EJGMCNSGB

★Roof ventilation without power supply: The turbo fan uses the convection theory of natural wind and air to convert the parallel airflow into a vertical airflow, thereby improving indoor ventilation. The hot air rises and the cold air falls, which makes the fan rotate, so that the heat, odor and dust indoors can be effectively d. Energy saving and no electricity bill to reduce your electricity bill. ★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 (solid). ★Perfect Protection: Thick stainless steel rotating chimney hood, rotating chimney guard, suitable for most standard chimney hoods, very effective in ing wind and improving ventilation. Protect your chimney from rain and moisture, especially suitable for chimneys that are not used frequently. ★ Versatile: Rotating cover for ventilation ducts, chimneys and exhaust systems. The lacing offers maximum protection without affecting the performance of the chimney. Particularly suitable for chimneys that are not used frequently. Thickened feet made of stainless steel construction; complete mounting kit included. ★ Silent and rainproof: There is no noise when the roof ventilator rotates. The distance between the downward-projecting slats is small enough to prevent rainwater from entering the ventilation system. The hat is designed to rotate with the action of the wind. The stronger the wind blows, the more the slats rotate and the stronger the air supply from the inside to the outside.
