Name: HFV-A Series High Vacuum Pump Oil Model: HFV-A Brief: wider temperature range compared to the M series
详细介绍
Performance
※ HFV-A series oil has wider temperature range compared to the M series.
※ 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 series oil keeps pump running at high vacuum degree,with a much longer service life.
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.
