Ultragrade 15, 1l from Edwards
The Edwards Ultragrade 15, 1l (H11026015) mineral oil was specially developed for use in vacuum pumps and is characterised by its unique hydrotreatment process, which removes nitrogen, sulphur, oxygen and aromatic hydrocarbons and thus yields a practically pure base oil. In combination with additives, Ultragrade 15 offers improved vacuum performance, thermal and oxidative stability and rust inhibition. The antioxidants contained in the oil allow the pump to withstand high operating temperatures without the oil degrading, which leads to longer oil change intervals. Ultragrade 15 is suitable for a wide range of applications and offers optimum performance for your vacuum pump.
