Flatmaster Wall Mounted Positive Input Ventilation System

Part of our Positive Input Ventilation range, the Flatmaster solution has been specifically designed to ventilate homes without lofts and is recommended for planned and reactive ventilation servicing. Suitable as a social housing ventilation solution, the system introduces air into the home at a continuously low rate, eliminating condensation dampness and forcing out indoor pollutants such as Radon gas and carbon monoxide. Allergens are kept to a minimum and outdoor pollutants such as pollen and traffic fumes are kept out. The results are a fresh and healthy indoor environment.
