Abstract: A monitoring device (1) for a system for generating medical compressed air includes a measured air line (3) removing compressed air from a compressed air supply line downstream of a compressed air conditioning unit. A sensor (2) generates a measured signal as a function of a property of the compressed air fed through the measured air line. A humidifier (8) humidifies the compressed air upstream of the sensor. An output unit (12) outputs information about the property of the compressed air to a user on the basis of the measured signal. A tap (4) removes compressed air and an actuator (5) changes a volume flow and/or mass flow of the compressed air, which volume flow and/or mass flow prevails in the measured air line. The actuator is inserted into the tap in a measuring mode and is removed from the tap in a compressed air removal mode.

Abstract: A method for operating an air-drying device (10) and an air-drying device (10) are provided. The air-drying device (10) has at least one adsorption device (20) with a first adsorption section (21), a second adsorption section (22), an air feed line (11), an air removal line and an analysis unit (13). The first adsorption section (21) and the second adsorption section (22) can be used alternatingly to dry air (70). The air feed line (11) feeds air (70) to be dried and is connected to an inlet opening (24) of the adsorption device (20) in a fluid-communicating manner. The air removal line (12) removes dried air (70) and is connected to an outlet opening (25) of the adsorption device (20) in a fluid-communicating manner. A compressed air system (60) for providing compressed air (70) has such an air-drying device (10).
