Using the fan at its peak efficiency minimises the power consumption and noise emitted from the fan whilst delivering the required performance. The double-discharge volute casing is a structural constraint and is maintained for its shape. The centrifugal fans with backward-curved blades are designed as freewheel fans and do not require a scroll housing. How a Centrifugal Fan Works . The fan static pressure per stage is limited, typically to a maximum of about 600 Pa at the design point, while the fan dynamic pressure is about 70% of the total pressure. For a given flow rate an axial flow fan is considerably more compact than the corresponding centrifugal fan, and fits very conveniently into a duct of circular cross-section. These fans can surge or pulsate when their air volumes are reduced to the point where they operate to the left of their pressure peaks. The centrifugal fans with backward-curved blades are designed as freewheel fans and do not require a scroll housing. The centrifugal fan was invented in 1556 to ventilate mines.
