Ultragrade Performance 70, 4l (H11028013) from Edwards
The Edwards Ultragrade 70, 4l (H11028013) mineral oil was specially developed for use in vacuum pumps, in particular for large pumps under demanding, frequently changing operating conditions. The unique hydrotreatment process, which removes nitrogen, sulphur, oxygen and aromatic hydrocarbons, produces a virtually pure base oil. In combination with additives, Ultragrade 70 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 70 is the best choice for demanding applications and guarantees optimum performance of your vacuum pump.
