HFV-WS Vacuum Pump for wide temperature

Properties of ultimate pressure, back stream rate , volume flow rate are similar to silicon oil and ester oil, not easy for resi
Performance
1. Reasonable composition, stable chemical character for special gas
2. 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 insulubility insulation film that will have effect on vacuum units.
3. Good oxidation stability,inhibition of oil dirt and coking,extending the oil-change intervals and saving costs.

Application
1. Applicable to variety domestic and foreign mechanical vacuum pumps.
2. Applicable to wide timperature range from -25to100.
3. Can be applied to special gases such as N
