Abstract: A system includes a blower filter system (20), having a blower filter device (1), a head piece (21) and a flexible connection hose (22), connecting the blower filter device (1) and the head piece to one another in a fluid-communicating manner. A computer (30) is separated in space from the blower filter system. The computer has a communication interface (31), which is designed to transmit data from the computer to the control unit (6) of the blower filter device and/or to receive data from the control unit of the blower filter device to the computer. The blower filter device has at least one communication interface (7) for transmitting data from the control unit to an external computer and/or for receiving data sent from an external computer to the control unit. A process is provided for checking and setting device-specific parameters of the blower filter device of the blower filter system.

Abstract: A support system (1) for a fan filter device (20) of a fan filter system (30) has a base strap (2) for arranging the support system on the body (40) of a user and has a securing system (3) on the base strap for securing the fan filter device in a first position (4) and in at least one different second position (5) on the base strap. The securing system has a guide element (6), secured to the base strap, to retain the fan filter device in the different positions (4, 5). The securing system has a counter-guide element (10), movably guided on the guide element via at least one guide gap (11), that has at least one securing element (12) for securing the counter-guide element on the fan filter device. A fan filter device for a fan filter system and a fan filter system are also provided.

Abstract: A blower filter device (1) is provided for a blower filter system (20). The blower filter device (1) has at least one filter (2), a fan wheel (4) arranged in a fan housing (3), a motor (5) for driving the fan wheel (3) as well as a control unit (6) for actuating motor (5) and for processing device-specific parameters of the blower filter device (1). The blower filter device (1) has a housing (13) with a mounting slot (14) for a communication interface module (7). The contact point (15) is arranged in mounting slot (14) for the data-communicating connection of communication interface module (7) to the control unit (6). The blower filter system (20) includes such a blower filter device (1) and, a head piece (21) and a flexible connection hose (22) providing a fluid-communicating connection between the blower filter device (1) and the head piece (21).
