BK Type Three Lobes Roots Blower 3 Lobe Blower Low Noise
Product Description:
1. Optimized lobe curve is adopted fcr reducing blowers internal leakage, improving blowers efficiency and reducing running temperature.
2. After shaft's diameter enlarged, no deformation and collision will occur under higher load pressure as the blower's strength is improved.
3. The synchromesh gear adopts straight tooth structure for samooth operation.
4. Deep groove ball bearing of high precision and low friction factor is selected for lowering operation noise. In addition, because of larger size bearing matched for enlarged shaft diameter, the bearing's load capacity is enhanced and its service life is extended.
5. Low noise and vibration, compact and economical energy con sumption.
