Refrigeration Oils

Castrol Aircol 266

VISCOSITY - 30 mm/s² at 40°C

Mineral Refrigeration Compressor Oil

DESCRIPTION

The Castrol Aircol™ 266 & 299 range of mineral based refrigeration oils is available as two grades of specially selected
oils, highly refined, to provide chemical and thermal stability. Their low wax forming tendencies insure low pour points.

APPLICATIONS

Aircol 266 & 299 are specifically for use in refrigeration and air conditioning plants using fluorocarbon refrigerants. The
exceptional low temperature characteristics of these oils prevent the flocculent precipitation of wax which can otherwise
occur in high performance plant using Freon refrigerants.
In most systems using R22, the critical solution temperature characteristics of these oils are adequate to prevent oil/
refrigerant separation problems within the low temperature circuits. Where evaporation temperatures are exceptionally
low or in systems not incorporating oil/refrigerant separators, synthetic base refrigerant oils may be preferred.
