**Principle Of Operation：the rings of this chimney cowl are specially designed and placed over the other in a way that the wind cannot go down the chinmey, thus making this cap a prefect anti downdraught solution.enough to prevent rainwater from entering the ventilation system. **Wide range of application: widely used in large-scale factories, warehouses, stadiums, livestock farms, high-rise buildings, residential buildings, etc., to effectively indoor oily , , peculiar smell, moisture, heat, and decoration Harmful gas and dust etc,Can be installed directly without complicated assembly； **Protect your chimney from rain and moisture, which is especially suitable for chimneys that are not used frequently.Stainless steel construction Thickened fixed feet; Spinner Anti-Downdraught Fits Most Standard Chimney Pots Very effective in preventing wind and increasing ventilation. **Stainless Steel Rotating Chimney Cowl Cap: Spinner Anti-Downdraught Fits Most Standard Chimney Pots Very effective in preventing wind and increasing ventilation.Rotating hood for ventilation pipes, chimneys, and air extraction.The gairing provides maximum protection without hindering the performance of the chimney. **Unpowered roof vent: The turbine fan uses the convection theory of natural wind and air to accelerate and transform parallel airflow into vertical airflow, thereby improving indoor ventilation. The hot air rises ,Hat 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 is from the inside out.
