| description | A radial fan assembly for use in a powered air purifying respirator includes at least an impeller, a printed circuit board and a scroll casing. The scroll casing has a first and a second scroll casing element. The second scroll casing element includes at least a portion of the printed circuit board. When the radial fan assembly is used in a powered air purifying respirators, the respirator may also include components such as a filter assembly.
L'invention concerne un ensemble ventilateur radial s'utilisant dans un respirateur électrique à purification d'air, qui comprend au moins une hélice, une carte de circuit imprimé et une enveloppe spirale. L'enveloppe spirale comporte un premier et un second élément d'enveloppe spirale. Le second élément d'enveloppe spirale comprend au moins une partie de la carte de circuit imprimé. Quand l'ensemble ventilateur radial est utilisé dans des respirateurs électriques à purification d'air, le respirateur peut aussi comprendre des composants tels qu'un ensemble filtre. |
