Axial Fan Blade Types

In a mixed flow fan the air flows in both axial and radial direction relative to the shaft.

Axial fan blade types.

Examples of axial fans are. Vane axial fans are variations of the tube axial fans with air straightening vanes added in front of or behind the propeller blades. A propeller axial fan consists of a a propeller shaped blade and a drive motor mounted on a flat frame. 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 different blades can be characterized as shown in the capacity diagram below. For axial fans the propeller principle is employed. The compromise is the air throw i e. The construction is often build to be installed in a wall or located individually in the room.

Axial vs centrifugal fans. The wing of an aircraft has an aerofoil shape which as it is propelled forwards the air is diverted above and below the wing. The rotating blades have a complex shape in order to achieve a good efficiency factor. Types of blades used in centrifugal fans are.

The flow is axial at entry and exit. Typically the types of fans discussed in this manual can handle resistances up to approximately 1 in. Straight steel plate paddle wheel. The most common type of fan for air cooled heat exchanger ache is less than.

There are two primary varieties of fan axial fans and centrifugal fans. Hence choosing the right type of fan often comes down to factors such as air displacement volume and even blade type. The oscillator is a mechanism that motions the fan. Neither is a bad choice but there are situations when one should be selected over the other.

Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans. How does an axial fan work. Special types of fans are used as low pressure compressor stages in aircraft engines. 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.

So what type of fan axial or radial is better for your application. As well as the curvature of the whole blade fig 1. An axial fan blade works on the same principle as how an aircraft wing generates lift. Basic elements of a typical table fan include the fan blade base armature and lead wires motor blade guard motor housing oscillator gearbox and oscillator shaft.

This type of fan is a combination of radia and axial flow. To help clear up that confusion here is a breakdown of the fan types their benefits and their uses.
