 5um, suitable for industries such as powder spraying, sandblasting, pigments, wood, cement, etc.
4. Coated polyester non-woven fabric: using imported FTE coated polyester filter material, the filtration accuracy can reach 3um, with small pore size, high porosity, smooth surface, waterproof, oil resistant performance, good non adhesiveness, chemical corrosion resistance, and high operating temperature. The filter made of this material has a long service life, and the surface filtration can be easily completed in an instant when the pulse is blown back to clear the dust, improving the filtration efficiency.
Scope of application: Welding dust removal, shot blasting manufacturing, pharmaceuticals, cement, tobacco, textile industry and other industries
Wood pulp fiber paper filter cartridge
The dust removal filter made of this material has a large dust holding capacity and is relatively affordable in price. Usually, wood pulp paper filter cartridges can only be used in environments below 100 degrees Celsius and need to be kept dry.
Performance characteristics:
1. Adopting the latest wave bending technology, the spacing between folds is uniform.
2. The adhesive will not produce delamination or cracking.
3. Low hardness and high-strength rubber sealing rings will not fall off due to working strength while ensuring sealing performance.
4. The end caps and inner and outer protective nets of the filter cartridge are made of stainless steel material, which not only has good strength, but also has good anti rust and anti-corrosion properties.
5. The wood pulp fiber paper dust removal filter cartridge is made of high-quality wood pulp fiber material, which not only has the characteristics of small pore size, high air permeability, low resistance, and high efficiency.
Scope of application: Powder recovery system for inlet filtration and powder coating lines of gas turbines, centrifugal air compressors, and other large units
Stainless steel filter cartridge
According to the requirements for material anti dwarfing ability, there are two types of parts to choose from: 304 and 3161, with commonly used accuracies of 30um and 500um. It can be used in high temperature environments around 200 degrees or corrosive environments.
Stainless steel filter cartridges can be repeatedly cleaned and used, but the cost of use is high and the filtration accuracy is relatively low.
