BHB series operating principle

   The gas is taken in through the inlet 1, as it enters the side channel 2, the rotating impeller 3 imparts velocity to the gas in the direction of rotation. Centrifugal force in the impeller blades accelerates the gas outward and the pressure increase.Everyrotation adds kinetic energy, resulting in the further increase.Everyrotation adds kinetic energy, resulting in the further increase of the pressure along the side channel. The side channel narrow at the rotor, sweeping the gas off the impeller blades and discharging it through the outlet silencer 4 where it exits where it exits the side channel blower.
