MTRR Double Stage ROOTs Blower

MTRR Double Stage Roots Blower is a high pressure roots blower designed by Shandong Mingtian Machinery Group.  A middle cooling system is installed between the first and the second stage blower, which will cool the temperature of airflow out from the first stage blower,and then the temperature of airflow into the second stage blower will be normal and will not damage the blower. By the two stage compression, Shangu MTRR two stage roots blower can reach the maximum pressure rise of 196KPA.

We currently produce 11 sizes of MTRR 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.
