Compressor Compact

4. Air outlet section

4.1 Compressed air reservoir
The COMPRESSED AIR RESERVOIR is a
plastic container with a volume of approx.
1.8 liters.
4.2 Pressure manometer
A PRESSURE MANOMETER is connected
to the 4.1 COMPRESSED AIR RESERVOIR.
This manometer shows the air pressure in
the reservoir. The manometer has the range:
• 0 – 6 bar in older versions of the
Compressor Compact.
• 0 – 10 bar in newer versions of the
Compressor Compact.
4.3 Moisture relief valve
The MOISTURE RELIEF VALVE is
connected to the bottom of the 4.1 COM-
PRESSED AIR RESERVOIR with a plastic
tube. This valve is a spring-loaded valve that
is provided to drain the air reservoir if water,
for some reason, collects in the reservoir.
The valve pin must be pushed manually to
drain the air reservoir.
4.4 Compressed air outlet
The COMPRESSED AIR OUTLET is
connected directly to the 4.1 COMPRESSED
AIR RESERVOIR. It consists of a female
(AGA standard) quick-coupling and a hose
nipple for an 8 mm hose.
The test nozzle attached to the compressor
must be used when performing functional
checks or troubleshooting on the
Compressor Compact. It provides a
simulated load that permits rapid, easy
checks of the output pressure.
E382 EH81E 061 01 03 02
When testing the Compressor Compact, the
test nozzle should be connected to this outlet
so that compressed air flows through the
nozzle. Output pressure can then be read off
from the pressure manometer.
The test nozzle permits an air flow that is
higher than 40 l/min. For this reason the air
pressure in the system may not reach the
stated 400 kPa (4 bar) when the test nozzle
is connected. An air pressure of 400 kPa
±50 kPa (4.0 bar ±0.5 bar) indicated on the
manometer shows that the compressor is
operating correctly.
4.5 Compressed air inlet
Compressors with standby function are
equipped with a COMPRESSED AIR INLET.
This air inlet is connected to the 4.1 COM-
PRESSED AIR RESERVOIR via the
3.6 STANDBY SOLENOID VALVE. The
purpose of the air inlet is to provide com-
pressed medical grade air from the hospital
central gas supply to the air reservoir.
The inlet nipple must be adapted to local
standards. The inlet hole in the reservoir is
provided with a 12 x 1 mm thread.
The standby function is further described in
section 5.7 STANDBY LAMP.
4.6 Cooling air outlet
The forced cooling air stream provided by
the 3.14 FAN in the dryer section exits from
the compressor via the COOLING AIR
OUTLET. The air outlet is covered with foam
rubber to reduce the noise of the air stream.
