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

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. |
