Vacuum Air Pumping Unit
1. Create Vacuum for Transformer
2. Vacuum Pump& Roots Pump
3. High Efficiency & Fast Speed

ZJ Series Vacuum Air Pumping Unit of waste oil/used oil recycling machine

 

It is mainly used for vacuum drying and vacuum oil-injecting for high voltage electrical transformer

 

as 220KV, 500KV,±800KV, 1000KV. Strong vacuum pumps make working vacuum degree to 10

 

Pa and limit vacuum degree to 1 Pa.

 

Features: 

GIS connection available

Digital vacuum degree management

Anti-absorption

Machine can start fast

Strong vacuum pumping capacity

Stable performance

Easy operation

There is a combination of axial fan and condenser to deal moisture and gas from vacuum pump and roots pump, it can prolong time to change vacuum oil while meet emission standard.
