Silencer SRF 200/600, aluminium alloy, spigot dimensions 200 mm, ventilation pipe diameter 200 mm, lambs 600 mm

SRF 200/600 silencer, aluminium alloy, socket dimensions 200 mm, ventilation pipe diameter 200 mm, length 600 mmApplication rangeAttenuation of noise generated during operation of the ventilation units and propagated in the air ducts of the ventilation systems. Ensures a significant reduction of the noise level in the air duct (see the noise reduction table) To create a sound insulated ventilation system, the use of silencers together with sound insulated fans is recommended. the housing of the silencer SR is made of galvanized steel and filled with a sound absorbing material from the inside. The protective layer of muffling material prevents the inner fibres from being pulled out. The housing of the SRF silencer consists of an outer and inner spiral duct made of aluminium alloy The inner tube is filled from the inside with a sound absorbing material. The inner surface is perforated and provided with a protective layer that prevents the inner fibres from being pulled out. The silencer can be bent with a minimum radius of up to twice the diameter. For each standard size there are several variants of the silencer length SR and SRF silencers are equipped with rubber-sealed connecting flanges for tight connection to ventilation pipes. A better sound-absorbing effect can be achieved by connecting the silencers in rows. In order to prevent the flexible silencer from sagging, it must not only be attached to the edges but also to the centre of the silencer.
