Name: HFV-B High Vacuum Pump Oil Model: HFV-B Brief: Excellent high temperature oxidation stability, greatly extend the life of the oil.

详细介绍

Performance

※ HFV B series oil developed according to special conditions required of customers on the basis of the HFV-A Series  

※ Excellent anti-wear ability to reduce interface wear when compressing.

※ Excellent high temperature oxidation stability, greatly extend the life of the oil.

※ Desirable foam characteristics to reduce wear due to overflow and interruption of work fluid.

 

Application         

※ Applicable to poor working conditions and keeping good vacuum degree under conditions of high, pressure or high load.

※ Can be applied to various domestic and foreign vacuum pumps such as the British Edwards,German Leybold,French Alcatel and Japanese Ulvoil.
