What is Tangential Fan, Place of Use and Selection

In our article where we will give information about what is a tangential fan, where it is used, how to choose it, we give detailed information about the subject. Continue reading.

It is a type of fan that provides air flow on a circular trajectory. Tangential fans have the advantages of low noise level, high efficiency and long life.

It is generally used in heating, cooling, ventilation and air conditioning systems. For example, radiators, fireplaces, air conditioning units, furnaces and refrigerators are commonly used devices.

Where Does the Name Tangential Fan Come From?

The name tangential fan comes from the operating principle of this type of fan. They are also known as horizontal throw radial fans. These fans consist of blades rotating inside a cylindrical rotor.

The blades create an air flow in a direction perpendicular to the axis of the rotor. This air flow is tangential to the surface of the rotor and is therefore called tangential.

They provide high airflow in low back pressure applications. They are used in areas such as heaters, electronic cooling, overhead projectors, solariums, ventilation, industrial kitchen and commercial cooling

Tangential Fan Features

They are fansconsisting of a long cylindrical impeller with a structure similar to a forward inclined propeller. These fans provide an airflow that provides a wide curtain of air at a constant speed across the width of the air outlet. Some of their features are:

• It does not rust with its body made of high quality galvanized steel sheet .
• It is one of the silent fan types with low noise level, light weight and high flow rate.
• There are models that can operate as AC or DC.
• It is produced in different fan diameters (30 mm, 40 mm, 80 mm, 680 mm) and different fan lengths (180 mm, 240 mm, 300 mm, 360 mm, 400 mm, 480 mm, 500 mm, 600 mm, 720 mm, 800 mm).
• The air flow capacity ranges from 50 m3/h to 385 m3/h.
• They also vary in efficiency and are available in energy-efficient models.

There are some factors to be considered when selecting a tangential fan. These are:

• Air flow: The air flow rate and pressure to be provided by the fan must be suitable for the needs.
• Size: The sizeshould be suitable forthe areawhere the fan will be installed.
• Power: The electrical power and consumption required for fan operation must be taken into account.
• Noise: The noise level of the fan when it is running should be at a level that does not cause discomfort.
• Material: The material used in the construction of the fan must be of good quality, durable and resistant to corrosion.

These fans are used to provide a wide and uniform air flow in front of the heater/cooler coils.

General application areas are floor convectors, air curtains and panel cooling systems. Tangential fans can be supplied in different fan diameters and different lengths.

Tangential Fan Types

For example, Aircol’s AKS series tangential fans are available in different fan diameters (30 mm, 40 mm, 80 mm, 680 mm) and different fan lengths (180 mm, 240 mm, 300 mm, 360 mm, 400 mm, 480 mm, 500 mm, 600 mm, 720 mm, 800 mm).

The air flow capacity of these fans varies between 50 m3/h and 385 m3/h. They are also divided into AC or DC fans.

Advantages of Tangential Fan

Reasons to buy a tangential radial fan can be the following:

• A tangential radial fan provides a more homogeneous airflow than a radial fan. This is especially important to achieve an even temperature distribution in heating or cooling systems such as furnaces.
• The tangential radial fan runs quieter than the radial fan , which can be preferred to reduce noise pollution and create a more comfortable environment.
• The tangential radial fan has a more compact designthan the radial fan, which is advantageous for saving space and giving an aesthetic appearance.

If you want to buy a tangential radial fan, you can research various options to choose a model that suits you.

Which is the Best Tangential Fan?

It would not be right to say the best model in terms of their use. In the preference and selection phase, it is necessary to act depending on the area of use.

There are many criteria to be considered such as technical specifications and size. The best tangential fan is preferred when purchased by paying attention to these during the selection phase. Ensure quality use by choosing the most suitable one.

The appropriate fan size should be determined according to the internal height of the convector. Tangential fan prices can vary according to brand, model, capacity and efficiency. Kampa website has different brands and models of tangential fan types and prices.
