| Summary: | A respirator has a filter that is located in an air duct. A blower has an air conduction housing and an impeller wheel located in said air conduction housing, with an impeller wheel that is rotationally mounted inside said housing. The blower is controlled by a sensor. The output of the blower is controlled by means of an electronic control circuit. The sensor is a volume flow or mass flow sensor located in the air duct, and is independent of the blower and controls the blower by means of the control circuit so that the flow of respiratory air remains essentially constant. |
