The Filters for Cyclones
Sternvent after filters capture the fine dust that is not separated from the air stream of a cyclone dust collector. Simple and efficient, the after filters allow return of filtered air to the building or to comply with EPA requirement when exhausting the air outdoors.
Sternvent offers 3 sizes, 6 00-6,000 cfm, of after filters in two styles; 55 gallon drum & dust chamber. Available for indoor installation or outdoors, when ordered with weatherproof enclosure.
Filters are available 11-1/2” 05 5” diameter in polyester felt or cotton sateen. Ceiling hung and floor-mounted units are available.
Principle of Operation
The dirty air stream enters the plenum horizontally; the filters hang from the plenum. The air and dust go down, inside of the filter bags. The dust is stored in the 11-1/2 diameter filters. The 5” diameter filters are tubes that allow the dust to be deposited in the airtight 55 gallon drum or chamber.
Some models are available with a motorized shaker to loosen the dust particles from the filters, to restore suction. Filtration efficiency is typically 99.9%. (For production operations, additional filter media is suggested. For sticky or agglomerating dust, a pulse jet style dusty collector should be used instead of the after filter.)
