The Castrol AircolTM MR compressor oil range of premium lubricants are formulated from highly refined mineral oils
and novel additive technology to give outstanding antiwear and antirust performance to meet the requirements of Atlas
Copco and similar types of compressor design.

Aircol MR incorporates a carefully balanced antioxidant system providing improved oxidative and thermal stability giving
“extended” service life for both oil flooded and oil injected rotary screw compressors operating continuously at air
discharge temperatures up to 90ºC. The product has been designed to meet service drain intervals of 4000 hours. For
intermittent or continuous operation with air discharge temperatures above 90ºC the manufacturers’ standard oil change
periods should be used.
The Aircol MR range is fully compatible with nitrile, silicone and fluropolymer seal materials.

Aircol MR is classified as follows:

• ISO 6743-3 Compressor Oils
• DAG and DAH for rotary air compressors

Aircol MR grades meet the requirements of:

• Atlas Copco for 4000 hour oil life.

• Very low deposit forming tendencies extends oil change intervals and air filter life which contributes to a reduction
  in maintenance costs.
• Good air/oil separation properties at the separator element reduces risk of oil carry over.
• Good antiwear protection reduces rotor wear.
• Excellent water separation characteristics allows condensation to readily separate from the oil, minimising the
  risk of emulsions which could block the oil separator element.
• Excellent oxidation and thermal stability minimises oil thickening and extends the oil separator life and reduces
  fouling of coolers & pipes.
• Prevents corrosion when operating under humid conditions.
