Castrol Aircol CM
Mineral Refrigeration Compressor Oil
Product Description
The Castrol Aircol™ CM compressor oil range of high-quality lubricants are based upon highly refined mineral oil, enhanced with additive technology providing excellent thermal and oxidative stability and good load carrying capacity, compared to other products in the same class.
Application
Aircol CM grades are formulated without zinc additives (ashless oils), recommended for the lubrication of rotary screw and reciprocating compressors.
Aircol CM is classified as follows:
ISO 6743-3 Compressor Oils
DAA and DAB for reciprocating (piston) and drip freed rotary air compressors
DAG and DAH for oil-flooded rotary screw air compressors Aircol CM compressor oils exhibit low carbon forming tendencies and meet the requirements of the DIN 51506 VDL classification for reciprocating compressors having air discharge temperatures up to 220°C. 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 up to 4000 hours. For intermittent or continuous operation with air discharge temperatures above 90ºC the manufacturers’ standard oil change periods should be used. The high FZG load carrying is designed also to meet geared compressor units. Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation.
However, as a general guide Aircol CM 32 and 46 are suitable for oil flooded rotary compressors, whereas Aircol CM 68, CM 100 and 150 would be selected for lubricating the crankcase and cylinders of reciprocating compressors. Aircol CM 150 is also recommended for sliding-vane compressors, or for reciprocating units at high ambient temperatures. The Aircol CM range is fully compatible with Castrol Aircol PD and MR ranges
