Wind-driven rotary smoke extractor in stainless steel, chimney hood, 110 mm rotating exhaust grille, rotating smoke extractor for stove

201 stainless steel hood: Robust and durable, weather and rain resistant, high ventilation speed, zero energy consumption, and silent 360° rotation. Efficient ventilation and extraction, optimal air circulation. The turbine blades remain deformable even at high speeds. Galvanized roller: The hood's robust construction allows it to withstand winds of 200 km/h and a load of 100 kg without deformation or damage. Reduced temperature: In summer, the rotating fan limits heat buildup inside, thus lowering the temperature and creating a comfortable working environment. Non-return valves: The curved blades prevent rainwater infiltration. High extraction efficiency and ease of use. The variable-angle chimney neck design allows for easy installation with a slope from 0 to 22.5°. Suitable for residential, industrial, and commercial applications. Guaranteed energy savings. Installed on the chimney flue, the hood consumes no energy and operates using wind power. The stronger the wind, the faster the rotation and air circulation. It is used for bathrooms, kitchens, warehouses, houses, apartments, chimneys, courtyards, factory roofs, ventilation ducts, air vents, and exterior wall ventilation. It prevents pipe blockages caused by nests and debris.
