The Edwards Ultragrade 19, 1l (H11025015) mineral oil is specially designed for use in vacuum pumps and, thanks to its unique hydrotreatment process, offers an almost pure base oil. This process removes nitrogen, sulphur, oxygen and aromatic hydrocarbons and, in combination with additives, provides improved vacuum performance, thermal and oxidative stability and rust inhibition. The antioxidants in the oil allow the pump to withstand high operating temperatures without degrading the oil, allowing longer oil drain intervals. Ultragrade 19 is suitable for various applications and guarantees optimal performance of your vacuum pump.
