Description
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 SDV silencer has a polymer-coated steel casing filled with noncombustible material that has a protective coating to prevent fiber deformation. The silencer has an internal sound-absorbing element to increase sound attenuation efficiency.

Noise level reduction
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.
