2.4 Functional description (see Fig. 2.3)

Air ow:

Air drawn through Air

lter

(4) and open Intake valve (5) into compressor Air-end (3) is compressed.

Compressed air and oil ow into Air-Oil separation tank (6). The air is discharged via Min.

Pressure valve (11) through Heat-exchanger (13) towards the Air Outlet Valve (20).

Oil ow:

Air pressure forces oil from the air-oil separation tank (6) through the heat-exchanger (14)

and the oil lter (16) to the compressor air-end (3) and the lubrication points. In the air-oil

separation tank (6), most of the oil is removed centrifugally; the rest is removed by the

air-oil separator (8).

The oil system is tted with a thermostatic valve (15). When the oil temperature is below

the set-point of the thermostatic valve, the thermostatic valve shuts off the oil

pply

from

oil heat-exchanger (14). The thermostatic valve starts opening the supply from heat-

exchanger (14) when the oil temperature exceeds the valve’s setting. The setting of the

thermostatic valve depends on the model. See table Technical Data.

Cooling system:

The cooling system is a combined radiator consisting of a part for air (13) and a part for oil (14).

The ventilation takes place with a fan with separate electric motor.

2.5

Regulating system

The system is controlled by an electronic controller pro-Log (4) which keeps the net

pressure within programmable pressure limits by automatically loading and unloading the

compressor in relation to air consumption.
