ZLJ30-50 type vacuum oil filterDetailed product description：

Product Introduction:
ZLJ30-50 vacuum oil filter (high-efficiency vacuum oil filter)

Purpose: It can efficiently purify water, gas, and impurity particles in transformer oil, transformer oil, switch oil, refrigeration oil, and other oils, and perform vacuum drying, vacuum oil injection, and vacuum pumping on high-voltage power equipment. And it can purify and regenerate degraded transformer oil, transformer oil, switch oil, etc. without power outage, so that they can reach the new oil index and restore their performance.

Characteristics of ZLJ30-50 vacuum oil filter:
The structure is novel and reasonable, with the heater set inside the vacuum cylinder, good insulation performance, and an efficient atomization device to quickly evaporate gas and water in the oil. There is an automatic oil level controller inside, and the high-pressure thruster does not need to destroy the vacuum under any circumstances. The filtering effect is good, and all technical indicators meet the national DL/T521-93 standard.
