Our roots blower
Working Principle: ZhanEr roots blower (dry type roots vacuum pump), are positive displacement machines consisting of a pair of three-lobe rotors machined with high precision, rotating inside an oval shaped casing at the same speed, but in opposite direction. One rotor is driven by external power while the other rotor is driven by synchronous gears. As the rotors rotate, air is drawn into inlet side and forced out the outlet side to achieve functions of air blowing and extracting. Properties: ZhanEr roots blower (dry type roots vacuum pump) provides substantially constant output rate, i.e. volume of airflow at inlet varies little when pressure increased or vacuum status changed, conveys oil-free air or gas, properties of which normal three-lobe blower possesses as well. However our roots blower owns unique advantage of adopting the most advanced structure of special shaped inlet/outlet port and internal leakback variation, which effectively attenuates leakback-induced noise, resulted in much lower pulsation and noise level.
