Stainless Steel Conical Vent Cap

The conical wind hood is installed at the terminal of the exhaust system to enhance the exhaust capacity with wind pressure and prevent rain, snow, etc., from entering the duct. The pipe-shaped wind hood is suitable for natural exhaust systems. When dripping is not allowed indoors while condensation droplets may form inside the duct, a drip pan should be installed beneath the pipe-shaped wind hood, and the droplets should be led to the discharge location via pipes.

       The conical hood is composed of main components such as the upper cone cap, lower cone cap, upper umbrella cap, and lower umbrella cap.

       The cone-shaped wind hood utilizes the natural wind velocity of the environment to rotate the turbine of the windmill and the convection of indoor and outdoor air, accelerating any parallel air flow and converting it into a vertical upward flow from the bottom, thereby enhancing the indoor ventilation and air exchange. It operates without electricity, produces no noise, and can run continuously for long periods. It eliminates indoor heat, moisture, and odors, and is reasonably positioned at the top of the roof based on the natural laws of air and the principles of air flow, quickly expelling heat and polluted gases from indoors, improving the indoor environment.
