How To Calculate The Wind Speed Of Air Filter Cotton

There are many kinds of air Filter Cotton materials in the filtration industry, such as polyester fiber, glass fiber and activated carbon. Among them, polyester fiber is the most widely used material, and polyester fiber is suitable for use in various ventilation systems. Glass fiber is a high temperature resistant material and is suitable for high temperature environments. Activated Carbon Air Filter Media is suitable for removing odor and purifying the air.

Air filter cotton is divided into primary filter cotton and medium effect filter cotton. The wind speed of 15mm thick primary filter cotton is generally 3m / s, and the wind speed of 20mm thick primary filter cotton is generally 1.5m / s - 1m / s; 22mm thick The medium - efficiency filter cotton such as the ceiling filter cotton has a wind speed of 0.25m / s.
How to calculate the air filtration wind speed: V = L / A / 3600;

A: The unit of filter area is ㎡;
L: The unit of air volume is m³ / h;
V: wind speed in m / s;
3600 means 3600 seconds.

The effect of wind speed on Air Filter Material: In general, the slower the wind speed, the better the effect of air filter cotton. The diffusion effect of small particles of dust is very obvious. If the wind speed is low, the air can stay in the filter material for a longer time, and the dust in the air is more easily captured by the Air Filter Media. Most people think that the higher the wind speed, the higher the air filtration efficiency. In fact, this is wrong. On the contrary, the smaller the wind speed, the higher the air filtration efficiency.
