During the operation of the air compressor filter, some external factors will affect its use, and wind speed is one of them. In most cases, the lower the wind speed, the better the filter will work. The following China Air Compressor Xiaobian will come to you to explain specifically.
For large particle dusts based on the inertial mechanism, according to the traditional theory, after the wind speed is reduced, the probability of dust colliding with the fibers is reduced, and the filtration efficiency is reduced. However, in practice this effect is not obvious, because the wind speed is small, the rebound power of the fiber against the dust is also small, and the dust is more likely to be stuck.
If the service life of the China Air Compressor filter is based on the final resistance and the wind speed is high, the filter has a short service life. It is difficult for the average user to actually observe the effect of wind speed on the filtration efficiency, but it is much easier to observe the effect of wind speed on the resistance, so if the wind speed is large, the resistance will also become larger.
The diffusion of small particle size dust is obvious, the wind speed is low, the airflow stays in the filter material for a longer period of time, and the dust has more chance to hit the obstacle, so the filtration efficiency is high. Experience has shown that for high-efficiency filters, the wind speed is reduced by half, the dust transmission rate is reduced by nearly an order of magnitude, the wind speed is doubled, and the transmission rate is increased by an order of magnitude.
Similar to the effect of diffusion, when the filter material is electrostatically charged, the longer the dust stays in the filter material, the more likely it is to be adsorbed by the material. Changing the wind speed, the filtration efficiency of the electrostatic material will change significantly. If you know that there is static on the material, you should minimize the amount of air passing through each filter when designing your air conditioning system.
For high-efficiency filters, the velocity of the airflow through the filter material is generally 0.01 to 0.04 m/s. Within this range, the resistance of the filter is proportional to the amount of filtered air. Therefore, screw air compressor company suggested to Xiaobian that when you use it, try to be in a room with a small wind speed.
