Positive Input Ventilation

Invented by Nuaire in the 1970s, this enduring ventilation strategy has since become an industry staple. Nuaire’s market-leading Drimaster-Eco Positive Input Ventilation, or PIV, range is trusted by Social Housing providers, New Build developers, and and Private Landlords as a cost-effective, whole-house system that prevents condensation and black mould from damaging homes and the health of occupants.

Nuaire invents Positive Input Ventilation

It was in 1972 that Nuaire invented a cure for condensation dampness in residential properties and its associated problems. Nearly 50 years later, Nuaire’s innovative strategy - Positive Input Ventilation (PIV) - is the UK’s most popular method of low-energy whole home ventilation.

It works by gently pressurising the home from the inside out. Fresh, filtered air is brought into the unit and forced through a diffuser in the ceiling, which creates positive pressure throughout the home, eventually forcing air pollutants out through natural gaps such as windows, doors, and the letterbox.

Nuaire’s market-leading Drimaster 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 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.
