Klüber Summit SB 46


Klüber Summit SB 46 Is a synthetic air compressor oil for oil change intervals up to 8,000 operating hours


Benefits for your application


– Low maintenance and operating costs due to extended oil change intervals up to 8,000 operating hours in oilinjected screw-type compressors
– Easy compressor oil conversion due to neutral behaviour of oils towards seals
– Low tendency to evaporation ensures clean (oil-free) compressed air and oil-free compressed air ductwork system,
no unnecessary cleaning or failure of gummed pneumatic valves
– Low formation of oxidation residues in the oil circuit, reduced operating costs due to extended oil filter and separator life




Klüber Summit SB oils are air compressor oils based on synthetic hydrocarbons and additives. These oils are miscible with mineral oils and synthetic hydrocarbon oils, but not with oils based on polyglycol.

Klüber Summit SB oils offer excellent oxidation and ageing stability and show a good viscosity-temperature behaviour.



Klüber Summit SB oils have been especially designed for screw-type compressors subject to high loads. They are used for oil change intervals up to 8,000 operating hours in air compressors.

Klüber Summit SB oils can be used for compressors that were previously run with mineral oils. Klüber Summit SB oils are neutral towards most elastomer seals used in air compressors, therefore leakage is not to be expected.

Klüber Summit SB oils offer good oxidation stability due to the synthetic base oil content, thus minimising oxidation residues in the compressors and extending oil change intervals and the service life of oil filters and separators. Special inhibitors contained in the oil keep the inside of compressors clean and ensure a high efficiency.

Owing to the evaporation stability of the base oil, the oil vapour content in the compressed air can be reduced several-fold compared to conventional mineral oils. This contributes to a reduction of oil consumption and clean compressed air; it also helps to prevent gumming of pneumatic valves in the compressed air circuit.

Application notes


When selecting the oil viscosity for air compressors please observe the manufacturers’ instructions.

When switching a used compressor to Klüber Summit SB oils, drain the old oil from the whole circuit while still warm. We also
recommend changing all oil filters and separators. Then refill the compressor with Klüber Summit SB oil.

When switching from mineral oil to a Klüber Summit SB oil please consider that the compressor may contain oxidation residues in the form of blackened or contaminated oil. As such residues can affect the service life of the fresh Klüber Summit SB oil, the compressor should be cleaned using the Klüber Summit Varnasolv conditioner.

For further information, please consult the Klüber Summit Varnasolv product information leaflet or contact Klüber Lubrication.
After switching to a Klüber Summit SB oil we recommend determining the oil change interval through an oil analysis or the Klüber Summit TAN Kit.
