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-exchang-
er (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
su 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 v-Log (2) which keeps the net pressure
within programmable pressure limits by automatically loading and unloading the compressor
in relation to air consumption.
Main operating mode: Upon start-up, the frequency inverter accelerates the compressor over
15 seconds to the maximum permitted frequency. Pressure builds up to the specied target val-
ue. When it is reached, the compressor maintains the set pressure by varying the current signal
coming from the frequency inverter. If the consumption of compressed air increases, the frequency
coming from the frequency inverter also increases and thus the rotation of the main motor shaft. If
the consumption of compressed air decreases, the frequency coming from the frequency inverter
also decreases. However, the compressed-air pressure remains constant. When the off button is
pressed, the frequency inverter lowers the frequency over 15 seconds to the minimum permitted
frequency and switches off the compressor.
Unloading: If air consumption is less than the air delivered by the compressor, the net pressure
increases. When the net pressure reaches the upper limit of working pressure (unloading
pressure), the solenoid valve (3) is de-energized. The damper (5) of the intake valve (1) closes
the air inlet opening by a spring force:
1. The control pressure present in the chambers of the intake valve (1) and the unloading
valve (7) is vented into the atmosphere via the solenoid valve (3).
2. The damper (5) of the intake valve (1) closes the air inlet opening.
3. The unloading valve (7) is opened by the air-oil separation tank pressure. The pressure
from the air-oil separation tank (4) is released towards the air inlet.
4. The pressure is stabilized at a low value, air output is stopped (0 %) and the compressor
runs unloaded.

11
COMPRAG Screw air compressor DV-Series
Loading: When the net pressure decreases
to the loading pressure, the solenoid valve is
energized:
1. The control pressure is fed from the air-
oil separation tank (4) via the solenoid
valve (3) to the unloading valve (7).
2. The unloading valve (7) closes the
air blow-off opening. The damper (5)
moves backdown and causes the in-
take valve (1) to open fully.
Air output is resumed (100 %), and the
compressor runs loaded.

Installation facility proposal DV11 – DV22
1. Air inflow
2. Air outflow
Ensure that the oor of the facility can withstand the weight of the compressor. Install the
compressor on a level surface that is able to bear its weight. Adjust the horizontal axis of the
compressor using a levelling instrument. If the compressor is not anchored to the base on
which it is installed, the tilt angle with respect to the horizontal surface must not exceed 3°.
If the compressor is anchored to the base on which it is installed, the tilt angle with respect to
the horizontal surface must not exceed 7°. Install the compressor in a facility where precip-
itation cannot reach. Choose a facility for installing the compressor with a minimum level of
dust. Install the compressor at least 1,5 m from walls.
If multiple compressors are installed, there should be a 1,5 m minimum distance between
each compressor. There should be a 4 m safety distance from the area of the operated equip-
ment connected to the compressor.
The facility in which the compressor is installed must be
tted with a combined extract-and-input ventilation system.
The facility where the compressor is installed should be provided
with air inow equivalent to twice the compressor’s capacity.

16 Version 1 .3
3.5 Connection to the compressed airline
Providethe throughputcapacity of the compressed-airline in accordancewith the perfor- mance
of the compressor. In order to avoid damage associated with seal failure of the compressed-air
line, the compressor should be connected via a exible hose. All components of the com-
pressed-airline must have a working pressure no less than the compressor’snominal pressure.
Use a pressure vessel with a capacity corresponding to the compressor’s performance and
the compressed air consumer.
3.6 Connecting to power supply
The compressor is not supplied with a power cable. The cable size must be chosen to ensure
that the maximum voltage drop not exceed 5 % of the nominal voltage value. Cable length
must not exceed 25 m. Ambient temperature in the facility must not exceed 40°C.
The cable must be sheathed with a re retardant compound. An isolating switch must be
tted within reach of the compressor to facilitate connection and maintenance.
The compressor must be earthed and protected against short
cir- cuits in each phase, impermissible voltage uctuation and
phase failure.
The power cable has to be fed into the compressor.
