Bradford Hurricane® Natural Roof Ventilator
Bradford Hurricane is a high-performance, wind-driven roof ventilator that helps clear hot, stale and humid air from commercial and industrial buildings without using mains power. The vertical-vane turbine design extracts heat and moisture to support cooler, drier, safer interiors while reducing the load on mechanical cooling.
Built for demanding sites, Hurricane pairs robust aluminium construction with a lightweight form that's easy to install on new builds or retrofits. Finish and variant options suit coastal and corrosive environments, bushfire-prone areas and high temperature applications, giving specifiers a reliable, low-energy way to improve air movement at scale.
Features and Benefits
Bradford Hurricane promotes continuous airflow through large volumes, helping to lower internal heat build-up, reduce condensation and improve air quality for occupants. The wind-powered design means no running costs, and the low mass and variable-pitch bases simplify installation across common roof slopes. With durable materials, tested performance and optional dampers and bases, Hurricane delivers dependable, low-maintenance ventilation that can also reduce HVAC energy use and total cost of ownership over time.
