The DRI-365 is the height of Positive Input Ventilation (PIV) designed to run all year round!

The Drimaster-Eco range offers cost-effective, whole home ventilation solutions suitable for properties with a loft space, which will cure condensation dampness and remove allergens and pollutants from the home.

The unit intelligently utilises solar gain from the loft space during colder months, whereas during warmer months it will automatically choose to source its air supply from directly outside the property and then introduce fresh, filtered air.

You’ll benefit from improved indoor air quality as condensation dampness is cured, whilst allergens and pollutants are removed from the home. 

Installed in the loft out of sight and with no holes to knock through walls, this is the perfect solution for homes looking for a ventilation solution!




The DRI-365 operates all year round and is a low-energy whole home ventilation system. Suitable for all properties with a loft space. 

The unit is fully automatic and intelligently decides whether to source its air supply from the loft space or directly from outside based on air temperature. The unit is fitted in the loft, out of sight and is easy to install and cheap to run.

DRI-365 filters only require replacement every five years, so maintenance is minimal, allowing you to fit and forget your unit while you enjoy year-round benefits.

Positive Input Ventilation (PIV) is a principle where fresh, filtered air is introduced into the home at a continuous rate, encouraging movement of air from inside to outside. This process removes condensation, allergens such as pollen and dust mites as well as the pollutants caused by cooking and cleaning, from the air. This results in a fresh and healthy indoor environment in which condensation and mould cannot exist, and where indoor pollutants including harmful Radon gas are kept to a minimum.
