Product introduction：

LFZK series self-cleaning air filter Compressed air filter

LFZK series self-cleaning air filter has high precision, modular and modular structure. After the aerodynamic equipment inhales the gas containing dust, it will cause the wear of the equipment, the dust is adsorbed on the surface of the equipment, the harmful chemical components in the dust will make the equipment rust, corrosion, and reduce the service life of the equipment, so the aerodynamic equipment must be equipped with high-precision self-cleaning air filter.

2, can be repeatedly cleaned frame plate primary coarse filter, effectively prevent rain, snow, dust storms directly into the high efficiency filter cylinder, dust removal efficiency of 30%, weight ratio of 50%.

3, reasonable outlet pipe design, reduce filter resistance 20-30pa, withstand safety negative pressure -5kpa.

4, imported special pulse dust removal solenoid valve, life can reach ≥1 million times, electrical protection level 2P54.

5, modular building block structure, to meet customers for arbitrary processing capacity and special space shape requirements.

6, the use of JZJ series self-cleaning air filter is very simple, the user only needs to connect the air compressor inlet with the self-cleaning outlet.

Equipment composition:

LFZK series self-cleaning air filter is composed of filter barrel, solenoid valve, electric control box, coarse screen plate, Venturi tube, frame and so on.

Equipment name: 

Air filter, self-cleaning air filter, compressed air filter, high efficiency air filter, industrial air filter

Working principle：

The outlet of the clean air chamber of the LFZK series self-cleaning air filter is connected with the inlet of the air compressor, and the processing air is sucked from the atmosphere under the action of negative pressure. The air passes through the filter cartridge and the dust is blocked by the filter material. Numerous small particles of dust form a dust film on the windward surface of the filter material. The dust film can improve the filtration effect and increase the airflow resistance. When the resistance increases to the high limit of 600Pa, the pressure difference transmitter sends the resistance signal to the computer in the pulse controller, the computer issues the command, and the self-cleaning system starts to work; After receiving the instruction, the solenoid valve controls and drives the diaphragm valve according to the program. The diaphragm valve instantly releases compressed air, and its pressure is 600 ~ 800kPa. After rectification by the nozzle, the filter cylinder is backblown inside the filter cylinder, and the dust on the outer surface of the filter material is blown off, and the resistance decreases. When the resistance reaches the initial resistance of the filter material (about 150Pa), the self-cleaning system stops working.

FAQ：

Q: How efficient is this self-cleaning air filter?

A: It can filter particles up to 0.3-0.5 microns, so the filtration efficiency is higher. It mainly relies on HEPA filter element and pre-filter.

Q: How do I clean the filter?

A: It uses high pressure air through the nozzle to reverse wash the filter core, blowing away the dust that the particles stick to the filter surface, thereby reducing the resistance.

Q: What is the service life of the filter?

A: In particular, the service life of the pulse purge valve can reach 1 million times. The life of the filter element depends on the environmental pollution situation, generally at least 2 years.

Q: What kind of scenarios is it suitable for?

A: It is mainly applicable to the application scenarios that need to run for a long time and require high air quality, such as: air compressor station, air separation product oxygen station bellows, metallurgical heating furnace fans, etc.

Q: What kind of treatment gas?

A: It can handle 80~2400 cubic meters of gas per minute, suitable for small and medium flow treatment needs.

Q: What is the temperature range of the filter?

A: -45°C ~ +65°C, suitable for a wide temperature range.

Q: What about power consumption?

A: The power consumption range is <60 to 800W, depending on the processing flow. In general, the higher the processing flow, the higher the power consumption.
