Beijing Energy Saving and Environmental Protection Center Test Report

In February 2018, the Beijing Energy Conservation and Environmental Protection Center was commissioned by Shandong Dacheng Machinery Technology Co., Ltd. to conduct comparative tests on our company's Roots blower and multi-stage centrifugal blowers. Under the same working environment, we ensured that the blowers were in the same flow and In the same case of pressure, the single multi-stage centrifugal blower C120-1.6 is 20.16% more energy-efficient than the three Roots blower DSR200H, and the single multi-stage centrifugal blower is 17.79% more energy-efficient than the single Roots blower DSR300.
