Hybrid Turbowent chimney cowl is a device, which, in a dynamic way, use force of the wind to increase chimney draught. It is equipped with a low power brushless electric motor. When the wind speed is too small to achieve the desired efficiency, electric motor speeds the turbine up, when it is too strong it slows the turbine down. When the wind speed is strong enough to achieve the rotation speed set on the steering device, motor does not work, and cowl works just like the ordinary Turbowent.
This cowl was designed for industrial and multi storey-building ventilation
