Model: HFV-WS32、WS46、WS68
Describe: The chemical composition is reasonable, the properties are stable, and it can be used in special gases.
Introduction: Applicable to all kinds of mechanical vacuum pumps at home and abroad.
Package: 1kg/can, 12 cans/box
The vacuum oil produced by Huifeng Enterprise is made of high-quality base oil and imported additives. It is an ideal lubricating material and is widely used in my country's military enterprises, display industry, lighting industry, solar energy industry, coating industry, refrigeration industry, aerospace, etc.
※ HFV-WS series high and low temperature vacuum pump oil has reasonable chemical composition and stable properties, and can be used in special gases.
※ It has similar characteristics to silicone oil and ester oil in terms of vacuum characteristics such as ultimate pressure, oil return rate, and pumping rate. The residual gas is not easy to form an insoluble insulating film to affect the vacuum components.
※ Good oxidation stability can reduce the generation of self-scaling and coking, reduce the number of vacuum pump replacements, and save production costs.
※ Reasonable chemical composition, stable properties, particularly for special gas.
※ Properties of ultimate pressure, back stream rate and pumping rate are similar to silicon oil and ester oil. It is hard for residual gas to produce insolubility insulation film that will have effect on vacuum units.
※ Good oxidation stability, inhibition of oil dirt and coking, extending the oil-change intervals and saving costs.
※ HFV-WS series high and low temperature vacuum pump oil is suitable for various mechanical vacuum pumps at home and abroad.
※ Suitable for occasions with a wide temperature range: -40 ℃ ~100 ℃.
※ This product can be used in special gases such as nitrogen, ammonia, hydrogen, helium, argon, carbon dioxide, sulfur dioxide, hydrogen sulfide, etc.
※ Applicable to various domestic and foreign mechanical vacuum pumps.
※ Applicable to wide temperature range from-40 ℃ to 100 ℃.
※ Can be applied to special gases such as N2, NH3, N3, Ne, Ar, CO2, SO2, H2S, etc.
