RENAIR Compressor Oils are blended from carefully selected solvent refined mineral oils, which provide optimum oxidation inhibition, excellent corrosion prevention and minimal coking tendency. RENAIR oils comply and exceed the requirements of DIN 51 506 for lubricating oils and DIN 51 356 for carbon residue. RENAIR oils contain additives to reduce wear and oxidation and therefore allow higher load, more severe operation conditions and prolonged oil service intervals.
