April 2018
The Castrol Aircol SR compressor oil range of premium lubricants are designed for use in rotary screw compressors
and are based on polyalphaole n (PAO) uids.
Application
Castrol Aircol SR is suitable for use in oil ooded rotary screw compressors operating under extreme climatic
conditions, harsh environments and severe operating conditions where very high air discharge temperatures (> 100°C)
are experienced.
These oils are also suitable for use in compressor units operating at normal operating conditions, with the maximum
air discharge temperature =/< 100°C, as de ned by ISO 6743-3:2003.
For normal operating conditions, these products can be used for extended drain intervals up to 8000 hours.
The Castrol Aircol SR range is fully compatible with nitrile, silicone, polyurethane and uropolymer seal materials
typically used in compressor units. It is not compatible with butadiene styrene (SBR) or ethylene propylene (EPDM)
seals.
Features and Bene ts
Castrol Aircol SR is a PAO based lubricant offering good compatibility with seals and mineral oil based lubricants and
allowing changeover to Aircol SR without compatibility issues. Castrol Aircol SR offers the following bene ts:
• Increased oil service life of typically up to 8000 hours in most systems, depending on the
operating environment.
• Very low deposit-forming tendency, thus extending the service life of lters and separators.
• Outstanding oxidation stability and antiwear performance, providing long lubricant and equipment life.
• Ester-free formulation that eliminates the formation of corrosive acids leading to longer equipment life.
• Excellent water separation characteristics, allowing condensation to readily separate from the oil.This minimizes
the risk of emulsions, which could block the oil separator element.
Classi cations
Aircol SR is classi ed as follows:
• DIN 51506 classi cation - VDL
• ISO 6743/3 - DAG, DAH and DAJ for rotary air compressors
Aircol SR grades meet the requirements of:
• Atlas Copco 8000 hour oil drain interval
• Kaeser
