Exterior Fan Silencer
By: WhisperRoom™
April 30, 2019

Exterior ventilation fans have a 38dB noise rating. This slight noise can be eliminated by positioning each fan into an Exterior Fan Silencer (EFS).
The number of EFS units needed depends on the size of the WhisperRoom™ and the number of ventilation systems required. This option may be required when a more controlled sound environment is needed in the host room.
Note: May be ordered and installed at any time.
