Edwards Ultragrade Performance 20, 1l (H11024015).

Edwards Ultragrade 20, 1l (H11024015) is a specially developed mineral oil for vacuum pumps, which offers an almost pure base oil thanks to its unique hydrotreatment process. 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 degrading the oil, resulting in longer drain intervals. Ultragrade 20 is versatile and will ensure optimal performance from your Edwards vacuum pump.
