Description
Description
The Castrol Aricol™ 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 oil), 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 oil 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 90°C. The product has been designed to meet service drain intervals of up to 4,000 hours. For intermittent or continuous operation with air discharge temperatures above 90°C 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 Aricol 32 and 46 are suitable for oil flooded rotary compressors, whereas Aricol CM 68, CM 100 and 150 would be selected for lubricating the crankcase and cylinders of reciprocating compressors.
The Aircol CM range is fully compatible with Castrol Aircol PD and MR ranges.
Advantages
- Good water separation characteristics allows condensation to readily separate from the oil, minimising the risk of emulsions which could block the oil separator element.
- Fully inhabited against corrosion which enables protection even when operating under humid conditions.
- Good thermal stability, low volatility and low carbon formation reduces the risk of fire and explosion and leads to a longer operating life (up to 4000 hours)
- Low deposit forming tendencies extends oil change intervals and provides longer air filter life which contributes to a reduction in maintenance costs.
- Excellent coalescing properties mean little carrying oil in the air steam.
- High load carrying to meet requirements of geared compressor units
