3. COMPONENTS

4. Compressor
Compressed air supply: Delivery
Air reservoir
Supply taken from top of ring main
Intermediate reservoir
Service unit
Condensate
collector tank
Reservoir within a pneumatic system
1-2 % gradient
Consuming
devices

5.  Compressor fills the reservoir – as storage
tank
 Pipeline is installed with a gradient of 1 to 2 %
 Condensate removal are installed under the
main pipeline

6.  Function: Control the pressure or flow rate of
pressure media
 Categories:
◦ Directional control valves
◦ Non-return valves
◦ Flow control valves
◦ Pressure control valves
◦ Shut-off valves
