Improve airflow, reduce heat and remove stale air with wind-driven rotary ventilators designed for residential, commercial and industrial buildings.
Rotary roof ventilators provide a simple, effective way to improve airflow within a building — without relying on powered systems. By harnessing the natural movement of wind and thermal air currents, these systems continuously extract hot, stale and moisture-laden air from the building, replacing it with cooler, fresh air from outside.
This creates a more comfortable, healthier indoor environment while helping to reduce heat build-up, condensation and reliance on mechanical ventilation.
Each system is designed to suit different building types — from residential roof spaces through to large-scale industrial environments.

For residential applications, rotary ventilators help regulate temperature and moisture within the roof space.
During summer, hot air is expelled before it can transfer into living areas. In winter, moisture is removed, reducing the risk of condensation, mould and damp insulation.
Typical sizing is based on roof area, with guidelines such as:
In commercial and industrial environments, effective ventilation is essential for maintaining air quality, managing heat and improving working conditions.
Rotary ventilators provide a reliable, low-maintenance solution. Removing hot air, smoke, fumes and stale air while supporting a continuous flow of fresh air throughout the building.
Systems are available in multiple sizes and configurations to suit different building volumes and performance requirements, with larger units delivering significantly higher air extraction capacity. Because every building performs differently, correct sizing and placement are critical. Roofing Industries can assist with calculations and system recommendations to ensure optimal performance.
