Used Murphy Rodgers Model MRM10-2D Dust Collector. Unit includes silencer and motorized filter shaker. The material enters the unit in the primary separation section. All the heavy particles drop into the storage area. Then, only the finest particles rise into the secondary filter area. The dust is removed and the cleaned air passes up through the exhauster and out of the unit. When the filters are shaken the dust falls into the storage area, so there is only one dust pick-up point. Nothing goes through the exhauster but clean air. This not only protects and extends exhauster life, but also eliminates risk of fire caused by sparks generated when material hits exhauster blades. 230/460V 3 Phase 7-1/2 HP 1/6 HP motorized shaker 10” Inlet 2600 CFM at 6” W.G.
