Switching on-off a compressed air unit in a compressed air supply generally takes place with an
automatic valve (ball-valve or butterfly valve).
If air is released from the stored large-volume compressed air supply, and when the compressed air unit is activated, there is a considerable reduction of incoming pressure, because the volume flow of the compressed air unit doesn´t correspond to the actual compressed air requirement. This situation can lead to overloading at the compressed air unit.
Air-main charging systems such as PCS ensure
