Brink Sound Dampening Wall Bushing for Sonair 3.0 In Home Ventilation ) 5 °C Installation TemperatureThe Sonair 3. 0 installation requires the Sonair to be installed on the inside of an external wall. To do so, a hole must first be drilled in the external wall, a duct inserted in the hole and a grille fixed on the external wall. Brink recommends using a special sound dampening duct when installing a Sonair 3. 0 ventilation unit. When using this dampening wall bushing with a diameter of 100 mm, a 102 mm hole must be drilled in the outside wall.
