Self-cleaning Air Filter

The self-cleaning air filter is a new type of high-efficiency air filter with automatic cleaning function. It is especially suitable for long-term, continuous air purification of intake air under various conditions, effectively filtering fine pollutants discharged during production.

Working Principle

After air power equipment inhales dusty air, it will cause equipment wear, fouling on fan blades, reduced dynamic balance accuracy, shortened service life, and corrosion of equipment. Therefore, air power equipment must be equipped with high-precision air filters. The LFZK series self-cleaning air filters are improved based on similar air compressor intake air filters at home and abroad, and can fully meet the intake air requirements of industrial blast furnace blowers, air compressors and other equipment.

Filtration process: Dusty air is sucked into the primary coarse filter through the air compressor suction port, enters the high-efficiency filter cartridge, and dust adheres to the high-efficiency filter cartridge through gravity, inertia, diffusion, contact retention and other comprehensive effects. The clean air enters the air duct through the sealing ring, converges to the air collection port, and is sucked into the air compressor from the clean air outlet.

Self-cleaning process: After dusty air is filtered, dust is adsorbed on the high-efficiency filter cartridge. The pulse valve performs back blowing in a timed sequence. When the resistance value exceeds 600Pa, the PLC differential pressure sequence controls the back blowing process (back blowing time is 0.1-0.2 seconds). Other high-efficiency filters work normally, and dust is back blown and cleaned.

AdvantagesControlled by intelligent distributor, with three self-cleaning methods: timing, differential pressure and manual. It can realize automatic cleaning of air filter elements, ensuring normal operation of the equipment without affecting other filter elements. Reasonable design, no elbow pipe design, high-rise modular combination, convenient installation. Under general environmental conditions, the replacement cycle of filter elements can reach about 2 years.
