Synthetic Air Compressor Lubricant
DESCRIPTION
Castrol Aircol SN compressor lubricants are high quality synthetic diesters.

APPLICATION
Castrol Aircol SN compressor lubricants were developed to cope with the severe operating conditions experienced in rotary screw, rotary vane and reciprocating air compressors operating at high compression ratios and high discharge temperatures.  Under these conditions Aircol SN compressor oils offer much reduced carbon forming tendencies and extended oil life when compared to mineral oils due to their much higher oxidation resistance.In reciprocating units, Aircol SN grades have up to eight times the service life of mineral oils.

FEATURES BENEFITS
S  Superior oxidation stability , S  Reduced maintenance, extended oil life and cleaner operations, minimises carbon formulation and provides extended valve life.
S  Improved lubricity and film strength S  Reduced oil consumption due to a reduction in the feed rate to the cylinder walls and piston rings without increasing wear rates.  Since less lubricant is consumed the downstream air is also of higher quality.
S   Higher film strength and excellent anti-wear properties S  Reduced compressor down-time due to less wear on all moving parts, longer machine life and reduced maintenance.
S   Excellent high temperature performance S  Due to their the operating range of Aircol SN grades extends well beyond that of conventional mineral oils.  The high spontaneous ignition temperature gives greater safety by reducing the possibility of downstream fires and explosions.

COMPATIBILITY OF AIRCOL SN

Mineral Oils
Aircol SN grades are compatible with conventional non-detergent mineral oils such as the Aircol PD series.  Contamination with detergent compressor or engine oils, or automatic transmission fluids as are recommended for certain types of compressor can lead to foaming, filter plugging or sludge formation.
Seal Material
Certain types of seals used with conventional mineral oils can produce excessive swelling if used with synthetic fluids.  A list of suitable seal materials listed on Page 3.
Plastics
Polycarbonate filter and lubricator housings should not be used with synthetic diester fluids and should be replaced with metal components.  A list of suitable plastics is given on Page 4.
Gases
Aircol SN lubricants can be used for the compression of a wide range of gases in addition to air.  A list of acceptable and incompatible gases is given on Page 3.
Paints

Metals
