(3) Compressed air outlet
Full-Feature units are fitted with an integrated refrigerant dryer (ID, 200), a desiccant dryer (CD,
117) is optionally available.
Air flow
Air drawn through the air filter (100) is compressed by the compressor element (101). Next, the
compressed air flows through the check valve (105) and the air cooler (106).
Single phase units are equipped with a solenoid valve (109) and a silencer (110) for easy starting at
low voltage.
On floor-mounted, Pack units the air then flows directly to the outlet valve (121). On tank-mounted
units, the compressed air flows into the air receiver (120), onto which the outlet valve (121) is fitted.
On Full-Feature units, the compressed air flows to the refrigerant dryer (ID, 200), where the water
vapor condensates by cooling down. The water is removed via the integrated water separator
(201c) and the electronic drain (210).
The compressed air flows to the refrigerant dryer (ID, 200), where the water vapor condensates by
cooling down. The water is removed via the integrated water separator (201c) and the electronic
drain (210).
For details on the operation of the refrigerant dryer (ID, 200), see section Refrigerant dryer.
On Full-Feature compressors equipped with a desiccant dryer (CD, 117), the air from the refrigerant
dryer (ID, 200) passes a PD 20
+
filter (114) and flows into the desiccant dryer (CD, 117). Next, the
dry air flows into the receiver (120).
For details on the operation of the desiccant dryer (CD, 117), see section Desiccant dryer.
Cooling
The compressor element (101) is cooled by an integrated radial fan (102). An axial fan (107) fitted
on the motor shaft provides cooling air for the air cooler (106).
