The Simply Silent Contour CV and LVCV models have been designed to offer exceptionally low noise levels, whilst delivering a constant volume of extracted air to eliminate humidity, condensation and mould growth in bathrooms, shower rooms, cloakrooms, toilets and kitchens. These fans feature Xpelair’s Intelligent Adaptiflow Sensing to deliver constant volume performance through a unique sensor housed within the duct. The sensor calculates and records the airflow of the fan and adapts the fan speed intuitively in accordance with changes in air-flow to maintain the required setting. They have selectable bathroom or kitchen airflows, with three operating speeds in each mode. They use advanced Ghost Air Movement Technology to deliver near-silent running and are suitable for wall, ceiling, panel and window fitting. Both CV and LVCV models are supplied with a circular and a square baffle to suit your preferred styling.
