1. High-precision interception: It can accurately remove all kinds of impurities, such as capturing solid particles as small as 0.01 micron, like circuit board production in electronic manufacturing, to prevent fine dust from affecting the performance of electronic components. For liquid oil mist, the oil content in compressed air can be reduced to less than 0.01ppm, meeting the strict requirements of the food and beverage industry for oil-free air, and avoiding oil pollution products.
2. Multi-layer filtration: usually multi-layer filter element combination of different materials and filtration accuracy is used, the initial effect filter element first intercepts large particles, such as 5-10 microns of dust and rust; Medium effect filter element is responsible for filtering medium sized particles; The high efficiency filter element processes the tiny particles and ensures the high purity of the compressed air through this progressive layer.
3. High-quality materials: the shell is made of stainless steel, aluminum alloy and other high-strength metal materials. The stainless steel shell has strong corrosion resistance and is suitable for industrial environment with wet and chemical corrosion risk, such as chemical workshop; The aluminum casing combines high strength with low weight for easy installation and maintenance. The internal filter element is made of glass fiber, polyester fiber and other high-performance materials, glass fiber filter element has good high temperature resistance, corrosion resistance, can withstand high filtration pressure.
4. Structural design: With a strengthened structural design, can withstand high internal pressure, generally can withstand 10-15 bar or even higher compressed air pressure, to ensure stable operation in high pressure environment, reduce the risk of damage caused by pressure fluctuations.

1. Advanced sealing technology: The use of special sealing gaskets and sealants, such as silicone rubber, fluorine rubber gaskets, these materials have good aging resistance, high and low temperature resistance, can maintain the sealing effect in different working environments. The sealant is filled in the key parts of the shell and the filter element, the pipe connection, etc., to prevent gas leakage.
2. Strict testing: After strict sealing performance testing in the production process, such as using helium mass spectrometer leak detector for comprehensive testing of the filter, to ensure that there is no gas leakage even in the small gap, to ensure that the filtered clean air will not be polluted by the outside world.
3. Large size design: with a large filter area and flow aperture, the filter element size is large, increasing the contact area between the air and the filter element, reducing the air flow rate, so that impurities have more chances to be intercepted, while ensuring the smooth passage of air. The inlet and outlet pipe diameter of the filter is usually large to adapt to the large flow of compressed air in and out.
4. Optimize the internal flow path: The internal flow path is carefully designed and adopts a streamlined structure to reduce the flow resistance of air inside the filter and ensure that the pressure loss is small in the case of high flow rate. Generally, the pressure loss can be controlled within 0.5-1 bar to meet the demand for compressed air flow in industrial mass production

FAQ
1. Where is the best place to install the filter in the compressed air system?
It is usually installed downstream of the air compressor, after the gas storage tank. The compressed air discharged by the air compressor has a high temperature and contains a lot of impurities. After the initial cooling and precipitation of some liquid water and large particle impurities in the gas storage tank, the filter is installed at this time, which can effectively remove the remaining impurities and provide a clean air source for the downstream gas equipment. In addition, for gas equipment with high air quality requirements, such as precision instruments, medical equipment, etc., a filter with higher precision can be installed at the front end of the equipment for secondary filtration.
2. What are the requirements for pipe cleanliness when installing filters?
The pipe must be clean, free of rust, welding slag, dust and other impurities. If these impurities enter the filter, they may clog the filter element, shorten the service life of the filter element, and even damage the filter. Before installing the filter, the pipe should be purged and cleaned, and the pipe should be purged with oil-free, dry compressed air until there are no visible impurities in the blown gas. At the same time, check the inner wall of the pipeline to ensure that there is no obvious rust and debris attachment.
3. In addition to replacing the filter element, what maintenance work needs to be done on the filter?
Regularly check whether the shell of the filter is corroded, damaged, and whether the connection part is loose or leaking. Check whether the drainage device is working normally, and the manual drainage valve should be operated regularly to ensure smooth drainage and prevent water from being discharged when the automatic drainage device fails. In addition, the filter surface should be cleaned regularly to avoid dust accumulation affecting heat dissipation and the transparency of the observation window, so as to observe the internal conditions in time.
4. What factors affect the maintenance cycle of the filter?
It is mainly affected by the working environment, the pollution degree of compressed air, the frequency of use and other factors. In dusty, humid or chemically polluted environments, the maintenance cycle will be shortened; If the impurities in the compressed air are high, such as mining, casting and other industries, the filter element will clog faster and require more frequent maintenance; The high frequency of use and the long working time of the filter will also speed up the wear and blockage of the filter element, and the maintenance cycle should be shortened accordingly.
