What is a tangential fan?

Tangential fans are fans that are used in a variety of applications where uniform air distribution over a wide area is required. They are characterised by their elongated shape and the way in which the air is moved through the fan.

When selecting a tangential fan, it is important to consider the specific requirements of the application. This includes

the required air volume, the available space, the noise development and energy consumption.

Variable speed models offer a high degree of flexibility to adapt the air supply to different conditions, while low-noise models are suitable for applications where minimising noise pollution is important.

Tangential fans are therefore a versatile and efficient solution for the even distribution of air over wide areas. Their compact design and ability to be used in a wide variety of applications make them an indispensable element in modern ventilation and cooling systems, underfloor convectors and door air curtains.

How does a tangential fan work?

Tangential fans work according to the principle of cross-flow conveying, in which the air is drawn in parallel to the axis of rotation of the fan and then blown out at right angles to the axis of rotation. This mode of operation differs fundamentally from axial fans or centrifugal fans and enables very even air distribution over the entire length of the fan.

Structure and components

The centrepiece of a tangential fan is a cylindrical rotor with numerous blades arranged lengthwise. These vanes are designed so that when they rotate, they efficiently suck in the air and push it along the length of the cylinder. The motor that drives the rotor is often positioned in the centre of the cylinder to ensure optimum balance and efficiency.

Functional principle

The functional principle is based on the generation of an air flow along the rotor axis. The rotary movement of the rotor guides air along the louvres and pushes it outwards by centrifugal force. This process results in a continuous air flow across the axis of rotation of the rotor. The special design of the fan allows air to be distributed over a large area, resulting in more effective and even ventilation.

How are tangential fans constructed?

The design of tangential fans is decisive for their functionality and efficiency. This special type of fan is designed to generate a wide and even air flow, making it indispensable for a wide range of ventilation and air conditioning applications. To understand the design of tangential fans, it is important to look at their main components and how these parts interact.

Main components of a tangential fan

The basic components of a tangential fan include

the roller (rotor + vanes/blades) the enclosure and the motor.

Each of these parts plays a crucial role in the performance and functionality of the fan.

The rotor

The rotor forms the centrepiece of the tangential fan. It is cylindrical in shape and equipped with a series of louvres that are arranged lengthwise along its entire length. The rotor with the blades (vanes) is also called a roller. This design enables the rotor to effectively draw in air and move it along the cylinder.

The slats

The louvres or blades are decisive for the air movement. They are designed in such a way that they draw in air as the rotor rotates and guide it through the fan. Their specific shape and arrangement are crucial for the efficiency of the air flow.

The enclosure

The housing of a tangential fan encloses the rotor and the blades and serves several purposes. It not only contributes to safety by covering moving parts, but also optimises the air flow. The shape and internal structure of the casing are designed to smooth and direct the airflow to maximise efficiency.

The motor

The motor is responsible for driving the rotor. Tangential fans often use a compact, powerful motor that is mounted directly on the rotor to ensure efficient transmission of the drive power. The positioning and performance of the motor are crucial to the overall performance of the fan.

How are tangential fans installed?

The installation of tangential fans is a critical step to ensure their efficiency and performance in various applications. This process requires careful planning and execution to ensure optimum air distribution and noise minimisation. The basic steps and considerations for the installation of tangential fans are described in detail below.

Preparation and planning

Thorough preparation and planning is required before a tangential fan is installed. This includes determining the optimum location for the fan, assessing the required air performance and selecting the appropriate fan model. It is equally important to consider the space available to ensure that the fan can operate effectively without being restricted by neighbouring structures.

Assembly and installation

The planning phase is followed by the assembly and installation of the tangential fan. This usually comprises the following steps:

Mounting the enclosure: The fan enclosure must be securely mounted in the intended location to ensure a stable and durable installation. It is important to follow the manufacturer's instructions exactly and to use suitable fixing materials. Inserting the fan: Once the housing has been installed, the tangential fan is carefully inserted into its position. Ensure that the fan is correctly aligned to optimise the air flow. Electrical connections: The electrical connections must be made in accordance with the safety regulations and the manufacturer's instructions. Proper cabling is crucial to ensure the functionality and safety of the fan.

Inspection and commissioning

After installing the tangential fan, a thorough check is necessary. It should be ensured that the fan has been installed correctly, is running free of obstacles and that the electrical connections are secure. The fan can then be put into operation, whereby an initial performance and noise test is recommended to ensure that the fan works as expected.

What are the advantages of tangential fans?

Tangential fans offer a number of advantages that make them particularly valuable for a variety of applications in ventilation, air conditioning and heating technology. The advantages result from their unique design and functional principle, which enables efficient and even air distribution.

Even air distribution

An outstanding feature of tangential fans is their ability to generate a wide and even air flow. Due to the special arrangement of the blades and the way the air is channelled through the fan, tangential fans can distribute air over a large area. This is particularly advantageous in applications where uniform air circulation is required, such as in air conditioning systems, ventilation systems, underfloor convectors or door air curtains.

Compact design

Tangential fans are characterised by their compact and flat design. This enables flexible integration into a wide range of devices and systems where space restrictions play a role. Their design makes them ideal for use in narrow spaces, such as in wall or ceiling installations.

Low-noise operation

The design of tangential fans enables comparatively quiet operation. This is particularly advantageous in environments where noise is a critical criterion, such as in living rooms, offices or near workplaces. The noise reduction is achieved by the arrangement of the louvres and the gentle intake and discharge of the air.

High efficiency

Tangential fans offer high efficiency in air movement. Thanks to their special mode of operation, they can generate a large air volume flow with low energy consumption. This makes them an energy-efficient choice for many ventilation and cooling systems, underfloor convectors and door air curtains.

Versatile application options

Thanks to their unique properties, tangential fans can be used in a wide range of applications. They are used in air conditioning systems, heat pumps, heaters, electronic cooling systems and many other areas where efficient, even and quiet air distribution is required.

What tangential fans are available?

Tangential fans vary in design, size and performance to cover a wide range of applications in ventilation, air conditioning and heating technology. The diversity of these fans makes it possible to find a suitable solution for every specific requirement. The different types of tangential fans and their characteristic features are presented below to help you choose the right model.

Standard tangential fans

This classic version is the most widely used form of tangential fan. They are characterised by a simple, robust design and offer reliable performance for a wide range of standard applications, such as in air conditioning units or ventilation systems for residential and office buildings.

Tangential fans with EC motor

Tangential fans with electronically commutated (EC) motors stand for high energy efficiency and improved speed controllability. These models are particularly suitable for applications where low energy consumption and precise control of the air flow are required. They are often used in energy-efficient air conditioning and ventilation systems and in applications that require flexible air flow control.

Compact tangential fans

Compact tangential fans are specially designed for use in confined spaces. Their small size makes them ideal for installation in narrow devices such as slotted ventilation systems, auxiliary heaters or cooling units in the electronics industry. Despite their compact design, these fans deliver impressive performance for their size.

High-performance tangential fans

For applications that require a high air flow rate, high-performance tangential fans provide the necessary capacity. These models are designed to ensure efficient air movement even at high operating loads. Areas of application include industrial ventilation systems, large air conditioning systems and other areas where maximum air circulation is required.

What is the difference between a cross-flow fan, a cross-flow fan and a cross-flow blower?

Although the terms cross-flow fan, cross-flow ventilator and cross-flow blower are often used interchangeably, the differences in the terms refer to size, performance and intended use. From small fans for electronics cooling to large blowers for industrial systems, each of these devices offers specific advantages for its application. When making a selection, it is therefore important to consider the specific requirements of the application in order to find the optimum solution for air movement and cooling.

Tangential fan

The term " tangential fan" generally refers to a device that draws in air parallel to the axis of rotation and blows it out sideways. This definition is very similar to that of the tangential fan. However, it refers more to smaller devices such as those used in electronic applications, e.g. in computers, projectors or compact air conditioning units. The term "fan" is often used for devices that primarily serve to cool or gently circulate air in a confined space.

Tangential fan

" Tangential fan" is a broader term that describes devices that move air perpendicular to the axis of rotation of the fan wheel. This category can include both smaller fans and larger blowers and is often used in a wider context, including ventilation, air conditioning and heating systems. The focus here is on the efficiency of air movement and distribution over a larger area or space.

Tangential blower

The " tangential fan" usually refers to larger and more powerful versions of tangential fans that are capable of generating a high air flow rate. These are typically used in industrial applications, large air conditioning and ventilation systems or in situations where a significant amount of air needs to be moved over long distances or through complex systems. The term "blower" often implies more powerful performance and is aimed at more demanding or larger applications.
