• Unpowered chimney cap: This roof turbine ventilator can work automatically, continuously and silently, without worrying about maintenance costs
• Stainless steel material: Made of thickened stainless steel, it is strong and rust-proof, suitable for harsh environments, and easy to clean
• Efficient ventilation: The rotating chimney cap can effectively prevent wind and improve ventilation, and the natural wind and air convection theory are applied to accelerate the conversion of airflow into vertical airflow to improve indoor ventilation
• Wide application scenarios: Roof vents are widely used in large factories, warehouses, stadiums, animal farms, high-rise buildings and residential buildings for ventilation
• Easy to install and use: Exhaust Cap can be installed on a slope of 0 - 22.5 degrees, with high exhaust efficiency, no noise when rotating and rainproof, preventing debris from entering
