Vents SR 315/1200 Silencer Galvanized 100 CM / Ø 315 MM Flanges

Length 120 cm and Ø315 mm connection flanges.

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

Vents SR Silencers are applied for noise absorption produced during the ventilating equipment operation and spread along the ducting systems. Suitable for installation into round ducts. The silencer reduces the noise level in the air duct significantly. For designing a ventilation system with low level of noise emission into the environment silencers should be used together with insulated fans.

The galvanized steel casing of the SR silencer is filled with flameproof sound insulating material and equipped with protecting covering against fiber blowing-out. The silencers are equipped with connecting flanges with rubber sealing for airtight connection to the air ducts.

MOUNTING
The silencers can be mounted in any position. Installing several silencers in series is preferable to improve sound absorption effect. To prevent the flexible silencer sagging it should be fixed not only at the ends but also in the middle.

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.
