CASTROL AIRCOL PD 68

Castrol Aircol PD oils are a range of compressor oils, based upon highly refined mineral oils, which are intended for the lubrication of both reciprocating and rotary air compressors.

Aircol PD grades are ashless oils recommended for the lubrication of rotors, bearings and gears in rotary compressors, especially the oil flooded screw type with lubricant drain cycles of up to 2000 hours under normal use.

Normal use in screw type compressors is defined by a maximum air discharge temperature =/< 100°C as defined by ISO 6743-3:2003. Aircol PD can be used for either normal or severe duty lubrication of reciprocating and rotary drip-feed air compressors, as defined by ISO 6743.

Normal duty is described as:-

• discharge temperatures =/< 165°C
• differential pressures =/< 2.5 MPa (25 bar)
• discharge pressures =/< 7.0 MPa (70 bar).

Severe Duty is described as:-

• discharge temperatures > 165°C
• differential pressures > 2.5 MPa (25 bar)
• discharge pressures > 7.0 MPa (70 bar)
