One of two Positive Input Ventilation Systems, the Flatmaster is one the UK’s most popular methods of low-energy whole home ventilation. Designed for flats, apartments and basements, the Flatmaster is quick and easy to install and maintain. It’s a cost-effective solution for both new build and retro-fit properties which require reliable and efficient ventilation systems.

The Flatmaster range 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 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 result is a fresh and healthy indoor environment.

The aesthetically pleasing and compact unit is installed 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.
