1,Using advanced spiral back into the exhaust port and within the technique, the body effectively delayed the return of high-pressure gas shocks, so fans, the noise is significantly reduced;
2, Rotor use of advanced composite curve, teeth together more reasonable and improve the fan Efficiency;
3,seal structure is reasonable, oil and gas can not enter the device and therefore, the output air is clean, free of oils and fats;
4,with high precision, hardened gears, enabling the machine to further im...
