Abstract
A fan-supported gas mask and breathing equipment with a fan unit with adjustable delivery output such that the delivery output of the fan and detection sensor will be automatically adjusted to the necessary filter property, depending on the type of the filter insert used. To achieve this, the filter connection (10) and the filter insert (16) are provided with a marking, which characterizes the filter property (particle filter or gas filter), on the one hand, and, on the other hand, actuates electric contacts for setting the necessary fan output and, if desired, for actuating a detection sensor.
