These products perform more excellently than M series oil
Better anti-wear ability to reduce wearness of interface when compressing gas
Good oxidation stability, reduce the interfacial abrasion, delay the operation life of the pumps
Fine foam character to reduce wear due to overflow and interruption of work fluid
HFV-A series oil have longer operation life, keep pumps running at high vacuum degree
Application
HFV-A series oil are suitable for tough work condition and keep good vacuum degree under
condition of high temperature, high pressure or high load
Can be used in pumps of British Edwards,German Leybold, France Alcatel and Japan Ulvoil
