Air filter air filter is generally used to clean shop, clean rooms, laboratories and clean operating room air conditioning system. According to their works can be divided into the primary filter, medium filter, sub-high efficiency filter and high efficiency filter. 
 (1) the initial efficiency air filters: resistance is small, large air volume, the use of a wide range, long life, and its main features. Range: for the primary filter of the air-conditioning systems, mainly used to filter dust particles above 5μm. 
 (2) efficiency air filter: it can be used for primary filtration of the air conditioning system, to a filter protection system and the system itself, in place of air purification cleanliness requirements, in effect filter processing The air can be directly sent to the user. Border aluminum, galvanized sheet material, filter material for non-woven fabrics, activated carbon, filter diameter of 1 ~ 5um filter efficiency of 60 to 95 percent. 
 (3) high efficiency air filters for the use of micro-electronics industry, precision instruments, defense, aerospace, instrumentation, medical and health, bio-engineering, laboratory, pharmaceutical and food industries and all kinds of clean room, clean the tunnel, and efficient outlet, clean bench, air shower room, and other purification equipment, air terminal filter. The product uses ultra-fine glass fiber filter, hot sol dividers, special aluminum frame, polyurethane two-component sealant, closed-cell sponge seal, spray the steel net uniform flow plate undergo a rigorous refining process. 
 All products can be customized according to customer.
