Problems solved by technology
However, depending on the conditions of use, the user is often unable to perceive a visual signal when worn on the back or hear an audio signal in a rather noisy situation due to environmental conditions
Under unfavorable conditions, even in working use where several people work in groups, it may happen that people located nearby will not be able to detect the alarm from the blower filter unit; mutual assistance is often difficult in such conditions

A blower filter device for a respiratory protection system (100) is disclosed, wherein the blower filter device has: a blower unit which is designed to suck in and feed in ambient air; a filter unit which is designed to filter at least one pollutant from the sucked-in or fed-in ambient air, or a filter-coupling device for coupling or decoupling such a filter unit; a control unit which is designed to actuate the blower unit, to determine an operating state of the blower filter device and / or of other components of the respiratory protection system (100) or of the respiratory protection system (100) in its entirety, and to generate an alarm if the determined operating state indicates a fault; and an output unit which is designed to receive the alarm from the control unit and output said alarm. According to the invention, a communication interface (228) is also provided which is designed to be integrated in a wireless fashion into a network (238) and to transmit the alarm to other subscribers to the network (238). In addition, the following are disclosed: a respiratory protection system (100) having a blower filter device according to the invention, operational infrastructure (300) with at least one respiratory protection system (100) according to the invention, and a method for operating a blower filter device and for monitoring operational infrastructure (300).
Description
technical field [0001] The present invention relates to a blower filter device, a respiratory protection system, a usage infrastructure, and a method for driving a blower filter device and monitoring a usage infrastructure. Background technique [0002] Respiratory protection systems with blower filters are used for light and moderate respiratory protection and support users of respiratory protection filters in that they reduce the breathing resistance different from traditional respirators and thus make fatigue-free long-term Use of respiratory protection is possible. [0003] Common respiratory protection systems have blower filters worn on the harness and headgear in the form of a hood or mask. The blower filter device and the headgear are connected by a hose. Ambient air (possibly polluted) is drawn through the filter by means of a blower filter, whereupon the ambient air is freed of harmful substances, and then sent via a hose to the headgear for supply to the wearer ...
