Areas of application for built-in fans

Whether in the kitchen of a catering trade, in offices or in the bathroom of a family household, there are versatile uses for wall fans. These fans are particularly practical in rooms where there are no windows. A good example of this is a bathroom or a toilet, in some of which no or only a small window is integrated. This means that there is fresh air even in rooms without windows. In-wall fans are often used in industry or in catering areas. For example, in a laboratory or in smoking rooms, where the fresh air supply is important for a pleasant working atmosphere. Corrosion-resistant materials are important in swimming pools or kitchens, so that trouble-free operation can be ensured even in contact with moisture. Wall fans are also often found in public toilets. Offices, medical practices, cinemas, gyms, gyms or hospitals, there are numerous possible uses for these fans.

Power of 230 volt wall fans

The output of 230 volt wall fans ranges between 20 and 180 watts. Models with 20 watts are suitable for rooms where no large air exchange is required. For example in a guest toilet or in living rooms. Powerful versions such as the CasaFan EQ 35/4 M with 150 watts or EQ 40/4 M with 180 watts can also cope with larger requirements. These fans also ensure good air exchange in boardrooms, changing rooms, gyms or school rooms.

Calculate air performance and hourly air exchange

The maximum air output shows which wall-mounted fan model is the right one for the intended use. This is specified by the manufacturer in m³. The wattage is only meaningful to a limited extent, since a model with a lower wattage can have a higher maximum air output. Nevertheless, it can generally be said that a wall fan with 40 watts has a lower maximum air output than a model with more than 100 watts. Which air output is required depends on the size of the room and its purpose. For the calculation, the room size is multiplied by the air exchange rate. There are predefined values for the air exchange rate, which are based on experience. Some of these values can be found in the form of tables on certain websites. For example, an air exchange rate of 6 to 8 is recommended for restaurants. Which value is ultimately used for the calculation of the hourly air exchange depends on the personal assessment. Basically, it is better to take a higher value.

Example: For a restaurant with 120 m³ and an air exchange rate of 8, a wall fan model with a maximum air output of 960 m³ is recommended. Using this example, a CasaFan EQ 20/4 M would be insufficient. A suitable choice would be with the CasaFan EQ 20/2 M or EQ 25/4 M.

Security and Design

Wall fans such as those from CasaFan are attractive design solutions. Powder-coated in black, these fans can be integrated into any living, business and work area. Sometimes there are wall fans without a cover, which contributes to a fashionable look. CasaFan built-in fans also meet the safety requirements. Accordingly, there is a cover so that no fingers or objects get into the fans. Another security feature is the protection class according to IP54.


How loud a built-in fan is, is only of limited importance. This is very dependent on the area of application. In an auditorium, a cinema or a commercial kitchen, the audience is not aware of a higher volume. It is different in a waiting room or a toilet. In a classroom, a loud fan can disrupt student concentration. So when buying, it is advisable to pay attention to the decibel number of the respective model.

Overview of functions

Time control is also practical and energy-saving. A reversible fan model is also advantageous. Reversible means that the fan can be used as an extract air fan or supply air fan. If fresh air is to enter a room from outside, the direction of rotation of the fans is set so that air is drawn in. For example, to discharge the stuffy air of a room to the outside, the direction of rotation of the fans is reversed. Except for the CasaFan models EQ 20 / 4M and EQ 25 / 4M, this is possible with all CasaFan wall built-in fans. Ideally, the speed of a wall fan can also be regulated by means of a controller or transformer. This allows the air exchange to be adapted to individual needs. For example, in the event of a higher number of visitors in the cinema at the weekend or in salesrooms.

If there is a lot of activity in a smoking room or in a gastro kitchen, the flaps are opened and the smoke is discharged to the outside by the fans. The same is also possible with increased humidity or elevated temperatures. Other accessories are available with a speed controller.
