Castrol Aircol SN air compressor lubricants are diester based synthetic lubricants with excellent oxidation resistance and low carbon-forming tendency.
Castrol Aircol SN compressor lubricants were developed to cope with the severe operating conditions experienced in reciprocating air compressors operating at high compression ratios and high discharge temperatures of up to 220ºC. Under these conditions Aircol SN compressor lubricants offer much reduced carbon-forming tendencies and extended oil life when compared to mineral oils due to their much higher oxidation resistance. Whilst Aircol SN 68 was primarily intended for the crankcase and cylinders in reciprocating air compressors, it may also be used in certain types of turbochargers, where it will provide significant in-service benefits when compared with mineral based lubricants.
- Superior oxidation stability.
- Improved lubricity and film strength.
- Higher film strength and excellent anti-wear properties.
- Excellent high temperature performance.
- Reduced maintenance, extended oil life and cleaner operations, minimizes carbon formulation and provides extended valve life.
- 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.
- Reduced compressor down-time due to less wear on all moving parts, longer machine life and reduced maintenance.
- 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.
All packages should be stored under cover. Where outside storage is unavoidable drums should be horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60ºC, exposed to hot sun or freezing conditions.
