What are the air purification equipment?

①First-effect air filter
Description: The primary air filter is suitable for the primary filtration of air conditioning systems, mainly used to filter dust particles above 5μm. The primary filter has three styles: plate type, folding type and bag type. The outer frame materials include paper frame, aluminum profile frame, galvanized plate frame, and the filter material includes non-woven fabric, nylon mesh, activated carbon filter material, and metal mesh , Aluminum rolled mesh, etc.
Product features: low price, light weight, good versatility, compact structure
Main use: Commonly used as primary filtration of air conditioning and ventilation systems, and also suitable for simple air conditioning and ventilation systems that require only one level of filtration.
②Medium-efficiency air filter
Description: The medium-efficiency filter is widely used in the intermediate filtration of the air-conditioning system, and is suitable for occasions with high dust concentration. It adopts high-quality chemical fiber non-woven filter material and has a large dust holding capacity. Mainly used to filter 1-5μm dust particles, with the advantages of low resistance and large air volume. Medium-efficiency filters have bag type, frame type, combined type and other styles.
Features: large air volume, low resistance, stable performance, low price and strong versatility.
③Sub-high efficiency air filter
Features: It can be used as a pre-use filter for high efficiency filters to extend the service life of high efficiency filters.
Main application: Widely used in the air supply at the end of the air conditioner in the dust-free purification workshop of industries such as optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverage and food, PCB printing, etc. It can also be used for various vertical (horizontal) flow ultra-clean Workbench, laminar flow or turbulent flow industrial and biomedical clean room.
④High efficiency air filter
Main purpose: suitable for various local purification equipment and clean workshops.
⑤Air shower
The air shower is a necessary passage for people to enter the clean room, and it can reduce the pollution problems caused by people entering and leaving the clean room. The two doors of the air shower room are electronically interlocked, which can also function as an air lock room to prevent unpurified air from entering the clean room and reduce the pollution of the clean room by dust when people enter and exit the clean room. When a person enters the air shower room, the high-speed clean air flow is filtered by a high-efficiency filter and sprayed on the person from all directions by a rotatable nozzle, which can effectively remove dust particles carried by clothes, and the air with dust particles is filtered by the initial high efficiency After filtering, the filter recirculates to the air shower area.
