Air compressor Oil 68

Application

These products are ashless oils recommended for the lubrication of rotors, bearings and gears in rotary compressors, specially 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.
It can be used for either normal or severe duty lubrication of reciprocating and rotary drip-feed air compressors.
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)
Behsan compressor oils exhibit low carbon forming tendencies and meet the requirements for reciprocating compressors having air discharge temperatures up to 220°C.
Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation however as a general guide
Behsan air compressor oil grade 32 and 46 are suitable for oil flooded rotary compressors, whereas Behsan air compressor oil grade 68 and 100 would be selected for lubricating the crankcase and cylinders of reciprocating compressors. Behsan air compressor oil 150 is recommended for sliding-vane compressors, or for reciprocating units at high ambient temperatures.

Advantages

Good water separation characteristics allows condensation to readily separate from the oil, minimizing 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.
