Centrifugal Fans
Centrifugal fans (also known as centrifugal extractor fans) are used in both domestic and industrial applications. They are widely used for ventilation and air conditioning in buildings to industrial processes that require the movement of large volumes of air.
Our fantastic range includes centrifugal fans from leading brands including Domus Ventilation and are available in a variety of extraction rates to suit your needs.

FAQs
How does a centrifugal fan work?
A centrifugal fan is designed to create a continuous airflow by using centrifugal force to move the air outwards.
When the fan is turned on, the rotating impeller creates a low-pressure area at the centre, and air is drawn into the fan through the inlet. The air is then accelerated by centrifugal force and pushed outwards towards the outlet of the fan. The speed of the fan blades and the shape of the housing determine the amount of air that the fan can move.
What are the key components of a centrifugal fan?
The centrifugal fan consists of a housing, an impeller and a motor, which work together to create the airflow.
The impeller is the main component of the fan and is made up of a series of forward curved or backward curved blades arranged in a circular pattern which rotate at high speed, allowing it to draw in air from the centre and propel it outwards. The housing refers to the casing containing the impeller and is designed to direct the airflow through the fan. The shape and size of the housing determine the fan's performance characteristics. The fan also has an inlet where air enters and an outlet where the airflow is discharged. These openings are designed to optimize airflow efficiency.
What are the benefits of centrifugal extractor fans?
Air extraction and improved air quality
Centrifugal fans are popular thanks to their ability to extract air and maintain good indoor air quality. They are designed to promote a healthier living environment by removing stale air, odours and moisture from areas such as kitchens or bathrooms. They also help to prevent mould by removing excess humidity from the air and preventing the build-up of condensation.
Reduced noise levels
Centrifugal extractor fans are designed to operate quietly. The blades and housing design help to reduce air turbulence and minimise noise levels during operation for a peaceful and comfortable environment.
Versatile installation
Centrifugal fans can be mounted on walls and ceilings or directly in line with the ducting system. Some centrifugal extractor fans come with adjustable speed settings, giving you control over the extraction rate and allowing you to customise the ventilation for different spaces.
Are centrifugal fans energy-efficient fans?
Centrifugal fans can be moderately energy-efficient if they are installed correctly, as well as maintained and cleaned regularly. This allows the fan to operate as effectively as possible, helping to lower energy consumption and energy bills.
What is the difference between a centrifugal fan and an axial fan?
A centrifugal fan works by generating pressure through an impeller which then propels air outward in a continuous air stream, whereas axial fans move air in a linear direction, making them better suited for larger spaces that require a continuous flow of air, such as warehouses or factories.
