VENTS SRN 250/500

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. The silencer is applied jointly with the sound-insulated fan in case of high level requirements not only to the air duct but to the equipment altogether.

SRN silencer consists of the internal and external flexible air duct made of metallized polyether film. The ducts are reinforced by the scroll frame made of high-carbon steel wire. 25 mm mineral woollayer is laid between the air ducts. The silencer is equipped with connecting flanges with rubber sealing which provides the airtight connection to the air ducts. Each standards size has several length modifications.

The silencer design allows fixing it on the round ducts in any position by means of clamps. Installation in series is preferable to attain the better effect. To prevent the flexible silencer sagging it should be fixed not only at the ends but in the middle as well.
