Description
This truly original product of our company is unparalleled in the field of turbine ventilators. This ventilator works as a hybrid element, i.e. it is powered by:
a) wind, or
b) electricity
The operation of the ventilator is controlled by an electronic unit which switches on the driving electric motor as needed. Energy consumption is negligible, as the power supply is 6 W only.
