It is practically impossible to prevent a fan from generating a certain level of noise. Just as air conditioning manufacturers always try to offer silent products - since they also incorporate fans inside -, in all mechanical ventilation systems they always try to reduce the decibel level as much as possible. In some cases, we can reduce the noise until we find a level of quiet ventilation that is comfortable for us. Avoiding noise completely will always be impossible, since the rotation of the propellers, the speed of the air or even the engine will generate sounds that cannot be ignored. However, silent ventilation can be achieved if we can achieve a really low and comfortable acoustic level. And for this we have different solutions to implement. Before choosing silent fans , we have to think about the use that they are going to be given and their plac
ement. For example, in the case of bathroom extractors it is important that they do not generate a lot of noise. How to enjoy silent ventilation? Aesthetic ventilation grilles Chinese Overseas Africa Number Data The most obvious thing is to opt for a fan that works at lower power. With a lower number of revolutions, the noise will undoubtedly decrease. Even so, it must continue to maintain a flow rate and pressure that guarantee the comfort for which the fan has been chosen. In this case, it is very important to know the needs of the ventilation system . For example, mechanical solutions that extract air from the home and renew it by introducing fresh air from outside have minimal needs to guarantee their optimal functioning. In this case, adhering to these specifications is important to avoid extra noise and decibels. Beyond that, to continue seeking silent ventilation , you can select a fan with a motor with a greater number of poles. For example, six poles and 900 revolutions per minute. We can also opt for fans with variable frequency, which allow us to choose how many revolutions it will operate at. We also have the alternative o
f choosing energy efficiency alternatives. All fans that save on electricity also save on noise. We have, for example, EC fans . They are models that combine alternating and direct voltage, using the best of each motor. They are powered by alternating current, but then transform the energy to direct voltage. In addition to saving a lot, they generate less noise. Smart installations We have previously mentioned that it is highly recommended to know where the fan will be installed and how it will operate. And it is a good option to use only the necessary power. However, the installation of the ventilation system is very important. The ducts through which the air will circulate are of utmost importance. If they connect to the outside, th
