Brief Introduction
The duct silencer is one type of impedance silencer. It features compact size and simple structure, thus being widely applied.

Structure
The inner wall of the silencing cavity is filled with centrifugal glass wool, covered with glass cloth and perforated plate with a hole diameter of Φ3mm. The thickness of the air deflector is 100mm.

Main Technical Parameters
Noise reduction: 18.5dB(A)
Pressure loss: 2mmH₂O (at an air velocity of 6m/s)
