MJSR SERIES THREE LOBES ROOTS BLOWER
Shangu three lobes Roots Blower are new series Roots type blowers. With the help of CNC machine, we made precise rotors and casings to get a perfect gap to promote air performance, lower vibrations and noises results a significant improvement compared to traditional two lobe Roots Blower.Traditional Roots Blower lubricate bearings and gears with grease and oil.Shangu blowers with double oil tank need oil only.It is very convenient to maintain and oil has a better lubricating effect than grease. So it could be a longer bearings and gears life.
We currently produce 8 sizes of ROOTs blower units.

Frequently asked questions
For all sizes of unts, we produce our own acoustic covers, adapted to the location and customer requirements. These in conjunction with our silencers show a high noise attenuation efficiency.
At the same time, we design the set in the middle band of the speed spectrum so that the resulting sound pressure level is as low as possible.
If we know all the parameters, then processing and sending the offer is a matter of a few hours.
