Working principle of vortex blower

Impeller rotation due to centrifugal force,the impeller due to the rotation of the gas flow along the blade and the radial direction of acceleration,the gas into the outer air ring,the use of differential pressure back to the base of the blade,The formation of

strong air,soagain and again so that the gas in the gas ring in the spiral direction ofmovement to produce a certain pressure. After  the  gas   moves  to  the  exhaust   port,the  gas   is  exhausted   because  the   pressure  is  greater  than  the  external   pressure

Squeeze   and   drain   quickly.
