Current location: Home > Industrial Lubricants > Vacuum oil and grease > HFV-AS High Vacuum Pump Oil > HFV-AS High Vacuum Oil
Model: HFV-A100S、A200S、A250S
Describe: The operating temperature range is wider than that of A high vacuum oil and the viscosity-temperature performance is better.
Introduction: It can be used for various mechanical vacuum pumps at home and abroad, such as Edwards from Britain, Leybold from Germany, Alcatel from France, Ulvoil from Japan, etc.
Package: 3.5kg/can, 4 cans/box, 13.5kg/barrel, 170kg/barrel
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-AS high temperature, high load high vacuum oil has a wider operating temperature range than A high vacuum oil and better viscosity-temperature performance.
※ Excellent oxidation stability and thermal stability, can maintain high vacuum operation for a long time under high temperature conditions.
※ Good foaming properties, reducing vacuum pump wear caused by overflow and interruption.
※ HFV-AS high temperature, high load high vacuum oil greatly extends the service life of the pump and reduces the number of oil changes.
※ HFV-AS oil has wider temperature range compared to the A.
※ Excellent oxidation stability and thermal stability to keep a high vacuum running for a long time at high temperature.
※ Desirable foam characteristics to reduce wear due to overflow and interruption of work fluid.
※ HFV-AS oil keeps pump running at high vacuum degree, with a much longer service life.
※ HFV-AS high temperature, high load and high vacuum oil is suitable for more demanding working conditions and can maintain a good vacuum state under high temperature, high pressure or high load conditions.
※ It can be used for various mechanical vacuum pumps at home and abroad, such as Edwards in the UK, Leybold in Germany, Alcatel in France, Ulvoil in Japan, etc.
※ 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.
