Description

The silencer is used for attenuation of the operation noise generated by ventilation equipment and spreaded in the the air ducts. Designed for connection to round air ducts.

The SD silencer has a polymer-coated steel casing filled with noncombustible material that has a protective coating to prevent fiber deformation.

Noise level reduction

The values shown in the tables represent the difference between the sound power level (Lw) of the combination of the fan, the attenuator and the power of one fan.

To determine the sound power level of the fan equipped with a silencer, the insertion loss must be subtracted from the rated sound power level (Lw) of the fan on the mid-frequency spectrum in the octave band given in the fan specifications.
