Ultragrade Performance 20, 4l (H11024013) from Edwards
Edwards Ultragrade 20, 4l (H11024013) is a specially developed mineral oil for vacuum pumps which, thanks to its unique hydrotreatment process, offers a virtually pure base oil. This process removes nitrogen, sulphur, oxygen and aromatic hydrocarbons and, in combination with additives, results in improved vacuum performance, thermal and oxidative stability and rust inhibition. Thanks to the antioxidants it contains, the pump can withstand high operating temperatures without the oil degrading, which leads to longer oil change intervals. Ultragrade 20 is versatile and ensures optimum performance of your Edwards vacuum pump.
