The automatic back-blowing system adopts the pulse high-pressure air flow back-blowing technology. Through the programmable logic controller (PLC), the opening and closing of the back-blowing solenoid valve are precisely controlled, causing the high-pressure air flow to be sprayed onto the surface of the filter material in a pulse form, generating intense vibration and air flow impact, which thoroughly removes the dust and impurities adhering to the surface of the filter material. The back-blowing process can automatically adjust the back-blowing frequency and duration according to the changes in dust concentration and pressure difference, avoiding energy waste caused by ineffective back-blowing. Through actual measurement, it has been found that this automatic reverse blowing system can extend the service life of the filter material by 2 to 3 times, significantly reduce the frequency of filter material replacement, and at the same time, minimize the downtime of the blower caused by manual maintenance, thereby enhancing the operational efficiency of the equipment.
In terms of durability design, the product fully takes into account the complexity of industrial environments. The filter material frame is made of high-strength aluminum alloy, which is lightweight and corrosion-resistant, and can adapt to industrial environments with high humidity and many corrosive gases. The filter material itself has undergone oil-proof and water-proof treatment, ensuring stable filtration performance even in an intake environment containing oil stains or water vapor, thus preventing clogging or damage due to moisture absorption. The shell is made of cold-rolled steel plate, which is treated with acid washing and phosphating and then coated with epoxy resin. It has strong impact resistance and excellent corrosion resistance, effectively resisting collisions and chemical corrosion in industrial sites. Its service life can reach more than 5 years.

The application fields mainly focus on large industrial blower systems. In the power industry, it is suitable for the induced draft fans and forced draft fans of boilers in thermal power plants, as well as the cooling air filtration of gearboxes in wind power generation equipment. In the chemical industry, it is used for the air intake filtration of aeration fans and material conveying fans in chemical reaction vessels. In the metallurgical industry, it is suitable for converter fans and blast furnace blowers in steel mills, as well as ventilation equipment filtration in the non-ferrous metal smelting process. In the sewage treatment industry, it is used for the purification of the intake air of the blower in the aeration tank to prevent dust and impurities from entering the aeration system and causing blockage. In addition, this product can also be applied to large-scale fan equipment in industries such as cement production, papermaking, and textile printing and dyeing, providing customized filtration solutions for various industrial fans.
