The Simply Silent Contour CV range uses Intelligent Adaptiflow Sensing to deliver a constant volume performance.

A unique sensor is located in the duct airflow and is continuously calculating and recording the flow rate, taking hundreds of measurements each second. When the technology senses consistent changes in airflow, brought about by reduced ducting efficiency or a strong wind applying back pressure in the duct, it adapts the fan intuitively to maintain a constant volume of extracted air.

Intelligent Adaptiflow!" Sensing works cooperatively with the product s active humidistat. This means that when the humidity increases rapidly, or reaches the fan s pre-set humidity level then the required flow rate increases. The sensor will reflect this in the information it is sending to the fan s high speed central processor. The benefit of Intelligent Adaptiflow!" Sensing delivering constant volume performance is that the homeowner can be assured that the desired airflow is achieved for the lifetime of the product.
