Centrifugal fans are also called radial fans and work according to the centrifugal principle. With a radial or centrifugal fan, the air is sucked in axially, bent 90°, and blown out transversely to the longitudinal direction of the axis (radially).
Centrifugal (or radial) fans move relatively smaller amounts of air, but can build up greater pressure. For this reason, they are also used as supply and exhaust ventilation systems in commercial spaces, office buildings and other buildings.
