Deep refinery, little aromatic and pectin
High flash point and high viscosity index,vacuum degree will not be reduced at high temperature
Good oil-water separability,will not emulsify while meeting water vapor
Oxidation stability, decrease stain and coke in oil, reduce frequency of changing oil
Application
Can be used to variety of mechanical vacuum pumps domestically and abroad
HFV-M100 is suitable for sliding vane rotary vacuum pump and roots pump with volume flow rate of 4 Liter, esp. for refrigerating industry with large pumping
HFV-M200 can be used for sliding vane rotary pump with volume flow rate from 5Liter to 30Liter ,esp. in color tube and illustration industry
Used in refrigeration, electro-vacuum, distillation, cryodesiccation,biology, chemical industry
