Dust laden air is drawn into dust collector through air inlet due to the suction created by the exhaust fan and passes through the fabric bags. Heavier dust particles fall into hopper due to loss of momentum. Finer dust gets deposited on the inner surface of the fabric bags and clean air passes across the outer surface of filter bags and exit into the atmosphere through the outlet. Bags are cleaned through motorised shaking arrangement.When motor is switched off, shaking cycle gets activated automatically and bags are shaken for preset time through the timer. Dust released from the filter bags slides downward into the hopper for further collection into the dust bin.
