Abstract
A gas mask and breathing equipment with a respirator, to the respiration gas inlet of which a respiration gas filter and a respiration supporting blower unit are connected, is formed such that the components controlling the power output are arranged in areas that are favorable for operation and are able to control the blower unit in the case of a filter change or during changes in the state of loading of the built-in filters during operation such that they can be adapted to the changing performance characteristics. The housing of the blower unit (2) has a saddle-shaped upper part (5), over which a control unit (7), designed as an independent housing module, can be attached in a bow-like manner, and establishes the electrical and pneumatic connections to the blower unit.
