Klüber Summit SH 68


Klüber Summit SH 68 Is a synthetic air compressor oil for oil change intervals up to 10,000 operating hours.


Benefits for your application


– Low maintenance and operating costs due to extended oil change intervals up to 10,000 operating hours in oilinjected screw-type compressors
– Easy compressor oil conversion due to neutral behaviour of oils towards seals
– Low tendency to evaporation and thus low impact of the oil vapour on the compressed air
– Longer servie life of the oil filters, activated carbon filters and oil separators
– Low formation of oxidation residues in the oil circuit, reduced operating costs due to extended oil filter and separator life



Klüber Summit SH oils are air compressor oils based on synthetic hydrocarbon and additives. They can be mixed with mineral oils and synthetic hydrocarbon oils, however are not miscible with polyglycol oils.



Klüber Summit SH oils have been designed especially for the lubrication of highly loaded, oil-injected screw-type compressors with oil change intervals up to 10,000 operating hours.

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

Klüber Summit SH 32 is especially suitable for centrifugal compressors and Klüber Summit SH 100 for reciprocating piston compressors.

Klüber Summit SH oils offer good oxidation stability due to the synthetic base oil, thus minimizing oxidation residues in the compressors and extending oil change intervals and the service life of oil filters and separators. Special inhibitors contained in the oils keep the inside of compressors clean.

Owing to the evaporation stability of the base oil, the oil vapour content in the compressed air can be considerably reduced compared to conventional mineral oils. This contributes to a reduction of oil consumption and clean compressed air; gumming of pneumatic valves in the compressed air circuit can be prevented as well due to the low oil content of the Klüber Summit SH oils.

Application notes


When selecting the oil viscosity for air compressors please observe the manufacturers’ instructions.
When switching a used compressor to a Klüber Summit SH oil, drain old oil from whole circuit of compressor while still warm.
We also recommend changing all oil filters and separators. Then refill the compressor with Klüber Summit SH oil.
When switching from mineral oil to a synthetic Klüber Summit SH 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 SH oil, the compressor should be cleaned using the Klüber Summit Varnasolv conditioner (cf. product information leaflet).
Your contact persons at Klüber Lubrication would be pleases to provide further information.

After switching to a Klüber Summit SH oil we recommend determining the oil change interval through an oil analysis or the Klüber Summit TAN Kit.
