Duct filled with phono-absorbing material, offering a more cost-effective and flexible alternative than silencers, Acoustic Ducting is used to reduce noises produced by ventilation and extractor fans in grow rooms and grow tents.
It's made from a perforated inner core that's identical to general standard ducting but with several small holes punched in it - It is then wrapped in a layer of glass-fibre and sealed by another layer of aluminium foil. As the air travels down the inner core the sound is let out through the holes into the glass-fibre, which deadens the sound.
In practice it reduces the noise of an extractor fan by around 60%-80%, and is almost always used with fans of 150mm and above, although all sizes of fans benefit from it's use.
