Fans (35)

A wide selection of fans to keep you fresh in summer. Find them at Klarstein

Every year, as summer approaches, it’s customary to see an exponential increase in the purchase of air conditioners, air coolers and other devices to cope with above-average temperatures. Buying an air conditioner seems an expensive solution? Then, the most practical and economical device to protect yourself from the incoming heat is certainly a fan. This appliance will make all the difference for just a few tens of pounds, ensuring an immediate sensation of coolness thanks to its extreme versatility.

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 fan 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. Browse our product gallery and find out which one is right for you.

The working principle of a fan

Unlike air conditioning, ventilation has a straightforward operation. The air displacement generated by a fan in the room sets cold and warm flows in motion. This increases 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 fan. 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 fan 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 m²On 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 fan: is the type of fan that provides the most uniform airflow. It is suitable for large rooms and is often equipped with ceiling light with a lamp 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 of ceiling fans can reverse the airflow, to prevent hot and cold air from staying only in certain areas of the ventilated environment and thus to allow a healthy change of air.

  • Tower fan: they do not use a propeller to generate the airflow, as they rely on a wheel fitted with blades, which rotates in its casing, and the expelled air may or may not be channelled. Less noisy than axial fans, centrifugal or column 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: on the other hand, tower fans are not so effective when it is necessary to cool a large room.

  • Free-standing fan: it’s designed for more restrained ventilation. Usually smaller in size, free-standing oscillating fans are only able to provide cooling to well-defined and limited areas. 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 fan. Obviously, the larger the fan, the larger the room you can cool with it. It should be noted, 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 need most.

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 on 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, or in front of the most inhabited and frequented area of the room; 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 that you want to 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, it can easily be moved to a smaller room, bookcase or closet.

Advanced features of a fan

Moving air is by definition the purpose of an electric fan, but some fans 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 on a fan 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 balance between positive ions (cations) and negative ions (anions) must be respected. 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.

Advantages of a fan over an 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, care must be taken not to subject directly to the airflow not to risk 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 work required is less than for the installation of an air conditioner.

  • Low consumption: fans consume little energy, certainly much less than an air conditioner. This lowers 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.
