Three lobe double oil tank Roots Blower

1）The Roots blower is a volumetric fan.

2）The air flow is proportional to the speed. The three-lobe impeller rotates each time, and two impellers breathe and exhaust for three times

Compared with the two-lobe type, the gas pulsation is less, the load changes is smaller, the mechanical strength is stronger, the noise is low, and the vibration is small

3) There are 2pcs three-lobe impellers on the two parallel shafts. The slight gap is between the impellers and the inner surface of the elliptical tank and each impeller.

The impeller rotates at a constant speed in the opposite direction. A certain amount of gas surrounded by the tank and the impellers is transported from suction side to exhaust side

4) Each impeller and synchronizing gear always keep the correct phase position, mutual contact does not be happened , so it can be speeded up without internal lubrication, it is simple , stable operation and performance, it adapts to various purposes and uses in a wide range of fields.
