Vents Silencer Galvanized 50 CM / Ø 315 MM Flanges

Length 50 cm and Ø250 mm connection flanges.

Silencer to reduce noise from air extractor fans, as well as voice sounds. Equipped with standard size flanges.

Easily-fitted silencer for circular ducts, fitted with a connection that complies with the spiral duct standard. The tubular silencer effectively reduces noise in the duct. Two silencers can be used together in installations where noise reduction is a particularly strong requirement. This is very effective.
For the most effective noise reduction, the silencer should be fitted immediately behind a fan or bend. The silencer should be used together with an insulated fan and ducting, where there is a requirement for noise reduction both in the duct and in the surroundings as a whole.
