Sound attenuator SRF 150/600, aluminium alloy, spigot dimensions 150 mm, tube diameter 150 mm, length 600 mmApplication rangeDampening of the noise generated during operation of the ventilators and arising in the air. Ensures a significant reduction of the noise level in the duct (see table of noise reduction) For the creation of a sound insulated ventilation system, we recommend the use of sound absorbers together with sound insulated fans. the housing of the sound absorber SR is made of galvanized steel and filled with a sound absorbing material from the inside. The protective layer of sound-absorbing fabric prevents the inner fibres from being pulled out. The housing of the sound absorber SRF consists of an outer and inner spiral duct made of aluminium alloy. The inner tube is filled from the inside with a sound-absorbing fabric. The inner surface is perforated and provided with a protective layer that prevents the inner fibres from being pulled out. The muffler can be bent with a minimum radius of up to twice the diameter. For every standard size, there are several variants of the sound insulation available. SR and SRF mufflers are equipped with rubber-sealed connecting flanges for tight connection to ventilation ducts. installation The mufflers must be installed in any position. A better sound-absorbing effect can be achieved by connecting the sound absorbers in a row. To prevent the flexible muffler from sagging, it should not only be attached to the cabinet but also to the centre of the cabinet.
