In the Rotary Cyclone the amount of air handled by a single cyclone is divided among number of small cyclones place in the series. By doing so we can reduce height required for the cyclone. Air enters tangentially in the single cyclone while Mitsuba Rotary cyclone has axial entry with Rotary Vanes at the entry of each cyclone which provides extra spin to create the high centrifugal force, which in turn increases the collection efficiency of rotary cyclone.
