Castrol Tribol™ CS 890 (previously called Tribol 890 Range) compressor oils are fully synthetic ester based lubricants formulated for long service life and clean deposit-free operation. They are manufactured in several viscosity grades to satisfy the lubrication needs of the most demanding air compressor applications (as well as many other process gases).
Rotary vane and rotary screw compressors: Tribol CS 890/32 and 890/68 are designed for vacuum pumps and rotary compressors where circulation systems inject oil directly into the air stream to lubricate, cool and seal the compressor.
The Tribol CS 890 range performs better than petroleum oils in flooded rotary vane and screw compressors. By minimizing varnish and carbon deposits, it can extend drain intervals from 1,000 hours to more than 5,000 hours in most vane compressors. Under normal use oil-flooded screw compressor drain intervals can be extended to over 8,000 hours with maximum air discharge temperatures <100°C, as defined by ISO 6743-3:2003. Tribol CS 890 can also be used in compressor units operating under severe conditions with maximum air discharge temperatures of >100°C with reduced oil drain intervals.
Reciprocating compressors: Tribol CS 890/100 is used for both crankcase and upper cylinder lubrication in reciprocating compressors for either normal or severe duty lubrication, as defined by ISO 6743.
Hydraulic and circulating systems, gears, bearings: where rust and oxidation inhibited (R&O) turbine type circulating oils are specified. Tribol CS 890 is particularly well suited where operating temperatures ranges are too extreme for petroleumbased oils. Tribol CS 890 is classified as follows: DIN 51506 classification - VBL, VCL and VDL. ISO 6743/4 - DAG, DAH and DAJ for rotary air compressors also DAA, DAB for trunk pistons at high pressure and high temperature (Viscosity grade 100).
