Abstract

See full text

A blower filter respirator system (1) has a filter element (3) for filtering ambient air (33), a blower unit (30) and a face part (7) with a tube element (9)—face part/tube combination (79)—for feeding an amount of breathing air (37) to a user (100). A pressure sensor (8) is on an outlet side (35) of the blower unit (30) measuring breathing air pressure values (81) by detecting a pressure difference on the outlet side (35) of the blower unit (30) against the ambient air (33). A control unit (5) is configured to operate the blower unit (30) and control breathing air (37) and is configured to determine a desired pressure value (83) for current operation with the face part/tube combination (79) from operation-related properties (530) of the blower unit (30) and specific properties of the face part/tube combination (79) and for comparing with the current pressure value (81).
