Classification And Characteristics Of Air Filters

Air filters are generally used for dust prevention in clean workshops, clean factories, laboratories, clean rooms, as well as electronic, mechanical, and communication equipment. They refer to air filtration devices. Mainly used for air intake purification and removal of dust particles. The exhaust gas used in industrial production processes also contains small pollutants, such as radioactive substances, oil mist, etc. Usually, this type of purification belongs to exhaust purification, and the purification requirements are relatively high, and air filters are also required.
Air filters are divided into primary efficiency filters, medium efficiency filters, and high-efficiency filters. Different models of air filters have different standards and usage efficiency. If the primary air filter is used, it is generally used in the filtration section of ventilation air treatment equipment or the primary filter of fresh air systems. The characteristics are compact overall structure, light weight, and easy disassembly and installation. Moreover, after using the primary filter for a period of time, it can also be blown and reused with an air gun, greatly saving operating costs.
Medium efficiency air filters, due to their higher dust capacity and longer service life, are generally used in conjunction with primary efficiency plate filters in the automotive industry, hotels and office buildings, central air conditioning and centralized ventilation systems, clean rooms, and return air conditioning systems.
The specific characteristics of high-efficiency air filters are low resistance, large air volume, and high efficiency. They can be used continuously for a long time and can reduce the cost of consumables in the later stage. Mainly used in the end air supply outlet of clean rooms, FFU, clean equipment, etc.
