DN250 Three Lobe Roots Blower, 15-132KW, 80KPA air cooling rotary blower
BK blowers have improved full-adiabatic efficiency as well as volumetric efficiency and provide superior air
capacity vs.pressure characteristics.

Discharge differential pressure | 10-80KPA |
Rotary speed | 700-1500rpm |
Motor type | 15KW-132KW 380/400/415/440V, 3PHASES, 50/60HZ, frequency motor also available |
Motor brand | Standard: Siemens Beide or Wannan motor Siemens and ABB motor for your option |
Installation type | Standard: horizontal type. Vertical type available for your option |
| Color | Customized, standard of RAL6011 |
N.W. of blower without motor | 1310 kg |
Packing size Approx. | 2.62*1.78*2.45m (length*width*height) |
Features:
1.BK 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 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.
