Passivent Ltd has developed a unique system, Flair, that links the kitchen extractor hood, and extracts in the wet rooms to one low energy fan discreetly positioned within the home, ducted through the wall.
The system minimises energy consumption whilst providing constant background ventilation without the noise associated with traditional mechanical extraction in these rooms. It also minimises maintenance and occupant input to ensure a wellventilated, odour and damp-free home.
Passivent Flair means all rooms are properly ventilated to Building Regulations, but using only one system and wiring loop instead of at least two, and minimising the number of penetrations through the building exterior.
The central, continuously running fan operates at low level until the cooker hood is switched on, which boosts the fan and opens a damper in the hood to extract cooking smells and moisture from the kitchen. Selfregulating, non-electrical extracts in the bathroom and en-suite automatically ensure the correct, preset level of ventilation is maintained, even when the system is boosted by operation of the cooker hood. Ducting links all extracts and is vented to a single wall terminal.
