GS Compressor P are recommended for stationary and portable compressors, operating at compression temperatures up to 220°C including compressors with oil lubricated pressure space,e.g. single and multistage reciprocating compressors or single or multistage centrifugal compressors.The 46 grade is primarily recommended for use in oil-flooded screw compressors as well as centrifugal compressors. At high compression pressures, such as in multistage reciprocating compressors,the higher viscosity grade may be used. GS Compressor Oil EP-VDL has been tested and approved by “Rheinische-WestfälischerUberwachungsverein e.V.” in Germany and it meets DIN51 506 VDL.
