Bag Filter

The Dust extraction system proposed for this consists of Suction hood, Damper Valves, Ducting, Short Radius Bends, Bag Filter, pulsing arrangement and Centrifugal Fan.

The Suction hood is placed above / near the dusty area. The dusty air sucked during the operation by centrifugal fan, placed after the bag filter. Then the dust laden gases enter the bag filter & pass through the fabric bags that act as filters. The bags can be of woven, felted cotton, Nomex, glass fiber material etc. depending on the type of dust

Aircon spiracages will allow the bags to be correctively positioned, to receive the stream of air purged by pulse valve for the purpose of providing jerking movement to the bags, to avoid the deposit of dust particles on the bags which causes the choking of bag filter. The sequential timer placed near the bag filter will control the purging.
