Axial Fan Blade Types

Vane axial fans are variations of the tube axial fans with air straightening vanes added in front of or behind the propeller blades.

Axial fan blade types.

For axial fans the propeller principle is employed. As well as the curvature of the whole blade fig 1. Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans. 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.

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 compromise is the air throw i e. 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. The construction is often build to be installed in a wall or located individually in the room.

In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. Hence choosing the right type of fan often comes down to factors such as air displacement volume and even blade type. Straight steel plate paddle wheel. So what type of fan axial or radial is better for your application.

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. A propeller axial fan consists of a a propeller shaped blade and a drive motor mounted on a flat frame. Special types of fans are used as low pressure compressor stages in aircraft engines.

Axial vs centrifugal fans. The different blades can be characterized as shown in the capacity diagram below. The airflow through the blower wheel with the propeller blades is conducted to a great extent parallel to the axis of rotation hence the name axial fans. Axial fans can have widely varied operating characteristics depending on blade width and shape number of blades and tip speed.

Examples of axial fans are. Determine what multi wing axial fan blades could be the right fit for you based on the type of axial fan blades you need or want browse axial fans by blade type. Typically the types of fans discussed in this manual can handle resistances up to approximately 1 in. The oscillator is a mechanism that motions the fan.

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. Neither is a bad choice but there are situations when one should be selected over the other. Types of blades used in centrifugal fans are.

The flow is axial at entry and exit. How does an axial fan work.
