Inertial dust collection

Suspended particles settle under the action of gravity   and their properties continue to move by inertia when the direction of the gas changes.
The most common designs that use this approach to air purification are louvered dust collectors and ventilation grilles. 

Gravity settling is used for coarse cleaning of medium particles (diameter 20-30 microns). Degree of purification - 65-85% (flow velocity - 1 m/s).

As a result, a large volume of solid multi-component (usually) waste is formed.

The disadvantage is also the rapid abrasion and clogging of cracks.
