Silencer Round VENTS SR 125/900
The silencer is used to absorb noise generated by ventilation equipment and spreading through the air ducts of ventilation systems. It is used for installation in round ducts. It significantly reduces the noise level in the air duct. The silencer is used together with a sound-insulated fan in cases where noise reduction requirements apply not only to the air duct, but also to the equipment as a whole. The CP silencer body, made of galvanized steel, is filled with non-flammable sound-absorbing material with a protective coating (from fiber blowing). The silencer is equipped with connecting flanges with a rubber seal for a hermetic connection with the air ducts.
The design of the muffler allows it to be fixed on round air ducts using clamps in any position. The best effect can be achieved by installing mufflers sequentially one after another. To prevent the flexible muffler from sagging, it is necessary to fix it not only at the edges, but also in the middle.
