A centrifugal air filter works by using rotational motion to separate particles from an air stream based on their mass. The key principle is utilizing centrifugal force.
Here's a breakdown of the process:
-
Air Intake and Rotation: The air enters the centrifugal filter, typically in the axial direction (along the axis of rotation). A motor or compressed air drives the filter's rotation.
-
Centrifugal Force Application: As the filter rotates, the air within it also rotates. This rotation causes centrifugal force to act upon all the particles within the air stream. Centrifugal force is the apparent outward force experienced by an object moving in a circular path. Heavier particles experience a greater centrifugal force than lighter particles.
-
Particle Separation: Due to the differing centrifugal forces, heavier particles are forced outwards, towards the outer walls of the filter or a collection chamber. Lighter, cleaner air remains closer to the center of the filter.
-
Collection: The separated particles collect on the outer walls or within a designated collection area. This collection area is designed for easy removal of the accumulated particulate matter.
-
Clean Air Exhaust: The cleaner air, now mostly free of larger particles, is exhausted from the center of the filter.
In summary, a centrifugal air filter spins the air stream, using centrifugal force to fling heavier particles outwards for collection, allowing cleaner air to exit.
