Nuaire invents Positive Input Ventilation

It was in 1972 that Nuaire invented a cure for condensation dampness in residential properties and its associated problems. Installed in over a million homes Positive Input Ventilation (PIV) - is the UK’s most popular method of low-energy whole home ventilation.

Nearly 50 years later, Nuaire’s retains its number one position in the market by continually enhancing the product and meet the ever increasing demands in the marketplace. Fresh air is drawn through the loft by the PIV unit, filtered and passes via the ceiling diffuser, creating a positive pressure within the home forcing air pollutants out through the natural leakage gaps found in every home.

Nuaire’s market-leading Drimaster-eco range is designed for 2 and 3 storey homes with lofts, while the Flatmaster is designed for flats, apartments and basements. Both ranges are quick, cost-effective, and easy to install and maintain, making them an ideal solution for both new build and retro-fit applications.

PIV is a fit-and-forget technology that requires minimal energy to run and minimum effort to maintain. The PIV strategy, also known as an Alternative System 5 within Part F of building regulations, works by gently introducing fresh, filtered air into the dwelling ensuring that old, contaminated moisture-laden air is continuously diluted, displaced, and replaced with good quality air. The result is improved air quality and a healthy living environment in which condensation cannot exist. Both Drimaster-Eco and Flatmaster PIV ranges have been designed to eliminate condensation and improve the quality of air inside the property.
