In any building or structure there is a ventilation system that is responsible for the exhaust in the room. The pipe facing the street usually ends with some solution: either a traditional fixed ventilation poles,or a wind-driven ventilation turbine. A ventilation turbine solves this problem much more efficiently than conventional ventilation turbines, without using electricity for this purpose. Practice has shown that ventilation turbines made of metal, in addition to the obvious advantages, have a lot of disadvantages, which is why consumers choose traditional solutions.
