★Multi-purpose: Rotary hood for ventilation ducts, chimneys and exhaust. The lacing provides maximum protection without hindering the performance of the chimney. Especially suitable for chimneys that are not frequently used. Stainless steel structure thickened fixed feet; includes a complete fixing kit. ★Perfect protection: thick stainless steel rotating chimney hood, rotating anti-sinking, suitable for most standard chimney hoods, very effective in preventing wind and increasing ventilation. Protect your chimney from rain and humidity, especially suitable for chimneys that are not frequently used. ★Rotating turbofan: the base diameter is suitable for most standard chimneys, the base diameter is 100mm, 110mm, 150mm, 160mm, 200mm, 300mm, 350mm, 400mm, 450mm, 500mm, suitable for standard solid steel chimneys (fixed) ★Unpowered roof vent: The turbo fan uses the convection theory of natural wind and air to accelerate the parallel airflow into vertical airflow, thereby improving indoor ventilation. The hot air rises and the cold air falls, which makes the fan rotate, so that the indoor heat, odor and dust can be effectively discharged. Energy saving and no electricity bill to reduce your electricity bill. ★No noise and rainproof: There is no noise when the roof ventilation fan rotates. The distance between the downwardly protruding slats is small enough to prevent rainwater from entering the ventilation system. The hat is designed to rotate with the action of the wind, so that the more the wind blows, the more the blades rotate, and the more powerful the air intake from the inside to the outside.
