Let's learn about air purification knowledge

Air purifiers are used in home, medical and industrial fields. In the home field, single household air purifiers are the mainstream products in the market. The main function is to remove particles in the air, including allergens and indoor PM2.5. At the same time, it can also solve the air pollution problems of volatile organic compounds in indoor, underground space and vehicle caused by decoration or other reasons. Because the release of air pollutants in relatively closed space has the characteristics of persistence and uncertainty, using air purifier to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

The air purifier is mainly composed of motor, fan, air filter screen and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air will remove or adsorb various pollutants after passing through the air filter screen in the machine. Some models of air purifiers will also be equipped with negative ion generator at the air outlet (during operation, the high voltage in the negative ion generator generates DC negative high voltage), which continuously ionizes the air and generates a large number of negative ions, which are sent out by the micro fan to form a negative ion air flow, so as to achieve the purpose of cleaning and purifying the air.

Air filter are mainly apply for clean air-conditional system or delivery wind for purification equipment. According to the filter class level, it divided into primary filter(G1-G4), Fine Filter(M5~M6, F7~F9), HEPA filter(E10~E12, H13~H14), ULPA filter(U15~U17). According to the structure, there are Panel filter, Bag filter, V-bank filter(Box type), Separator filter, Compact HEPA filter, Gel sealed HEPA filter etc.

Primary filter could filtering 5um bigger particles, medium filter could filtering 1um bigger particles. They prevent the particles deposit at the surface measuring element surfaces such as temperature and humidity sensor, heat exchange element surface or air hose and improve the system controllability. At the same time they protect the endmost HEPA filter and extend the lifetime. HEPA filter mainly used at the endmost purification. The gas entering into the clean room or clean space directly after filtering to keep the environment reach the usage demand.

Bag Filter

We can see that bag structure to increase the filter area.German ultrasonic filter bag production line, a variety of welding procedures to meet the welding requirements of different filter materials. Filter bag linear welding, high strength, prevent leakage risk. High consistency of filter bag parameters toimprove product stability.

High Temperature-Resistant Separator HEPA Filter

From the introduction we can know that ambient air supply over 100℃ and 250℃, 280℃ are optional. Ultra-clean oven, tunnel sterilization and other purification equipment.High temperature filter paper, high temperature does not fall off the fiber, does not decompose. Aluminum foil spacing, silicone rubber seal, stainless steel frame, meet the temperature requirements.The reflexive border is equipped with stiffeners to meet the strength requirements.
