Dust Doctor: Industrial ventilation – Another look at controlling airborne dust
Columnist John A. Constance discusses industrial ventilation methods, including dilution and displacement ventilation and local exhaust ventilation.
One of the more common purposes of industrial ventilation is to minimize employee exposure to nuisance and hazardous dust or fume particulates. The two most common industrial ventilation methods to control process-generated dust are dilution ventilation (or a variation, displacement ventilation) and local exhaust ventilation (that is, dust collection). These may be applied within the entire plant building or an enclosed workspace within the plant.
