The range of Zehnder Silent fans offer “whisper-quiet” operation – typically a minimum of 70% less noise than standard fans. This range has been developed in response to customers who want high performance ventilation without nuisance noise. 3 year warranty.
Adjustable over-run timer (2-30 mins) factory set at 15 minutes. When wired into room light or remote switch the fan will operate whilst the light is on and, when switched off, will run on over-run timer for the pre-set over-run period
