Silencers are an element of the air exchange system that is installed in the air duct system to reduce the aerodynamic noise created by fans. This is not the main, but additional equipment that helps to comfortably control the air supply and exhaust system. The vibrations created by fans and transmitted by air through a network of air ducts can cause severe discomfort and also shorten the service life of all elements. Long-distance air ducts transmit these noises well, the hum of which can be heard even far from the noise source. This is why it is important to reduce noise in your duct network.
