Principle of Operation :

The dust generated is picked by a slitted hood in an air steam generated by powerful suction blower. Dust separation takes place in two stages. In the primary stage, heavier particles are deposited into the collection container due to reduction in velocity and change of direction of air. Secondary separation occurs when the lighter dust is deposited onto the fabric by initial impact and diffusion. Hence, its accumulates to form a mat or bed, which in turn acts as filter medium with a fabrics periodically removed from the fabric by the shaker mechanism and deposited into the collection container
