Our roof turbine ventilators are engineered for optimal air exchange in various industrial and commercial settings. The ventilators operate without electricity, utilizing natural wind power and temperature differences to create efficient air circulation.
The ventilation system features scientifically calculated arc blades that maximize exhaust efficiency while preventing rainwater entry. The central axis is precision-engineered with fine steps to maintain blade integrity during high-speed operation, significantly extending the product lifespan.
Key advantages include our unique variable angle neck tube design that allows installation on roofs with slopes from 0 to 22.5 degrees. The special diversion vane of the beveled fan enhances performance while maintaining simple installation that typically takes just 30 minutes.
Applications span across power plants, chemical facilities, pharmaceutical factories, food processing plants, metallurgy operations, rubber manufacturing, warehouses, and modern civil buildings. The ventilators effectively improve indoor air quality and working environments.
Manufactured with premium stainless steel materials and imported UBC bearings from USA, each component undergoes strict quality control using professional molding tools and testing equipment before assembly. The turbine blades are designed for continuous operation for 15+ years with minimal maintenance.
