Beschreibung
Zusammenfassung:	A blower filter device (3) is connectable to a voltage supply unit (2) and includes a blower unit (5), a filter mount (14), an internal energy storage unit (7), an energy interface (9), a current limitation device (13), a sensor array (16, 17, 18) and a control device (6). The current limitation device is activated upon disconnecting the energy interface from the voltage supply unit. The activated current limitation device limits the intensity of a current from the energy interface to the internal energy storage device. Upon the voltage supply unit being connected to the energy storage device and a predefined deactivating event is detected, the control device deactivates the current limitation device. The deactivating event is based on a charging voltage of the internal energy storage unit and/or on a time period that has elapsed since the connection. A process is provided for operating such a blower filter device.
