Axial flow fan diagram.

Axial flow fans have developed rapidly since the second world war due to the creation of a range of high strength aluminium alloys. The shape of your blades and the direction they travel will define the performance characteristics of your fan. The different blades can be characterized as shown in the capacity diagram below. Mixed flow fans develops higher pressures than axial fans.

The inlet and outlet velocities of the air through the blades will be the same for axial fans and different for centrifugal fans v ᵢ and v ₒ. An axial fan is a type of fan that causes gas to flow through it in an axial direction parallel to the shaft about which the blades rotate. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. Conversion 460 230 volt 30.

The axial flow compressors can be of impulse type or reaction type. Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers. The fan is designed to produce a pressure difference and hence force to cause a flow through the fan factors which determine the performance of the fan include the number and shape of the blades. The flow is axial at entry and exit.

Axial fans adhere closely to classical theory and require less know how than centrifugal fans. Wiring schematic for 575 volt three phase axial fan 28 figure 22. The blade profile and variation of pressure and velocity in the stage are shown in the fig. Wiring diagram 23 28 af12 751 23 af18 11 24 single phase 230 volt 25.

Fig 3 shows the velocity diagram for the air flowing into the fan inlet and out of it outlet.
