How to Choose the Right Ceiling Fan ?
Size
Size is really important when selecting your ceiling fan. If a fan is too large, it can overwhelm the space.
On the flip side, if the fan is too small, the airflow may be inadequate for that area.
30 m2 or more
18 - 30m2
12 - 18m2
12m2 or less
over Ø150cm
Ø130-150cm
Ø105-130cm
Ø70-105cm
How low should my ceiling fan hang?
For optimal circulation the fan should be at least 210cm and maximum 260cm off the floor to allow optimal circulation. For higher ceilings, use fans with downrods to achieve the right height.
Low Ceilings: For rooms with ceilings lower than 240cm or shorter flushmount “hugger” fans are the ideal option. As the name suggests, these fans “hug” the ceiling to create a low profile. In order to achieve their short height, these flush mount fans do not incorporate downrods in their design.
Average and High Ceilings: To hang a fan at the appropriate height in a room with a ceiling 240cm high or higher, a ceiling fan that uses a downrod is the right fit. Additional downrods ranges from 90 to 2000cm inches in length and is what suspends the fan from the canopy. This is ideal because more space between the fan blades and the ceiling results in better air circulation.
What is AIRFLOW m³/min?
Airflow quantifies the amount of air a ceiling fan delivers and is measured in cubicmeters by minute (m³/min). M³/min measurements are taken when a fan is on high speed. This means that the higher the CFM, the more efficient the fan, and the more air it moves.
What m³/min is best?
On high speed:
Good CFM ranges from 100 to 140
Better ranges from 140 to 180
Best is over 180
What is RPM ?
The RPM (rotations per minute) of a ceiling fan is the number of times its blades complete a full rotation in one minute. A higher ceiling fan RPM means faster and more powerful direct air movement, while a lower RPM means slower and gentler air movement.
Higher AIRFLOW or higher RPM ?
Airflow and RPM are not necessary always related to each other. For example our ceiling fan Ø81cm JUST FAN XS has a RPM of 235 with an Airflow of 122m³/min and our Solid Wood Ceiling Fan ECO AIRSCREW Ø152cm has a RPM of 125 with an Airflow of 195m³/min.
Generally speaking Higher RPM means more Wind below and within the immediate distances of the Fan instead of a higher Airflow circulates the Air in the Room much more.
If you like to feel the breeze and direct wind than a ceiling fan with high RPM is suggested, if you prefer a higher Airflow which for example circulates the cold air of the Air Condition sitting on the bottom of the room faster and more for a better overall room climate than a ceiling fan with a higher Airflow is suggested. Beside this general illustration what is the main difference between Airflow and RPM you will find in our big selection the perfect combination of both.
What is better? 2,3, 4 or 5 wings
How many blades does a ceiling fan have to have to be efficient? Which is better: 2, 3, 4 or 5 wings? What number of sashes is optimal for my living space?
Is it true that the number of blades determines the performance of a ceiling fan? The number of blades actually determines the air output of a fan. However, the profile of the wings is also important. A fan blade that is optimally profiled, i.e. twisted, conveys more air than a smooth blade. To compensate for this, we have equipped all of our decorative ceiling fans with 5 wooden blades instead of 4. This guarantees smoother running. The angle of attack of the wings is optimized for engine performance.
What other factors determine the air output of a ceiling fan? In a very simplified form, the following points are crucial for the air output AND the range of a ceiling fan:
- The total area of ​​all wings
- The angle of attack of the wings to the horizontal axis
- The speed of the engine under load
For example, a ceiling fan (with the same diameter) with 3 blades can have more than twice the air volume and three times the range as a ceiling fan with 5 blades.
But be careful: all of the factors mentioned must be coordinated with one another. It is not enough to arbitrarily increase the angle of attack of the wings. The profiling of the wing becomes enormously important as the angle of attack increases. Because a wing with no or poor profile produces one thing in the first place: an extremely loud noise!
Decades of experience make the difference.
We proudly look back on 25 years of experience in the development, production and distribution of ceiling fans. Some of our models have become classics over the years. Thousands of satisfied customers speak for themselves.
This advantage in experience is constantly incorporated into newly developed models.
All products must meet our strict quality and performance criteria before we can
recommend them to you.
Not every ceiling fan is suitable for every purpose.
Ask us if you have special requirements for your ceiling fan beyond its decorative purpose.
We will be happy to help you choose the right product and solve your specific problem.
With all our ceiling fans you can be sure that the factors mentioned are optimally coordinated. Air performance, range of airflow, energy consumption and noise are optimized and differ significantly from products that are sold in cheap markets, although they look similar.
You will enjoy and use your ceiling fan for a long time.

Should I buy a ceiling fan with light?
Combining function with practicality, our ceiling fans with lights illuminate whilst also creating a pleasant indoor climate.
Start by determining how much light is already available in the room and how much light you need: Factors to consider are whether it’s a relatively open space with lots of windows or sliding glass doors that let in natural sunlight, how many lamps are already in place and whether they provide adequate lighting. These considerations will dictate whether the fan should have a light.
For the ultimate control over the amount of light in a room, a ceiling fan with a light or a light kit may be the best option. Ceiling fans with ligh provide ample, even light that can be beneficial to all types of spaces. And many light kits are compatible with a wall dimmer or remote, so adjusting the light intensity or in some models even the color temperature is as easy as pressing a button.
Air flows in ceiling fans in summer operation
Air flows in ceilig fans in summer operation
When a ceiling fan runs forward (in Summer Mode), a distinction is made between the main air flow and the secondary air flow. The main vertical air flow forms a circle with approximately 1.3 times the diameter of the ceiling fan (B). The maximum air velocity in the main air stream at head/shoulder height in a room with a 3 m ceiling height is shown in the tables on pages 122 to 125.
The secondary air flow (C) is an area in which the air speed decreases towards the outside due to directional deflection and turbulence. The flow is diagonal to horizontal. The area of ​​the secondary air flow is a circular area with approximately 2.4 times the diameter of the fan. These areas are the basis for the design of ceiling fans for summer ventilation in any room.
Basically, it should be borne in mind that when selecting the size, it may make sense to choose the next larger model if the structural conditions allow this. A slightly larger ceiling fan can run slower than a smaller model to deliver the same amount of air. This results in reserves that can be helpful in the event of very high temperatures.
