Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air quality. Dust collector systems work in general by drawing dust and particulates from the air through a filter that first captures and separates the matter, and then discharges purified air back into the workplace or environment.
