For any weather...

Normal Conditions

Under normal conditions, the Monodraught Windcatcher technology provides natural ventilation without any moving parts. Any prevailing wind no matter how light is encapsulated by the air intake louvres and turned through 90°. Using compartmentalised vertical vents, fresh air is brought into the room and stale warm air expelled using the natural energy of buoyancy and stack effect.

Sunny Conditions

It is on hot, sunny days when extra ventilation may be required. The Windcatcher Sola-boost solar-powered fan provides additional ventilation when extra air movement is needed most!

Sola-boost systems can be used on virtually any building. For example the Sola-boost system can be used to overcome excessive heat gains created by large levels of external glazing where solar gain is at its highest.

The Sola‑boost system provides the comfort of knowing that it will provide a constant supply of ventilation air, even when there is no wind. This guarantees a zero energy solution allowing the building’s natural ventilation design to be optimised and ensuring a low energy natural ventilation strategy to be maintained.
