Axial Fan Blade Types

The oscillator is a mechanism that motions the fan.

Axial fan blade types. 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. How does an axial fan work. The wing of an aircraft has an aerofoil shape which as it is propelled forwards the air is diverted above and below the wing.

Examples of axial fans are. The compromise is the air throw i e. Typically the types of fans discussed in this manual can handle resistances up to approximately 1 in. The different blades can be characterized as shown in the capacity diagram below.

As well as the curvature of the whole blade fig 1. Neither is a bad choice but there are situations when one should be selected over the other. The flow is axial at entry and exit. 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.

An axial fan blade works on the same principle as how an aircraft wing generates lift. For axial fans the propeller principle is employed. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. 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 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. The construction is often build to be installed in a wall or located individually in the room. Types of blades used in centrifugal fans are. Straight steel plate paddle wheel.

This type of fan is a combination of radia and axial flow. 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. So what type of fan axial or radial is better for your application. Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans.

Vane axial fans are variations of the tube axial fans with air straightening vanes added in front of or behind the propeller blades. Hence choosing the right type of fan often comes down to factors such as air displacement volume and even blade type. Axial vs centrifugal fans. Axial fans can have widely varied operating characteristics depending on blade width and shape number of blades and tip speed.

Special types of fans are used as low pressure compressor stages in aircraft engines. 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.
