Type features:

1. Two- pole motor with TEFC IP55 and insulation F, high temperature resistant to180°

2. Motor reached Europe EFF2 standard, save more electricity, and more durable.

3. In front bearing structure makes dynamic stability;

4. The rotating parts are not in contact with the casing. No friction during operation, No internal lubrication needed.

5. Sealing ring is placed between housing & motor to prevent entry of foreign matter, improve service life;

6. Wide range of powers and sizes, long term and quietly smooth operation.


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.
