The silenced jet air outlet is constructed by installing jet silencing components at specified spacing and rows inside a rectangular (slot-type) or circular shell to form rectangular or circular silenced air outlets. It is made of high-quality sprayed galvanized steel plate or stainless steel with integral mould pressing and neat arrangement, ensuring attractive appearance and structural strength.
It adopts the silencing mechanism of acoustic total reflection critical angle, 90° angular phase delay frequency and throat acoustic impedance. When air passes through the jet silencing elements, an airflow channel similar to an acoustic blocking state is formed. Noise waves are greatly attenuated and filtered, while airflow is delivered at low resistance and high velocity without generating secondary noise, delivering remarkable silencing performance.
Application Places：Public buildings and high-rise buildings, including conference halls, lecture halls, restaurants, dance halls, exhibition halls, gymnasiums and other similar venues.
