The invention relates to a compressed air generating device (2.1) comprising a control and regulating device (28), at least one controllable and regulatable electric motor (24), at least one air compressor (16, 18) which can be driven by the electric motor (24), an air inlet (8) via which surrounding air (L) can be suctioned into the at least one air compressor, at least one air cooler (20, 22) which is connected to the outlet of the at least one air compressor, an air dryer (40), the inlet of which is connected to the outlet of the at least one air cooler, a coolant inlet opening (12*) via which a liquid coolant can be supplied to the at least one air cooler and other components of the compressed air generating device, and a coolant outlet opening (14) via which heated coolant can be discharged out of the compressed air generating device. In order to design the compressed air generating device to be as compact as possible and inexpensive to produce, the control and regulating device (28) is designed and arranged such that the control and regulating device can be used to control and regulate the operation of the electric motor (24), a drying operation, and a regeneration operation of the air dryer (40) as well as the operation of a multi-circuit protection valve (50), and coolant can flow through the air cooler (22) first when viewed in the flow direction of the coolant, said air cooler being arranged in front of the air dryer (40) as the last air cooler in the flow direction of the compressed air. The invention also relates to a method for operating said compressed air generating device.
