There are many different types on the market, from the most straightforward and cheapest models to those that combine high performance with a modern and innovative design, integrating perfectly into the decor of your home. Are you debating whether to choose a table-top or a pedestal fan, which is quieter and more elegant? Or maybe you're planning to buy a ceiling fan, the most effective in its class for even ventilation? At Klarstein, you will find a wide range of products designed to meet your specific needs. Please browse our product gallery and find out which one is right for you.
How does a fan work?
Unlike air conditioning, ventilation has a straightforward operation. The airflow generated by a fan in the room sets cold and warm flows in motion, increasing the evaporation rate on the skin, which lowers the body temperature and increases the feeling of coolness.
The greater the volume of air moved, the greater the feeling of freshness. This air volume varies with the size and power of the device. It is important to know that a fan, even a high-powered one, cannot considerably lower the room's temperature as an air conditioner would. In the following table, we compare the main categories, outlining the airflow they can generate.
|Type of fan||Airflow (m3/mn)||Room size (m²)||Where to place it|
|Table fan||15 m3/min||5 m²||On the table|
|Tower fan||100 m3/min||20 m²||Bedroom, living room|
|Ceiling fan||150 m3/min||30 m²||Living room, bedroom, kitchen|
Main types of fans
Each type of fan provides a different airflow, suitable for different environments and situations.
Ceiling fans: they provide the most uniform airflow. It is suitable for large rooms and is often equipped with ceiling light and remote control for maximum ease and comfort. Ceiling fans provide the most pleasant and uniform airflow, caressing and delicate, not direct and therefore not harmful to health. As it expands from the top, the moving air descends downwards in a consistent manner. A ceiling fan is suitable for large rooms but can also be adapted to medium and small rooms when smaller in size. Some models can reverse the airflow to prevent hot and cold air from staying only in certain areas of the ventilated environment and thus allow a healthy change of air.
Tower fans: they do not use a propeller to generate the airflow, as they rely on a wheel that rotates in its casing, and the expelled air may or may not be channelled. Less noisy than pedestal fans, oscillating tower fans consume less energy because the power required for the same air volume delivered is lower. For this reason, they are ideal for a room where silence is essential, as they are whisper quiet: on the other hand, due to their bladeless design, tower fans are not so effective when it is necessary to cool a large room.
Free-standing fans: they are designed for more restrained ventilation. Usually smaller in size, free-standing oscillating fans can only provide cooling to well-defined and limited areas, leveraging their enhanced speed settings and oscillating function. You can easily move them, and you can choose to lock or rotate them to ventilate different areas of the same room. They can ventilate large rooms without the need for electrical and sometimes masonry work, as can be the case with a ceiling model. Obviously, the larger the appliance, the larger the room you can cool with it. Note, however, that floor fans only provide ventilation from the height of the blades, which in the pole type can therefore be adjusted, to have the air at the height you most need.

How to choose the best fan
Choosing a suitable model is not as easy as it might seem. There are many different types. They differ in power, functionality and mode of use, as well as in appearance. So let's try to put things in order and understand the characteristics that a fan should have.
Not all models have blades. Although they are noisy and take up more space, they also make it easier to distribute the air and allow a powerful jet to reach even the hardest to reach corners. The size of the blades depends on the size of the room. The larger the room, the larger the blades should be. This way, you can spread the fresh air evenly throughout the room.
Fan power and consumption
Keep an eye on the capacity, i.e. the maximum power it can reach: the higher its value, the higher its consumption, and, therefore, the higher your energy bill. The most powerful models are ceiling-mounted, but a fan will not consume more than 120 watts in general.
To ensure more air circulation, the blades must be able to turn quickly. Sometimes too much air can be annoying. So make sure you buy a model that offers a choice of speeds.
Ideally, a fan should first of all be quiet. It is annoying to hear a continuous noise, but this does not mean you have to give up the pleasure of fresh air. Models without blades or those with a night function are whisper silent, as the easiest time to hear the noise is at night when all the noise of everyday life dies down. Thanks to the night function, the fan will continue to generate fresh air without making any noise.
A fan must also be safe, especially if there are children in the house or in the environment where you use it. The safest variants are those without blades and a safety cage because there are no visible mechanisms. If you have a device with blades, make sure that the safety grille is made of a very narrow mesh to prevent fingers or hair from getting into it. Also, make sure that your fan stand, if there is one, is solid and not unstable.
Moving air is by definition the purpose of an electric fan, but some models also offer additional functions such as misting, humidification or ionisation. All of these modes modify the air in the room and thus create a greater feeling of freshness. Depending on the mode, an air purification phenomenon is created, thus limiting the risk of asthma.
- Nebulisation: this function allows not only air but also water under pressure to be circulated for a greater cooling effect. Fans with a nebuliser can be portable or fixed, or integrate structures such as parasols.
- Humidification: the humidifying effect allows the humidity of the ambient air to be increased - like a humidifier - so that it is not too dry, which can lead to respiratory problems or asthma.
- Ionisation; ionisation changes the chemistry of the air by loading it with negative ions to stabilise it. For a feeling of well-being, the device must respect the balance between positive ions (cations) and negative ions (anions). In a home or office, this rate is rarely respected and polluting factors include the release of formaldehyde, electromagnetic fields, kitchen vapours, solvents, dust, etc.) which is why anionisation is recommended.
Where to position your fan?
The fan's position depends on the type of device itself and secondly on the room's size and the areas you want to cool. For uniform ventilation of a fairly large room, choose a fairly large ceiling fan and place it in the ceiling's centre with fairly sloping support.
If, on the other hand, you want to ventilate a room without intervening in the electrical system, a large floor fan is ideal: place it near one of the longest walls of the room in the middle of its length and use the fan's adjustability to ventilate the room in all directions.
As for stand fans, which are usually smaller, place them near the work or study area where you want to stay cool, so that aeration is precise and punctual, but never subject yourself directly to the flow of air: you could cool yourself by exposing yourself to harmful currents. When the desk fan is not in use, you can easily move it to a smaller room, bookcase or closet.
Fan vs air conditioner
Of course, an air conditioner cools the air to the desired temperature; it can also remove humidity or add it where it is needed, it is comfortable and practical. It cools even large rooms, and it can also heat in the cold season if it is an air conditioner with several functions. Still, a fan's advantages in certain situations are diverse and all worth attention, as they can affect both the individual consumer and the community.
- Low cost: first of all, a fan can cost much, much less than an air conditioner, and this is a definite advantage if our economic possibilities at a given moment do not allow us to buy an air conditioner or air cooler.
- Healthy cooling: a fan produces an immediate and, above all, healthy cooling effect: the fan reduces the discomfort of the sultriness and the great heat, without modifying the air quality, which remains the same, as it's only moved more quickly. Of course, avoid exposing yourself directly to the airflow to avoid cooling down in a harmful way.
- Ease of installation: a fan does not require the complicated installation needed for an air conditioner, with electrical work and extensive wall work: the fan only needs to be connected to the power socket. The only type that requires more attention and some more work is the ceiling fan, for which, however, the required work is less than for the installation of an air conditioner.
- Low consumption: fans consume little energy, certainly much less than an air conditioner, lowering maintenance costs for the individual consumer. On the other hand, they do not affect collective energy consumption and, therefore, do not further burden the environment's quality.
- Ecological: last but not least, a fan does not modify the air quality. It does not have to discharge outside as happens with air conditioners, thus not burdening the environment's quality, representing, if not a benefit, at least not a danger for the environment and the community.
