Rotating chimney cowls, deflectors, turbines or caps are designed for installation on ventilation shafts or ventilation pipes to improve air draft. Productivity depends on wind speed. When the wind blows into the cowl cap, it rotates, creating negative pressure in the ventilation system and improves air draft. The stronger the wind - the better air draft (average wind speed at an altitude of 10 m, in Lithuania 4.5-5.5 m / s).
