The Simply Silent™ DX100BS Standard fan operates via remote switching (ie. Pull switch, fan isolator switch) The Simply Silent™ DX two-speed, intermittent extractor fan range is designed for those looking for something conventional, with a modern twist. These fans feature a conventional grille-style fascia, finished in cool white and available in either round or square. The Simply Silent™ DX100 range of 100mm extract fans feature unique, innovation Ghost Air movement technology to deliver near-silent running. Fan noise comes from both the motor and the movement of air. To combat this, Ghost Air Movement Technology uses long-life silent running motors and precision engineered components to avoid mechanical noise, while advanced air flow management eliminates irregular air flow paths and turbulence.
