Hybrid Turbowent chimney cowls are devices, which, in a dynamic way, use force of the wind to increase chimney draught. They are also 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 to the speed set on the steering device. 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.
It is to be mounted on gravitation based ventilation duct endings
Speed adjusting range: 90 - 300 [rev/min]

Power consumption: 2 ÷ 5 [W] ( depends on the working mode)
Power supply: 230[V] / 50 [Hz]
