Atlas Copco air filters

This air filter 2914930100 mainly filters out particles through the diffusion effect. It is widely loved by users because it can filter out fine particles. For small particles, because their diameter is smaller than the pore size of the fiber, they cannot be directly intercepted or inertially deposited. However, air filters use the diffusion effect, that is, when particles collide with gas molecules, they tend to follow the oscillating motion of the gas, and eventually collide with the fiber and be captured.
