Zjb series single-stage high-efficiency vacuum filter is mainly used to purify transformer oil, turbine oil, N68 oil, hydraulic oil, can also be used for vacuum transformer oil. The utility model has the advantages of small volume, light weight, high purification efficiency, low working noise, convenient maintenance, etc. . It can effectively remove water, impurities and gases such as methane and ethane in oil, and improve the flash point and pressure resistance value, the parallel connection with the regeneration device can accelerate the acid removal, decolorization, reduce the dielectric loss and acid value, and improve the insulation strength. For Oil with breakdown voltage not less than 15KV, the withstand voltage of ZJB single-stage vacuum filter can reach above 60KV. Sentence is too long, please supply a shorter sentence
