- Klüber Summit HySyn oils can be used for oil-injected screw-type compressors, reciprocating piston compressors and centrifugal compressors.
- Klüber Summit HySyn FG oils are intended for use in compressors of the food-processing and pharmaceutical industry requiring oil-free compressed air (without oil vapour which cannot be removed by the oil separator).
- Klüber Summit HySyn FG oils can also be used for the lubrication of gears in oil-free screw-type compressors. Owing to their good stability, these oils are also suitable for lowtemperature applications in industrial gears. Furthermore, Klüber Summit HySyn FG 32-46-68 oils are used in chains, particularly those operating at low temperatures, e.g. in freezing tunnels.
- When selecting the oil viscosity for air compressors, please observe the manufacturers' instructions.
- For oil-injected screw-type compressors normally the viscosity grades ISO VG 32, 46 and 68 are used, for reciprocating piston compressors ISO VG 68 and 100 and for centrifugal compressors ISO VG 32.
- In addition Klüber Summit HySyn FG 68 can be used for the IS machine plunger lubrication in the glass industry. Notes on switching from mineral to synthetic oils : When switching a used compressor to a Klüber Summit HySyn FG 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 HySyn FG oil. When switching from mineral oil to a synthetic Klüber Summit HySyn FG 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 HySyn FG oil, the compressor should be cleaned using the Klüber Summit Varnasolv conditioner (cf. product information leaflet).
- After switching to a Klüber Summit HySyn FG oil we recommend determining the oil change interval through an oil analysis or the Klüber Summit TAN Kit after approx. 500 to 1000 operating hours. Your contact person at Klüber Lubrication would be pleased to provide further information.
