Edmonds Hurricanes

Hurricane Natural Vertical Vane Ventilation

For over 25 years, the Hurricane® range of vertical vane natural ventilation technology has been built to endure the tough conditions and operating environments. Edmonds ventilation products are designed, engineered and manufactured at its ISO9001 accredited facility in Seven Hills, Australia.

Hurricane was the original industrial ventilator to incorporate Edmond's patented vertical vane technology.


Edmonds designed a heavy duty bearing system to improve ventilator performance and durability in high wind speeds. This bearing system prevents ingress of fine dust particles and fumes from harsh environmental conditions.


Good air circulation promotes the exhaust of hot and stale air and can prevent humidity build up. A well designed ventilator must be weather proof to prevent water ingress into the building whilst maintaining its performance. Edmonds vertical vane Hurricane range of ventilator have been performance tested to Australian Standard AS4740: Performance of Natural Ventilators to determine flow rate capacities and been wind load tested to 195km/h and tested for rain penetration to Australian Standard AS2428.1: Dynamic Wind Load & Rain Penetration Testing.


Testing at University of Technology Sydney have shown an improved co-efficient of discharge (Cd) compared to similar sized traditional spherical vents.


In addition to the improved Cd performance, vertical vane technology have distinct benefits over traditional vents as they provide:


Features and Benefits
