Product Details

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.

Performance

※ HFV-A high vacuum oil has a wider operating temperature range than M high vacuum oil.

※ The product's anti-wear performance is significantly improved, which can reduce the interface wear during pump compression.

※ Good foaming properties can reduce the wear of vacuum pumps caused by overflow and interruption.

※ HFV-A high vacuum pump oil greatly extends the service life of the pump and allows the vacuum pump to maintain high vacuum operation for a long time.

※ HFV-A high vacuum oil has wider temperature range compared to the M.

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

※ Superior oxidation stability to effectively extend the oil-change intervals.

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

※ HFV-A high vacuum oil keeps pump running at high vacuum degree,with a much longer service life

Application

※ HFV-A high vacuum oil is suitable for harsh working conditions and can maintain good vacuum degree under high temperature, high pressure or high load conditions.

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

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

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