The Envirovent PIV Loft Mounted Unit is a positive input ventilation for houses with a loft space and radon problems.
Beyond traditional input ventilation, the PIV Air Source unit has the facility to source cooler air from outside the building when the temperature in the loft space rises above 25°C. Detecting the rise in temperature, the unit starts to draw air from atmosphere via a temperature controlled diverter mechanism.
This not only provides efficient perception cooling into the property during warmer weather, but also maintains the required level of ventilation continuously throughout the year. This facility is greatly beneficial for properties affected by high levels of radon gas emissions.
