Abstract

Die Atemschutzvorrichtung weist in einem Luftkanal einen Filter (6) auf. Ein Gebläse (5) besitzt ein Luftführungsgehäuse (18) und ein in diesem drehbar gelagertes Flügelrad (19). Das Gebläse (5) ist von einem Sensor (3) gesteuert. Mittels einer elektronischen Steuerschaltung (7) wird die Leistung des Gebläses (5) gesteuert. Der Sensor (3) ist ein im Luftkanal angeordneter Volumen- oder Massenstrom-Sensor, der unabhängig vom Gebläse (5) ist und der über die Steuerschaltung (7) das Gebläse (5) so steuert, dass der Atemluftstrom im wesentlichen konstant bleibt.

Figure 00000001
The respiratory protection device has a filter (6) in an air duct. A blower (5) has an air guide housing (18) and an impeller (19) rotatably mounted therein. The fan (5) is controlled by a sensor (3). The power of the blower (5) is controlled by means of an electronic control circuit (7). The sensor (3) is a volume or mass flow sensor arranged in the air duct, which is independent of the blower (5) and which controls the blower (5) via the control circuit (7) so that the breathing air flow remains essentially constant.
