The Castrol Aircol® SR compressor oil range of premium lubricants are designed for use in rotary screw compressors and are based on polyalphaolefin (PAO) fluids. It is suitable for operation 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 defined by ISO 6743-3:2003.
Characterized by extreme pressure and rust and corrosion protection, Castrol Magna® RD provides tackiness for adherence to drill surfaces. In tests by Ingersoll-Rand and Gardner-Denver laboratories, it has shown to exceed their requirements.
Castrol Magna® SW D is specially formulated for the lubrication of slideways on machine tools. These oils are fortified with selected oiliness, extreme pressure additives and a special material to impart tackiness and adhesiveness. These lubricants are noted for their usual ability to overcome the stick-slip motion ordinarily associated with slow-moving tool parts. These oils reduce machine-tool-carriage chatter and possess the necessary adhesive characteristics to prevent squeezing out of the lubricant.
Very stable paraffinic base oils are fortified with high-temperature oxidation-inhibitors to offer excellent circulation during cold-weather startups, eliminate overheated pump motors, and protect against hot spots (high fluid temperature in the heat exchanger).
