Three ear polyester anti-static dust removal air filter element

The three ear top polyester anti-static dust removal air filter element is a high-performance filtration product specially designed for industrial dust removal and air purification. It is made of imported polyester long fibers through spunbond technology, with a dense fiber structure and smooth surface, combining the two core advantages of high filtration efficiency and low operating resistance. The surface of the filter element has undergone special anti-static treatment, with a large surface resistivity of less than 10 ⁸ Ω, which can quickly dissipate the static electricity generated by friction and eliminate the risk of dust explosion caused by static electricity accumulation at the root. The filtering accuracy covers multiple levels ranging from 0.3 to 5 μ m, and the interception efficiency of submicron dust can reach over 99.9%. With a large dust holding capacity and long service life, it is an ideal choice for flammable and explosive dust working conditions and high cleanliness requirements.

The three ear top polyester anti-static dust removal air filter element adopts a three ear top installation structure design. The three symmetrically distributed ear buckles are precisely matched with the top installation interface of the dust collector. No tools are required during installation. Simply align with the card slot and screw it in to lock it. It can be replaced within 30 seconds by a single person, and the efficiency is more than 10 times higher than traditional bolt connections. The filter material adopts a wide fold folding process, with a number of folds ranging from 30 to 80, to maximize the filtering area in a limited space; The top end cover is made of galvanized steel plate with a thickness of ≥ 0.8mm, which is stamped and treated with spray rust prevention. The bonding area with the filter material is sealed with polyurethane foam adhesive to ensure zero air leakage. Some models are coated with PTFE microporous film, which has an extremely low surface friction coefficient. When combined with pulse back blowing for dust removal, dust is easily shed, and the growth curve of operating resistance is smooth, greatly reducing the energy consumption and dust removal frequency of the fan.

The three ear top polyester anti-static dust removal air filter element is widely used for dust control in metal cutting, polishing, shot blasting, sandblasting and other processes, organic dust and acid alkali mist filtration in the chemical industry, clean air guarantee in electronic manufacturing workshops, smoke removal in the building materials and cement industry, dust interception in automotive painting and baking paint rooms, as well as various industrial dust removal and air purification scenarios such as lithium battery positive and negative electrode material grinding, grain processing, wood processing, etc.

The three ear top polyester anti-static dust removal air filter element has a quick detachable structure that requires no tool operation and reduces downtime maintenance time by more than 90%; Polyester fiber with anti-static treatment, achieving both safety and efficiency; PTFE film is optional, with a filtration accuracy of up to 0.3 μ m and significantly improved dust holding capacity compared to ordinary filter materials; Standardized size compatible with multiple brands of dust removal equipment, no need to modify interfaces, and low cost of spare parts management.

① Decreased filtration efficiency: Due to dust accumulation, the pressure difference increases. When the inlet and outlet pressure difference reaches 250-350Pa, it should be replaced in a timely manner to avoid damage to the filter material caused by overpressure operation.

② Filter element damage: usually caused by improper installation or operation under excessive pressure difference. When replacing, ensure that the ear buckle is fully inserted into the slot and the end cover is tightly fitted to the interface.

③ Top seal leakage: Check if there are any foreign objects on the mating surface between the ear buckle and the slot, clean and tighten again, and replace the sealing gasket if necessary.

④ Blockage too fast: It is recommended to install a pre filtration device at the front end to intercept large particles of impurities, and choose the appropriate accuracy level according to the actual dust concentration to avoid overloading caused by a small aperture.
