LAFARGE cement uses 8 sets of air bearing blower and magnetic turbo blower for energy saving renovation

The goal of this technical renovation is: 3 units RAETTS blowers in the first line and 5 units RAETTS air blowers in the second line to achieve the purpose of energy saving and noise reduction. The new blowers will be put into operation in January 2022.

Comparing with original roots blower,after renovation,RAETTS air blower is expected to save about 1,472,904 kWh of electricity per year, and save about 662,806.8RMB in electricity expenses.
