A compressed air supply installation for operating an air suspension installation of a vehicle includes an air supply unit configured to supply air, an air compression unit configured to compress air, a bleeding line, and a compressed air supply line. The bleeding line includes a bleeding valve arrangement in the form of a controllable solenoid valve arrangement comprising a magnetic part and a pneumatic part actuatable directly via the magnetic part, and a bleeding port for bleeding air. The compressed air supply line includes an air dryer, and a compressed air port for supplying the pneumatic installation with compressed air. The pneumatic part is open in an unactivated state of the magnetic part of the solenoid valve arrangement. The pneumatic part is open in a branch line of the compressed air supply line between a pressure-side valve port and a control-side valve port of the branch line.
