Model ZLH Transformer Vacuum pump Set
Introduction:
The transformer drying vacuum pump Model ZLH is specially for vacuum drying and vacuum oil injecting for high voltage electrical transformer from 220kV-1000kV. And it equips both rotary vane vacuum pump and Boosting roots pump, the working vacuum degree is 50Pa or better.
There is a combination of condenser to deal with moisture and gas from the vacuum pump and roots pump, which can prolong time to change vacuum oil while meeting emission standards. It's two sage vacuum pumps with good vacuuming degree.
Features:
Automatic control with easy operating
Flange connection available
Pirani vacuum gauge
The booster Roots pump can Start quickly
Strong vacuum pumping capacity
