Abstract
A blower filter device includes a blower unit that draws and delivers ambient air; a filter unit that filters a harmful substance, or a filter coupling to couple and uncouple the filter unit. A control unit is configured to actuate the blower unit, to determine an operating state of the blower filter device and/or other respirator system components and/or a respirator system (100) as a whole and to generate an alarm if a determined operating state indicates a disturbance. An output unit is configured to receive the alarm from the control unit and to output the alarm. A communication interface (228) is configured for wireless network integration and to transmit the alarm via the network (238). A respirator system (100) with such a blower filter device, an operational infrastructure (300) with such a respirator system, as well as a method of blower filter operation and operational infrastructure monitoring are provided.
