INDUSTRIAL LUBRICANTS


Compro™ – Air Compressor Fluids

COMPRO™ Compressor Fluids are ashless air compressor fluids formulated to provide long and highly reliable service life in industrial air compressor applications. COMPRO™ Fluids are available in 32 and 68 viscosity grades (for additional grades see COMPRO™ XL-S). They are suitable for use in compressors that handle air, and inert gases such as nitrogen, argon, hydrogen, neon, helium, carbon dioxide, carbon monoxide and blast furnace gas.

COMPRO™ Fluids can be used in rotary screw compressors to a maximum of 2,000 hours at air discharge temperatures up to 85°C/185°F, in centrifugal compressors for up to two years at air discharge temperatures up to 50°C/122°F, and in reciprocating compressors for shorter duration. COMPRO™ 68 meets the requirements of DIN 51506 VDL.

Air compressors in continuous service or operating at elevated discharge temperatures should use COMPRO™ XL-S and COMPRO™ Synthetic for extended life.

NOTE 1: Do not use in breathing air apparatus or medical equipment. COMPRO™ air compressor fluids should never be used in any equipment compressing pure oxygen. Please note that in the case of chemically active gases such as chlorine, oxygen and hydrogen chloride, no petroleum lubricant is recommended.

NOTE 2: Consult Tech Bulletin “TB-1217 - Guidelines for Converting to COMPRO™ Compressor Fluids” before changing over to any of the COMPRO™ fluids.

COMPRO™ XL-S Compressor Fluids are formulated to extend compressor fluid life in rotary screw air compressors, with minimal carbon deposits or varnish formation.

COMPRO™ XL-S is particularly recommended for air compressors in continuous service operating at discharge air temperatures up to 85°C/185°F. Such rotary screw compressors may be run for up to one year (8,000 hours) in continuous operation. This is at least four times the life of conventional mineral oil based compressor fluids.

While particularly effective in rotary screw compressors, COMPRO™ XL-S can also be used in centrifugal compressors for up to three years at air discharge temperatures up to 50°C/122°F. COMPRO™ XL-S 68, 100 and 150 meet the requirements of DIN 51506 VDL, and can be used in reciprocating compressors for shorter duration.

Note: Do not use in breathing air apparatus or medical equipment. COMPRO™ XL-S air compressor fluids should never be used in any equipment compressing pure oxygen. Please note that in the case of chemically active gases such as chlorine, oxygen and hydrogen chloride, no petroleum lubricant is recommended.

COMPRO™ Synthetic is a premium fluid that has been specifically developed for rotary screw air compressors operating in severe service environments, particularly those with high air-discharge temperatures up to 105°C/221°F. COMPRO™ Synthetic outperforms PAO synthetic based fluids at these high discharge temperatures - up to one year continuous service or 8,000 hours. (NOTE: This is a Polyalkylene Glycol / Ester blend and should never be mixed with mineral oils or Polyalphaolefin synthetics.)

Note: Do not use in breathing air apparatus or medical equipment. COMPRO™ Synthetic air compressor fluid should never be used in any equipment compressing pure oxygen. Please note that in the case of chemically active gases such as chlorine, oxygen and hydrogen chloride, COMPRO™ Synthetic must not be used.

COMPRO™ E Compressor Fluids are fully synthetic, high performance ester based lubricants formulated to provide superior protection in rotary screw, rotary vane, centrifugal, and reciprocating air compressors*.

COMPRO™ E Fluids are recommended for single and multistage air compressors, such as rotary vane compressors, rotary screw compressors, reciprocating compressors, and centrifugal compressors. Please note that not all viscosity grades are suitable for all compressor types; please follow compressor OEM recommendations and follow the operation manual of the specific brand and model of compressor. COMPRO™ E Compressor Fluids are ester based fluids that are compatible with mineral oil products.

COMPRO™ E Fluids are compatible with standard rubbers/elastomers used in most compressor components:

Recommended to use with Teflon, Viton, High Nitrile Rubber-Buna N (>36% nitrile content). Fair compatibility with Nitrile Rubber-Buna N (30%-36% nitrile content), Silicone Rubber, Ethylene-Propylene Terpolymer, Polyacrylate Rubber, and Epichlorohydrin. Not recommended to use with Natural Rubber, Neoprene, Nitrile Rubber, Butyl Rubber, and Styrene.

COMPRO™ E Fluids are compatible with the following standard paints and coating used in most compressor components:

Recommended to use with Epoxy, Baked Phenolic, Oil Resistant Alkyd, Cured (moisture) Urethane.

Fair compatibility with Industrial Latex.

Not recommended to use with Acrylic, Vinyl (PVC), Lacquer, Varnish, Latex (household type).

Note: COMPRO™ E Fluids should not be used in systems compressing wet or sour hydrocarbon gases. For these applications, Petro-Canada Lubricants line of natural gas compressor fluids are recommended.

Note: Do not use in breathing air apparatus or medical equipment.

Note: COMPRO™ E Fluids must not be used in the compression of oxygen, or other chemically active gases such as chlorine or hydrogen chloride.

* Not all viscosity grades are suitable for all compressor types, please follow compressor OEM recommendations.
