[ Air Filter | Unit ]

Because the Air Filter is fiber with enormous vacancy, an air bone particles through one (1) yarn of the fiber inside the filter, would be usually caught by four effects such as;

1. Inertia Effect : A particle, approaching to fiber saddling with air flow, gets out of the flow by itself because of its inertia and is caught onto fiber of filter as striking. The effect comes to happen when both diameter of the particle and the filtering velocity are great.

2. Diffusion Effect : Tiny particle takes Brownian movement regardless the flow of air. Consequently, bigger particle, which might pass through the filter saddled with the flow, would be even caught onto fiber, since moving distance from filter is far and there is no orientation. The less filtering velocity of the particle is, the greater the effect will be.

3. Interception Effect : Even if a particle move saddled with the flow of air, it would be caught onto fiber as striking, since it has a certain size in itself.
The effect comes to happen when the rate of particle diameter vs. fiber diameter is great.

4. Gravitation Effect : A particle, approaching to fiber saddling with air flow, gets out of the flow by itself because of its gravitation, and caught onto fiber
The effect comes to happen when the diameter of particle is great but the filtering velocity of particle is little.
