This Drimaster Eco unit is designed for three storey buildings, providing positive input ventilation for properties with lofts.



Nuaire PIV

The Nuaire Drimaster Eco 3 Storey Positive Input Ventilator provides whole home ventilation using the Positive Input Ventilation (PIV) principle. PIV systems provide a cure for condensation dampness by reducing the humidity in the air. This effectively prevents mould growth and related issues that can be a particular problem in rented accommodation.

The Drimaster Eco unit is ideal for rented three storey properties as all controls are located on the main loft unit, meaning tenants don’t have easy access to change any settings. The unit also complies with fire regulation standards for three storey properties with stairwells.

Positive Input Ventilation

As a positive input ventilation system, the Drimaster Eco works by introducing fresh, filtered air into your home at a continuous rate, encouraging the movement of air from inside to outside the property. The PIV unit is mounted in the loft where it draws air through specially-designed Nuaire Drimaster filters before inputting into your home at ceiling level. The filters remove pollutants such as Radon gas, pollen, and traffic fumes delivering better indoor air quality. Overall this makes for a healthier living environment, in particular for allergy sufferers and those with asthma.

The Drimaster Nuaire units are fitted with an internal temperature sensor, which continuously monitors the temperature in the loft. This allows it to switch to heat recovery mode and boost the air volume when the temperature in the loft-space goes above a certain pre-set temperature. When the loft temperature goes above 23 degrees, the unit switches to standby mode and airflow is prevented. 

Nuaire Drimaster Installation

The Drimaster unit is mounted in the loft space. Once installed, you can set the airflow to suit the size of house and respond to changes in temperature within your property. You will be provided with full Drimaster installation instructions. Installation is easy and simple, taking under an hour.
