HR Series Roots Blower

Short Description:
"Shangu Brand" high-efficiency and high-volume Roots blower is an innovative product independently developed by Shandong Tomorrow Machinery Group Co., Ltd. Its features are as follows: 1.Reduce energy consumption. Models in this series are designed to deliver air pressure in the direction of impeller rotation, reducing the power required to drive the impeller. 2.Longer service life. Fewer impulses transmitted through the impeller means approximately20% longer load life. Other components such as timing gears, drive couplings, v-belts and motor bearings experience less stress due to less pulsation and vibration. 3.Less noise. Pressure pulses are often the main source of noise in blowers and gas blowers. The pressure balance effect of this model design reduces noise by about 5dBA.
