Stainless Steel Turbine Ventilator

Our non-powered roof turbine ventilator is an energy-free ventilation solution for industrial buildings. Constructed from 304 or 201 stainless steel, it delivers outstanding weatherproof and anti-rust performance to withstand rain, wind and outdoor temperature changes.
It operates purely by natural wind pressure and thermal buoyancy, no electricity required, helping remove accumulated hot air, humid air, smoke and peculiar smells continuously. The rotating turbine design creates stable negative pressure inside the building, improving indoor air circulation efficiently.
Simple to install on roof tops, low maintenance and no operating cost. Widely applied in workshops, warehouses, barns and factories. We support material selection between 201 and 304 stainless steel to fit different budget and corrosion resistance needs.
