The machine consists of an impeller enclosed in an impeller housing with a suction and exhaust port. As the impeller rotates at a high speed, a partial vacuum is created in the impeller housing and atmospheric air is sucked in from the suction port and exhausted from the exhaust port. This air suction is used for doing useful work. The machine is basically a vacuum cleaner, the suction side of which is used for cleaning purpose. It is connected to the tablet/polishing machine by a hosepipe from where the de-dusted powder is sucked out and collected.
