A quiet, silent ceiling fan is a testament to quality!

Basically, all of our ceiling fans are low noise and quiet ceiling fans by design.

Noise ceiling fans can have 3 causes:

1. Quiet / low noise ceiling fan: wind and air noise in ceiling fans

The blade profile, the angle of attack and the motor speed under load determine the air performance of a ceiling fan, but also the noise generated by the blades during operation. These 3 factors always represent a compromise in relation to the air noise. It should be borne in mind that for a ceiling fan with 200 rpm and a diameter of 160 cm, the blade tips have a speed of about 63 km/h! This illustrates why poorly profiltered blades "flap", i.e. produce a fluttering noise, at high speed levels.
All CasaFan, Hunter and Fanimation models for home and residential use are very quiet and low-noise ceiling fans and are designed to be suitable for living spaces in terms of air noise, even at full power.

2. Quiet and low noise ceiling fan: motor and bearing noise in ceiling fans

When a motor is in operation, it creates mechanical friction in the bearings and thus a noise. The quality of the ball bearings, among other things, decisively determines the volume of the resulting noise. If savings are made here, the result will sooner or later be a grinding, grating noise. Due to its low frequencies, this is particularly unpleasant and clearly perceptible. Often, this noise occurs only after a certain operating time, which is not infrequently outside the warranty period. When buying a ceiling fan, make sure that it has two closed, maintenance-free and self-lubricating stainless steel ball bearings. This will guarantee long, worry-free operation of your quiet, silent ceiling fan. Not all products on the market, especially those from construction and cheap markets, have this quality feature. Furthermore, the design of a motor determines whether or not the alternating electromagnetic field required to drive the motor will make itself heard during operation. Cheap ceiling fans are often so economically designed that the operating noise of the motor is loud and clearly perceptible. Such a designed model can never be a quiet and silent  ceiling fan.

3. Quiet and low noise ceiling fan: resonance noise in ceiling fans

Resonance noise, due to its pervasive main interference frequency, is particularly unpleasant in living and sleeping areas. Quiet and restful sleep is not possible in a bedroom where there is a ceiling fan that develops resonance noise. Any motor, whether that of a microwave or a pump, causes vibrations. These vibrations are usually not noticeable in good quality brand ceiling fans - the fan itself is a quiet and silent ceiling fan. However, they are transmitted through fixed components of the fan to the suspension (resonances). If the ceiling fan is attached to a part of the ceiling that is not permanently suspended, it will cause it to vibrate. Often this happens with suspended ceilings, usually wooden ceilings or plasterboard ceilings. Therefore, when mounting a ceiling fan, the mounting location must be chosen carefully. There are measures to interrupt the sound path and acoustically decouple the equipment, making the ceiling fan quieter and less noisy. But often these measures only reduce the noise instead of stopping it completely. If the resonance originates on the unit itself, probably too little care was taken to avoid resonance when the ceiling fan was designed. Then the device should be replaced with a higher quality model, a quiet ceiling fan.
