Engart Dust Extractor Operation

Engart Dust Extractor Operation

Engart extractors include a motor, radial impellor fan, bifurcated transfer housing, knitmesh screen extraction panel, louver demister panel and control regulators. The fan creates static pressure which draws air into the inlet end of the extractor.
Dust laden air is captured with hoods and transported through ductwork to the extractor. Unducted operation is also possible in applications such as auxiliary ventilation in underground mining.

Water is injected at the inlet of the fan impellor where it is spun with the incoming air and dust to impact with high energy against the fan housing. Water, dust and air pass through the bifurcated transfer housing to the extraction panel which removes water and captured dust to a discharge sump at the bottom. The louvered demister panel captures any overspray from the extraction panel. Cleaned air exits the exhaust end of the extractor. Engart extractors operate with 99.7% removal efficiency based on independent testing on PRB coal dust.
