Name: HFV-WS Screw High and Low Temperature Vacuum Pump Oil Model: HFV-WS Brief: Good oxidation stability,inhibition of oil dirt and coking,extending the oil-change intervals and saving costs.

详细介绍

Performance

※ 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.

Application         

※ Applicable to various domestic and foreign mechanical vacuum pumps.

※ Applicable to wide temperature range from-25 oC to 100 oC.

※ Can be applied to special gases such as N2, NH3, N3, Ne,Ar, CO2, SO2, H2S,etc.
