Lubrication
McEnergy units do not require a routine procedure for lubrication of components. The venti lator bearings have
permanent lubrication and no additional lubrication is therefore required.
Compressor oil is of the synthetic type and is highly hygroscopic. It is therefore advised to limit its exposition to the
atmosphere during the storage and loading phases. It is recommended that the oil be exposed to the atmosphere for no
more than 10 minutes.
The compressor oil filter is positioned under the oil separator (delivery side). Its replacement is advised when its pressure
drop exceeds 2.0 bars. The pressure drop through the oil filter is the difference between the compressor delivery
pressure and the oil pressure. Both these pressures can be controlled through the microprocessor for both compressors.
