Product information

Safety is always a priority for the food-processing, cosmetics, pharmaceutical and animal feed industries --- and this applies to lubricants, too. KLÜBER SUMMIT HYSYN FG 46 is a high-quality air compressor oil that meets the stringent safety and hygiene requirements of these unique industries.

With FDA 21 CFR § 178.3570 compliance, HSF H1 registration, and ISO 21469 certification, KLÜBER SUMMIT HYSYN FG 46 was developed to account for incidental contact with products and packaging materials in these industries, improving the reliability of your production processes.

Based on synthetic hydrocarbon oils, it is miscible with mineral oils and other synthetic hydrocarbon oils. Since it is also highly compatible with common seal materials, converting your compressor oil from mineral oils to KLÜBER SUMMIT HYSYN FG 46 is easy and hassle-free.

Moreover, KLÜBER SUMMIT HYSYN FG 46 offers good oxidation stability due to its synthetic base oil, minimizing oxidation residues in your compressors. A low evaporation tendency also enables it to minimize any impact of the oil vapour on the compressed air. Expect extended oil change intervals --- up to 4,000 operating hours in oil-injected screw-type compressors --- and longer service lives of your oil filters and separators.

KLÜBER SUMMIT HYSYN FG 46 is also suitable for the lubrication of gears due to its high scuffing load capacity. It is used and endorsed by brands around the world like Aerzener, Air Liquide, Boge, CompAir, Worthington, Getriebebau Nord, and Lenze.

Directions for use

KLÜBER SUMMIT HYSYN FG 46 is suitable for use in oil-injected screw-type compressors, reciprocating piston compressors and centrifugal compressors. It was specially developed for the food-processing and pharmaceutical industries requiring oil-free compressed air.

You may also use KLÜBER SUMMIT HYSYN FG 46 to lubricate gears in oil-free screw-type compressors. Due to its good stability, it is suitable for low-temperature applications in industrial gears.

If you are switching your used compressor from mineral oil to KLÜBER SUMMIT HYSYN FG 46, drain the old oil from the whole circuit of the compressor while it is still warm.

We recommend changing all oil filters and separators before refilling the compressor with KLÜBER SUMMIT HYSYN FG 46.
