Wind-Driven Roof Ventilators — No Electricity
These work by wind spinning the turbine, creating a low-pressure zone to draw out hot/stale air naturally.
🛠️ How They Work
Turbo/air ventilators:
- Spin with wind or convection to create a low-pressure area.
- Draw out hot, moist, or polluted air from inside a structure.
- Allow fresh air in through other openings, enhancing ventilation without power.
📌 Common Uses
These ventilators are widely used on roofs of:
- Industrial sheds and warehouses
- Workshops and garages
- Residential buildings
- Greenhouses and storage areas
They help reduce indoor heat, humidity and improve air quality while being energy-free and low-maintenance.
