MTRR Double Stage High Pressure Roots Blower

Shangu MTRR series is a two-stage roots blower.  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 of 196KPA.

The blower is of positive displacement type roots blower, and sends a fixed amount of air in proportion to its rotation speed.With the three-lobed rotors, the two rotors make three intake and exhaust cycles per revolution. Because the air has less pulse compared with the two-lobed type, fluctuations in load, noise and vibration are small. While the two three-lobed rotors mounted on two parallel shafts maintain only a very small clearance between themselves and the inner surfaces of the oval casing operation chamber and between each other, they are driven by timing gears, moving a fixed volume of the air enclosed by the casing and rotors from the intake side to the output side. The roots blower is free of Internal lubrication. And its simple design, easy handling, and stable performance make a wide range of applications possible.
