Features:

1.BC three-lobe blowers needn't water coolant within 80kpa rising pressure.

2. The helical gears are adopted for much more stable conveying. 

3. By adoption of an special profile of rotor,the clearance between the rotors can be held to be constant,

which makes the efficiency even higher.

4. The precision of rotors is fully controlled by mass production on precise NC machines.In addition,

the rotors are almost free of vibrations since they are dynamically balanced in the fabrication stage 

already.

5. The helical timing gears are adopted not only to extend the use life but also to make noise lower.
