Powered Air Purifying Respiratory System

Powered filtering respiratory system (1) with - a filter element (3) which is designed to a cleaning of ambient air (33) and provided, - a blower unit (30) which is configured at an inlet side (31) to a suction of the ambient air (33) through the filter element (3) and to generate a respiratory airflow (37) at an outlet (35) and provided, Is connected to one face part (7), which is designed as a breathing mask, as a sighting mask or as a breathing hood to a supply of breathing air flow (37) to a user (100) and with an air supply line (9) which leads to a - is formed supply of breathing air flow (37) from the outlet (35) of the blower unit (30) to a user (100) and provided - one at the outlet side (35) of the blower unit (30) arranged pressure sensor (8), which leads to a metrological detection of a difference in pressure of the respiratory air volume (37) at the outlet side (35) of the blower unit (30) relative to the ambient air (33) as a is formed actual pressure value (81) and provided, - a control unit (5) which is formed to an operation of the blower unit (30) to a control of the respiratory air volume (37) and provided, characterized, in that - the face part (7) with the tube element (9) forms a face piece / tube combination (79), - a data memory (53) in or on the control unit (5) is provided which is adapted and intended to specific characteristics (790) to provide the face piece / tube combination (79) and operational characteristics (530) of the blower unit (30), - is formed, the control unit (5) and adapted from the operational characteristics (530) of the blower unit (30) and the specific characteristics of the face piece / tube combination (79) a target pressure value (83) for the current operation of the fan filter respiratory system (1 ) identify with the face piece / hose combination (79) - is formed, the control unit (5) and intended to detect the actual pressure value (81) of the pressure sensor (8) and to compare with the target pressure value (83) and generate a specific error signal (1000) and to provide, if the current measured pressure value (81) falls below this set pressure value (83).
