CASTROL TRIBOL
®
890™
Synthetic compressor oils
DESCRIPTION
CASTROL TRIBOL
®
890 compressor oils are fully synthetic lubricants formulated for long service life and clean deposit-free
operation. They are manufactured in several viscosity grades to satisfy the lubrication needs of essentially all air compressors
and compressors of many other process gases as well.
CASTROL TRIBOL
®
890/32, 890/46 and 890/68 for rotary compressors and vacuum pumps
CASTROL TRIBOL
®
890/100 for reciprocating compressors, vane compressors and vacuum pumps
· The base fluids in CASTROL TRIBOL
®
890 are made form polyol and dibasic-acid ester, synthesized and blended
specifically to optimize properties vital to good compressor operations. They have a natural stability against
decomposition and oxidation at high operating temperatures and thus a low tendency to form lacquers or deposits. The
synthetic base fluids also have very low volatility and high flash and self-ignition temperatures.
· CASTROL TRIBOL
®
890 oils are designed for excellent natural oil film strength and lubricity and are additionally
formulated with load carrying, antiwear additives. An advanced technology additive system also enhances oxidation
stability, inhibits foaming and protects against corrosion. CASTROL TRIBOL
®
890 oils re not corrosive to either ferrous or
non-ferrous metals.
APPLICATIONS
· Rotary vane and rotary screw compressors: where circulation systems inject oil directly into the air stream to lubricate,
cool and seal the compressor, CASTROL TRIBOL® 890/32, 890/46 and 890/68 perform 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 and sometimes to well over 8,000 hours in flooded
screw compressors.
· Reciprocating compressors: CASTROL TRIBOL® 890/100 is used for both crankcase and upper cylinder lubrication in
reciprocating compressors. Crankcase drain intervals can be greatly extended and significant reduction ins valve
inspections and cleaning are possible. Lower volatility permits lower feed rates to reduce carryover and deposit formation.
· Hydraulic and circulating systems, gears, bearings: wherever rust and oxidation inhibited (R&O) turbine type of circulating
oils are specified. CASTROL TRIBOL® 890 is particularly well suited where operating temperatures and ranges are
extreme or marginal for petroleum oils.
ADVANTAGES
· In rotary vane and rotary screw compressors: lower volatility means less oil contamination of plant air, greater demister
efficiency, less maintenance of filters and separators and reduced oil consumption.
· Superior oxidation stability and natural cleansing action prevent the formation and buildup of varnish, sludge or deposits.
This minimizes wear and maintains clearances for maximum compressor efficiency and for optimum cooling and sealing.
· In single or multiple-stage reciprocating compressors: formation and buildup of varnish and carbon deposits are all but
eliminated to prevent valve wear or sticking which allows recompression and provides clean intercoolers. The resulting
benefits are less heat generation and reduced fire potential as well as reduced energy input required for constant
discharge capacity and overall improved compressor efficiency.
· General advantages in all operations:
· Greatly extended oil life in circulation systems and crankcases – 4 to 8 times longer than petroleum oils.
· Lower maintenance and labor costs incurred from less frequent oil change, filter and accessory service, inspection and
removal of deposits and parts replacement.
· Improved profits from fewer production interruptions.
· Year-round service from a single product with extreme low and high temperature range.
· Compatibility with virtually all seals and construction materials used in modern compressor system.

Notes for use
· Changeover from petroleum oils to CASTROL TRIBOL® 890 should always be preceded by a very thorough cleanout. Although 890 oils are compatible with petroleum, any residual mineral oil will soon oxidize
and contaminate CASTROL TRIBOL® 890, shortening the anticipated service life.
· CASTROL TRIBOL® 890 oils soften polycarbonate and should not be used with this material.
· Under no circumstances should these fluids be used where neoprene seals and E.P.D.M. elastomers sealing materials are present anywhere in the air system
