Alsynite One Industrial Turbine Ventilators use renewable wind energy to create a positive flow through the ventilator. Even the slightest wind speeds will cause the head to spin. An area of low pressure is created on the leeward side of the vent and the air drawn out between the vanes on the head of the ventilator feed this low pressure zone.
This process allows for a continuous airflow through the vent. The centripetal forces created by the rotation of the vent will expel the air outwards from the edge of the vanes and this hot and stale air is replaced by cooler and fresh air from outside the building. Thermal currents and temperature differentials will also allow the ventilation process with the vent, even with no wind.

Available in; 150mm, 300mm, 600mm and 900mm
