Aircol SN
Synthetic Air Compressor Oils


I N T R O D U C T I O N

Castrol Aircol SN air compressor lubricants are
formulated using high quality synthetic ester base
stocks with an additive system designed to enhance
thermal and oxidation stability and reduce component
wear.
The products are primarily intended for use in
reciprocating air compressors. However they
may be used in certain types of turbocharger,
where they will provide significant in-service
benefits when compared with mineral based
lubricants.


FEATURES AND BENEFITS


The performance of Castrol Aircol SN compressor
oils offer the following specific benefits:
v Less maintenance
                          v Extended crankcase drain periods
v Cleaner operation
These results from the superior oxidation stability of
Castrol Aircol SN, which minimises carbon build up
and provides extended valve life. In reciprocating
units, the Castrol Aircol SN grades can last up to
eight times longer than mineral oils.
Improved lubricity and film strength allows for a
reduction in the feed rate to the cylinder walls and
piston rings with no detrimental effect. Since less
lubricant is consumed, the downstream air is of
higher quality. Reduced compressor downtime,
higher film strength and excellent anti-wear properties
mean less wear on all moving parts, providing for a
longer machine life expectancy and less repairs.
Easier start-up operation. Castrol Aircol SN has
improved low temperature performance, its low
pour point allowing for easier initial circulation.
The low frictional properties and high film
strength of Castrol Aircol SN lead to improved
efficiency and marginally lower power
requirements.
Castrol Aircol SN's high auto ignition
temperature gives greater safety by reducing the
possibility of downstream fires and explosion
