Significantly improve condensation dampness and remove allergens and pollutants from the home with the low-energy ventilation system, from the inventors of PIV. The Flatmaster offers a low-cost, whole home ventilation solution for homes without lofts. Based on the popular and low-energy Positive Input Ventilation principle which Nuaire invented in 1972, the Flatmaster has been specifically designed to ventilate homes without lofts. The system introduces air into the home at a continuous low rate, eliminating condensation dampness and forcing our 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. The aesthetically pleasing and compact unit is usually situated in a convenient location, such as a kitchen cupboard or hallway, and is ducted to a central location. Multi-positional spigots allow for quicker installation with only one external wall penetration.
