Xpelair Simply Silent CV4SR Extract Fan

Xpelair Simply Silent CV4SR Extract Fan

Maintains a constant volume of extracted air ideal for south westerly facing installations

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 products active humidistat.

This means that when the humidity increases rapidly, or reaches the fans pre-set humidity level then the required flow rate increases.

The sensor will reflect this in the information it is sending to the fans high speed central processor.

Delivering constant volume performance is that the home-owner can be assured that the desired airflow is achieved for the lifetime of the product.
