Edwards Ultragrade 15, 4L
Edwards Ultragrade 15, 4l (H11026013) mineral oil has been specially developed for use in vacuum pumps and features a unique hydrotreatment process which removes nitrogen, sulphur, oxygen and aromatic hydrocarbons to provide a virtually pure base oil. In combination with additives, Ultragrade 15 offers 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, resulting in longer drain intervals. Ultragrade 15 is suitable for a wide range of applications and offers optimal performance for your vacuum pump.
