Sola-boost system from Monodraught

The Sola-boost is an extension of the Windcatcher design, to provide additional ventilation on sunny days whilst maintaining zero running costs.

Monodraught have significantly improved the potential of Windcatcher systems by the addition of a solar driven internal fan that brings in additional fresh air up to 260l/s. Conversely, the fan operation can be set to extract stale air - all this without any energy cost. A unique feature of the system is the PowerTrack™ control system. This system works on the basis that the brighter the sun, the greater the speed of the boost fan. The switching results in 2½ times more power from the solar panel than can otherwise be achieved by a direct connection.
