Description

technical field [0001] The invention relates to a blower filter device for a blower filter system, which has at least one filter, a fan wheel arranged in a fan housing, a motor for driving the fan wheel and a motor for actuating the fan wheel. Engine and control unit for processing device-specific parameters of the blower filter device. Furthermore, the invention relates to a blower filter system having a blower filter device, a head piece and a connecting hose, which connects the blower filter device and the head piece to one another in a fluid communication manner. Background technique [0002] The blower filter system is used for light and medium-sized protective masks and supports the wearer of the filter of the protective mask in that the blower filter system reduces the breathing resistance in contrast to conventional gas masks and thus enables long-term resistance. Fatigue applications are possible. A blower filter system consists of the following main components: a...
