APPLICATIONS DESIGN

Silencer is 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 (refer the diagram «Noise
level reduction»). 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.
