This type of dust collector consists of number of tubular fabric type filter bags to trap the impurities contained in the incoming air. Incoming air moves into the inlet of the dust collector by suction draft produced by the Exhaust Blower and passes through the number of tubular filters which retain the fine dust particles on its outer periphery and only allow the clean air to pass through the outlet side.
For cleaning of these filter bags, after regular intervals, exhaust blower of the dust collector is stop and filter tubes are shaken mechanically to remove the dust accommodated on the outer surface of the filter tubes. These dust particles falls down into the bottom hopper of the dust collector. These dust get collected into the trays placed at the bottom and are taken out periodically and emptied.
