SUMMIT DSL

Fully synthetic air compressor oils for oil change intervals up to 8,000 operating hours.

Klüber Summit DSL oils are air compressor oils based on a synthetic ester oil and additives. They can be mixed with mineral oils, synthetic hydrocarbon oils and polyglycol oils.

The Klüber Summit DSL 32 … 68 oils have been especially designed for oil change intervals up to 8,000 operating hours* in oil-injected screw-type compressors. Klüber Summit DSL 32 and 46 can also be used for the lubrication of centrifugal compressors, whereas Klüber Summit DSL 68 ... 150 is particularly suitable for the lubrication reciprocating piston compressors.
Klüber Summit DSL oils are used for compressors that were previously run with conventional mineral oils. These oils are neutral towards most elastomer seals used in air compressors, therefore leakage is not to be expected.
Klüber Summit DSL oils are mainly used in reciprocating piston compressors which do not achieve the desired maintenance intervals when using mineral oils or which show severe residue formation (carbon buildups) on valves and in the compression chamber. Klüber Summit DSL 32, 46, and 68 are biodegradable and can therefore be used in eco-sensitive applications.
Klüber Summit DSL 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 (screw-type compressors) and valves (reciprocating piston compressors).
When selecting the oil viscosity for air compressors please observe the manufacturers' instructions.
When switching a used compressor to a Klüber Summit DSL 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 DSL oil.
When switching from mineral oil to a synthetic Klüber Summit DSL 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 DSL oil, the compressor should be cleaned using the Klüber Summit Varnasolv conditioner (cf. product information leaflet).
Your contact persons at Klüber Lubrication would be pleased to provide further information.
After switching to a Klüber Summit DSL oil we recommend determining the oil change interval through an oil analysis.

Low maintenance and operating costs due to oil change intervals up to 8,000 operating hours inoil-injected screw-type compressors
Easier compressor oil conversion due to neutral behaviour of oils towards seals
Good soil dissolving capacity, clean oil circuit due to the ester content in the oil, reduction of cleaning costs
Low formation of oxidation residues in the oil circuit, reduced operating costs due to extended oil filter and separator life
Klüber Summit DSL 32, 46, and 68 are biodegradable oils and can be used for sensitive applications like sewage plants
Surpasses the requirements of DIN 51506-VDL and ISO 6743-3 L-DAJ (VG 32/46/68) / L-DAB (VG 100/150)
