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»). The silencer is applied jointly with the sound-insulated fan in case of low-noise requirements not only to the air duct but to the equipment altogether. |
SRF silencer casing consists of internal and external aluminium-alloy spiral seam tubes filled with flameproof sound insulating material. The casing external surface is perforated and has the protecting cover 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. |
MOUNTING | |
The silencer design allows fixing it on the round ducts in any position by means of clamps. The linear mounting is preferable for to attain the better effect. To prevent the flexible silencer sagging it should be fixed not only at the ends but in the middle. |
