Product Advantage
1,Optimized lobe curve is adopted for reducing blower’s internal leakage,improving blower’s 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 smooth operation.
4,Deep groove ball bearing of high precision and low friction factor is selected for lowering operation noise.In addition,because of large 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 consumption.
