Technical Specifications:

The Nuaire Drimaster 365 (DRI-365) provides whole home ventilation using the Positive Input Ventilation (PIV) principle. Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. To achieve this the Nuaire Drimaster 365 (DRI-365) unit is mounted in the loft space where it draws air either from the loft space through filters, or directly from outside via ducting and inputting it, at ceiling level, into the property.

Our range of NUAIRE DRIMASTER-ECO units are fitted with an internal temperature sensor. This sensor continuously monitors the temperature in the loft, boosting the air volume when the loft temperature is above a set level (heat recovery mode).

If the loft temperature becomes excessive the Nuaire Drimaster 365 (DRI-365) unit will automatically convert to drawing it’s air supply from outside the property via the fitted duct.

The Nuaire Drimaster 365 (DRI-365) provides whole home Positive Input Ventilation (PIV) for properties with lofts. The Nuaire Drimaster 365 (DRI-365) unit is mounted in the loft-space, and uses integral temperature sensors to dictate where its air supply comes from. If the loft space exceeds a set temperature then air is drawn from directly outside the property via fitted duct, whereas during colder months the warmer air will be utilised from the loft space; in both circumstances the air is filtered before entering the home via a ceiling diffuser.
