The UK’s first ever Positive Input Ventilation (PIV) system – and still the market leader after more than 50 years – the Drimaster, from Nuaire, has evolved once more.
The Drimaster-Eco has swapped its casing from a virgin ABS plastic to a recycled plastic. The switch will result in a reduction of 167 tons of equivalent embodied carbon over the period of a year.
PIV technology was invented by Nuaire in 1972 and is recognised as an effective means of reducing condensation dampness and its associated problems within residential properties. PIV systems draw outside air from the loft space, filter that air, then gently disperse it into the home via a central diffuser at a continuous rate. This creates a slight positive pressure within the home that moves stale, damp air and pollutants out through the natural leakage gaps found in every UK property, both old and new.
Tried and tested, Drimaster PIV units are installed in over a million homes in the UK, and are particularly popular with social housing providers due to their cost-effectiveness, speedy install (Drimaster-Eco can be installed in a loft in less than an hour), longevity (many Nuaire Drimaster PIVs have been in operation for over 20 years), and non-disruptive nature for residents.

Moving from the virgin ABS plastic to 100% recycled plastic will not impact the quality of the Nuaire Drimaster-Eco PIV units, although customers will notice a change in colour from the blue plastic to black. The units will continue to be made in Nuaire’s South Wales state-of-the-art manufacturing facility that covers over 71,000 square metres and operates with minimal impact on the environment.
Nuaire technology evolution
Nuaire’s PIV technology and product range has continually evolved since the first iteration in 1972, with the latest incarnation – the Drimaster-Eco – using up to 20% less energy, meaning lower running and life cycle costs.
In addition to the standard Drimaster-Eco, the Drimaster-Eco NOX is available which comes with two carbon cartridges which reduces NOX levels – a dangerous pollutant commonly caused by road traffic – within the home by up to 80%. Drimaster models are available with a 400W heating element fitted on the diffuser to temper the airflow should the temperature in the loft space drop below a set point, ensuring ultimate comfort in the home. For homes without lofts, the Flatmaster PIV unit is available.

This latest product development comes on the back of Nuaire’s announcement of its switch to the use of XCarb® low carbon-emissions recycled and renewably produced steel on many commercial units, which will directly result in a 68% reduction in CO2 emissions, and the use of recycled plastic for its ducting. As part of the Genuit Group, which has pledged to be net zero by 2050, Nuaire has set rigorous carbon reduction targets and, in 2024 alone, removed 2,000 tons of carbon from its product portfolio.
