Characteristics of plate type medium effect air filter
It can collect dust and all kinds of suspended particles of 1-5um. It uses heat and melt technology to stabilize structure, reduce the risk of breaking and leakage, large air volume, small resistance, high dust volume, and can be used repeatedly and clean. Type: frame free and frame bag type, filter material: special non-woven fabric or glass fiber, efficiency: 60% ~ 95%@1 ~ 5um (colorimetric method), use the highest temperature, humidity: 80, 80%.
Filter principle of plate type medium effect air filter
1. intercepting: the dust particles in the air, moving with the air flow as an inertial motion or irregular Brown movement or by the action of some field force. When the particle motion hits other objects, the Fan Dehua force (the force between the molecules and molecules, the molecular mass and the molecular mass) exists between the objects to make the particles stick to the surface of the fiber. The dust entering the filter medium has more chances to hit the medium, and the impact will be sticky. Smaller particles collide with each other to form larger particles and settle. The concentration of particles in the air is relatively stable. The decoloration of the interior and walls is because of this. It is wrong to regard fiber filters as sifting.
2. inertia and diffusion: particle dust in the flow of inertia in the air, when encountered in the arrangement of disorderly fiber, the direction of the air flow changes, particles because of inertia deviation, bump into the fiber and be bonded. The larger the particle, the more easily the impact, the better the effect. Small particle dust is used as an irregular Brown movement. The smaller the particles, the more irregular movement is, and the more chance of impacting obstacles, the better the filtering effect. The particles in the air less than 0.1 microns are mainly used for Brown motion, with small particles and good filtration effect. Particles larger than 0.3 microns are mainly inertial. The larger the particle is, the more efficient it is. Diffusion and inertia are not obvious. Particles are the most difficult to filter out. When measuring the performance of high efficiency filters, people often stipulate the dust efficiency value which is the most difficult to measure.

4. chemical filtration: chemical filters are mainly selective adsorption of harmful gas molecules. There are a large number of invisible pores in activated carbon materials with large adsorption area. In the active carbon of rice grain size, the area inside the micropore is larger than a dozen square meters. After the free molecules contact the activated carbon, the liquid condenses in the micropore and stays in the micropore because of the capillary principle, some of them are integrated with the material.
