Specifications

ZJ Series Vacuum Air Pumping Unit /Vacuum Drying Device Made in Chongqing

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.

This ZJ vacuum pumping unit is usually accepted by customers together with our ZJA vacuum oil purifier and GF dry air generator.

Custom options are always available!
