Envirovent EFHT2S-STD-230V-BDS Filterless Extractor Fan 230V Backdraught Shutter

The FILTERLESS FAN is a continuous running extractor fan suitable for WCs, bathrooms, utility rooms and kitchens. It is a major advancement in extractor fan technology; it utilises a centrifugal impeller and our Intellitrac technology which ensures extremely high airflow performance and humidity levels are controlled all year round.

Intellitrac is a unique intelligent vapour tracking control that constantly monitors the humidity levels within the wet room. As humidity rises and falls, the motor speed rises and falls in direct correlation to ensure humidity levels do not increase. The FILTERLESS FAN range has an increased Trickle+ airflow setting, making meeting the Approved Document F airflow rates as easy as possible. This range is one of the most versatile fans on the market and can be installed on walls, ceilings, windows and even inline making it suitable for every scenario.
