Ventilation system's layout for an air-supply device has a fan blade to rotate in bearings on a swivel pin as well as an air inlet and a curved guide wall to control radial air flow

摘要

Rotating in bearings on a swivel pin (12), a fan blade (14) is allocated an air inlet (18) on one side (16). Air is supplied in an axial direction (A) at the air inlet and delivered further in a radial direction as a radial flow. Fitted partly on the periphery towards the fan blade, there is a curved guide wall (20), on which the radial flow occurs to be guided along it.
