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

Application：
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)

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 inhibited 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 2000 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 carry over of oil in the air stream.
