Silencer SRF VENTS Ø200/600mm

Applications

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. 

Design

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 SRF silencer casing consists of internal and external aluminum-alloy spiral seam tubes filled with  flameproof sound insulating material. The casing  inner surface is perforated and has the protecting  over to prevent the fiber blowing-out. The minimum  bending radius of the silencer is up to 2 diameters. Each standards size has several length modifications. The SR and SRF 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.
