Pinnacle Roof Turbines


Pinnacle rooftop turbines deliver natural, no-cost climate control. Optimize production and performance with green, wind-driven roof ventilation.

A cool, comfortable working environment promotes higher production levels, and optimum air quality is important to inspire top performance from your personnel. Our precision engineered Pinnacle Turbines, and a gentle breeze is all you need to step up your operations.

Tap into natural ventilation:


Why consume electricity when you can tap into the power of natural ventilation? Our roof-mounted Pinnacle Turbines have fins that catch the wind. Thus, avoiding any unnecessary operating costs.


Optimize indoor air quality with natural extraction:


When the Pinnacle turbine ventilators draw out stale interior air – as they spin, they create a natural vortex that extracts heated, stale air from within your building and they extract unhealthy particulates, moisture, and toxins that degrade indoor air quality and dispel it outdoors.


Made in South Africa with guaranteed quality:


We make our Pinnacle turbine ventilators from high quality yet lightweight materials right here in South Africa. We are so confident in their quality and durability that we back them with a 5-year guarantee.

How Turbines Work

How Pinnacle Turbines work:

Pinnacle Turbines provides natural ventilation by replacing hot, stale air inside buildings with clean, fresh air from outside.  

The mechanics of the system are simple: The heads of the ventilators contain fins, which catch the wind as it blows. The turbine head starts spinning when heat is extracted through the turbine throat. The spinning turbine head, assisted by the wind, creates an extraction vortex below that will remove hot stale air from the building. Cool fresh air is then replaced through louvres and other openings at low level, vastly improving indoor air quality.  

The continuous natural ventilation capabilities of the system vastly improve indoor air quality and ensure air inside the building is always fresh and clean. The system runs continually and has the capacity to remove vast amounts of air from indoor spaces.
