The unique compressed air filter is mainly used to filter dust, metal wear dirt, condensate, lubricant, acid condensate, oil mist, hydrocarbon and other impurities in the compressed air system. The filter shell is made of high-quality aluminum alloy and carbon steel, processed by advanced technology, and coated with epoxy resin powder. The internal filter element adopts imported high-efficiency separation filter material and special agglomerating material with complete manufacturing specifications and Accuracy grades to replace the imported filter element equivalently. In addition, it can be equipped with differential pressure gauge, liquid level gauge, automatic drainer and other accessories. After years of practice and application, this product can completely replace imported products, and meet the requirements of compressed air purification treatment in various occasions at home and abroad. Product characteristics 1. Expand the flow path to reduce the pressure drop 2. The shell is made of high-quality aluminum alloy and carbon steel or stainless steel 3. Spray epoxy powder on the surface to improve durability and corrosion resistance 4. The inlet and outlet adopt the threaded interface type, and the air flow direction is marked on the shell, which is easy to install 5. Compact design, reducing the space required for maintenance 6. Accurate time for changing filter element indicated by accurate differential pressure gauge 7. The liquid level indicator can easily monitor the liquid level, and pay attention to the situation requiring preventive maintenance at any time to avoid downstream pollution 8. Reliable automatic drainage device Working pressure correction factor When the pressure is not 7kgf / cm2, the flow of the selected filter shall first know the maximum flow at the filter inlet, and then divide by the correction coefficient corresponding to the minimum pressure at the filter inlet to select the appropriate filter specification. For example, the minimum air inlet pressure of the optional filter is 10kgf / cm2, the nominal flow is 10nm3 / min, and the corresponding correction coefficient is 1.37, so the maximum flow of the optional filter should be 10 / 1.37, namely 73nm3 / mi
