The Aircol PD range of compressor oils are based on highly refined mineral oils and carefully chosen additives.
They are intended for the lubrication of rotary and reciprocating compressors. 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)
Aircol PD 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.
