Xinxiang Lifilter Self-cleaning Air Filter: An Outstanding Choice for Efficient Air Purification

In today's era with increasingly stringent requirements for air quality, high-efficiency and reliable air filtration equipment has become an essential choice for numerous industries. Xinxiang Lifilter Co., Ltd., relying on its profound technological accumulation and innovative spirit, has launched a self-cleaning air filter that has attracted significant attention in the market, providing high-quality air purification solutions for various places.

I. Analysis of Working Principle


The working process of Xinxiang Lifilter's self-cleaning air filter consists of two crucial steps: filtration and self-cleaning. These two steps complement each other to ensure the continuous and stable operation of the equipment.

(I) Filtration Process


Under the powerful suction negative pressure of the compressor, the surrounding ambient air is rapidly drawn into the filter. At this time, impurities such as dust in the air will undergo a variety of complex actions including gravitational settling, inertial diffusion, contact interception, and electrostatic adsorption. Under the combined influence of these physical effects, the dust gradually deposits on the outer surface of the filter cartridge filter media. The clean air that has passed through multiple layers of filtration then smoothly converges in the clean air chamber and finally enters the compressor through the outlet pipe, providing a clean air source for the equipment.

(II) Self-cleaning Process


The self-cleaning step is a major technological highlight of this filter. When the PLC issues a self-cleaning command, the solenoid valve will open instantaneously within an extremely short time (about 0.1 - 0.2 seconds), sending out a powerful pulsed air flow. This air flow passes through a carefully designed injection device and a Venturi tube, and conducts back-blowing on the outer surface of the filter cartridge at an extremely high speed and explosive force. Under the action of the back-blowing force, the accumulated dust on the outer surface of the filter cartridge is quickly blown off, thus restoring the good filtration performance of the filter cartridge. It is worth mentioning that the self-cleaning process has three intelligent modes, namely differential pressure, timed, and manual. In the differential pressure mode, as the dust continuously accumulates on the filter element, the pressure difference will gradually increase. When the pressure difference value reaches the preset pressure value, the system will automatically start self-cleaning. After the cleaning is completed, the pressure value decreases, and the self-cleaning process ends immediately; in the timed mode, the computer sets a timer, and after a specified period of time, it automatically controls and starts the self-cleaning system; the manual mode gives operators autonomous control rights, allowing them to manually operate the self-cleaning system according to actual needs. Regardless of which mode is adopted, the self-cleaning process will not affect the normal operation of other filter elements, ensuring the continuous and stable operation of the equipment.自洁式空气过滤器 03

II. Outstanding Features Demonstrating Advantages

(I) High-efficiency Filtration, Ensuring Air Quality


The Lifilter self-cleaning air filter is equipped with high-efficiency filter elements with extremely high filtration efficiency. Under general environmental conditions, it can effectively filter out tiny particles in the air and has excellent interception capabilities for impurities such as fine dust, providing high-purity air for gas-consuming equipment, greatly reducing the risk of equipment damage due to inhaled impurities, extending the service life of the equipment, and ensuring the stable operation of the production process.

(II) Powerful Self-cleaning Function, Easy Maintenance


The self-cleaning system of this filter is exquisitely designed and has a strong self-cleaning effect. Through the pulse back-blowing method, it can quickly and thoroughly remove the accumulated dust on the surface of the filter element, ensuring that the filter element is always in good working condition. Compared with traditional bag filters, its self-cleaning effect is more remarkable. Moreover, the self-cleaning process can achieve three control methods of differential pressure, timed, and manual through an intelligent distributor, with flexible and convenient operation. The degree of automation is high, and the main components are imported parts, enabling unmanned operation and greatly reducing the workload and cost of manual maintenance.

(III) Adaptability to Multiple Harsh Environments


It has excellent environmental adaptability and can work normally under the condition of a relative humidity as high as 99%, without fear of humid air in foggy and rainy seasons. At the same time, it can also operate stably in winter open-air low-temperature freezing weather and desert environments with a large amount of dust, demonstrating strong anti-humidity and anti-freezing capabilities. Whether in frigid regions or areas with severe sandstorms, it can provide reliable air filtration services for users.

(IV) Reasonable Structural Design, Superior Performance


It adopts an overall box-type structure with high structural strength and good sealing performance, effectively preventing air leakage and ensuring that the filtration effect is not affected. The equipment is lightweight, only 1/3 - 1/2 of that of the bag filter with the same capacity, facilitating installation and transportation. It has a large filtration area, low flow velocity, and small resistance loss, and there is a liquid crystal display for resistance loss, making it convenient for operators to monitor the equipment operation status in real-time. The service life of the filter element is long. Under general environmental conditions, the replacement cycle can reach about 2 years, reducing the cost and time loss caused by frequent replacement of filter cartridges.

(V) Personalized Customization Service


Fully considering the diverse needs of different users, non-standard designs can be carried out according to customer requirements. Whether it is adding a dust collection box or a dust-proof net at the bottom, or using a water flushing dust removal method to solve secondary pollution and other special requirements, a professional technical team can tailor suitable solutions for customers to meet their usage requirements under different working conditions.


Xinxiang Lifilter's self-cleaning air filter, with its advanced working principle and powerful performance characteristics, has demonstrated outstanding competitiveness in the air filtration field. It is widely used in various air separation devices such as blast furnace blowers in steel mills and air compressors, as well as high-power diesel engines, large air conditioners, and all large-air-volume equipment, solving air purification problems for numerous enterprises and facilitating efficient and stable production processes. It is an excellent choice among air filtration equipment.
