  "textContent": "A compressed air supply installation includes a compressed air supply, a compressed air port to a pneumatic installation, a vent port to a venting environment, and a pneumatic main line between the compressed air supply and the compressed air port. The pneumatic main line includes an air dryer. The installation further includes a vent valve arranged in the pneumatic main line, the vent valve being a first pilot valve having a pilot control port, a compressor having at least one compressor stage, and a second pilot valve and a pneumatic pilot control channel that pneumatically connects the second pilot valve to the pilot control port of the first pilot valve. A pressure-holding pneumatic valve device is connected to the pilot control port of the first pilot valve and is configured to provide a control pressure for the pilot control port of the first pilot valve.",
