Brief Introduction
The duct silencer is a type of impedance silencer. It features small size and simple structure, so it has a wide range of applications.

Structure
The inner wall of the silencing cavity is filled with centrifugal glass wool, externally 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 air velocity of 6m/s)
