Axial flow fans are available in a large number of sizes and In addition to the standard type, built-in alarm types are also voltage characteristics, from large air flow AC axial flow fans to available which detect and signal fan rotation abnormalities. Stall will occur in a small window of operating conditions and can be identified with a sudden major increase in noise and vibration levels with an immediate reduction in performance. The axial flow fan is well known around the average household as a ceiling fan: the motor spins blades around a hub, which moves air parallel to the axis of rotation. In the broader sense, the air passes through the impeller. 9 53 It is shown in Figure 4 (a) that the centrifugal fan has a higher pressure head at no flow than the axial fan, but the axial has a higher maximum. The air velocity is increased through rotational force, which produces velocity pressure (kinetic energy) and a small amount of static pressure (potential. , , Sound. The mixed flow fan is a development of the axial fan and, as shown in Figure 8, has a conical shaped impeller where air is drawn radially through the expanding channels and then passed axially through the straightening guide vanes.
