• Advantage: Stainless steel offers excellent corrosion resistance, high strength, heat resistance, and decorative appeal, making it durable. The roof vent features double, tightly spaced blades that provide high airflow and rain protection. It efficiently exhausts stale indoor air while preventing rainwater from entering the ventilation system.
• Instruction: Install the Stainless Steel Roof Wind Turbine Cap Vent on the roof in a location that allows for optimal airflow. Then ensure that the vent is securely fastened to the roof to prevent any leaks. And the rotating roof vent will automatically utilize the temperature difference between indoor and outdoor air to create convection and exhaust stale air.
• Application: This is an unpowered exhaust system with a spherical blade design that is suitable for industrial buildings, factories, workshops, livestock farms, and etc. The product principle utilizes the temperature difference between indoor and outdoor air to create convection, driving the turbine to rotate. The negative pressure effect of centrifugal force is then used to exhaust stale indoor air. It is easy to install and requires no external power source.
• NOTE: Ensure proper installation to prevent leaks and ensure efficient operation. Also, regularly inspect the vent for any debris or obstructions that may affect airflow.
