Spinning Roof Vents & Skyaxis Wind Driven Ventilators NZ
At Roofquip, we supply Skyaxis wind-driven ventilators across NZ. Skyaxis products are ideal for whatever requirements you have. This includes extracting from your building hot and humid air, condensation, fumes, pollution, odours, stale air, and more.
The operation of our wind-driven ventilators is simple. They are fitted to your roof and are operated by the wind. This means there is no need for wires or any sort of power source. Instead, the wind operation effectively draws the hot, stale, and damp air up and out of the building.
This then brings fresh and clean air into the building from other openings such as doors and windows
As it is the wind as well as the flow of air and heat rising towards the ventilator that makes them spin, wind-driven ventilators cost nothing to run.
They are suitable for any size or type of building too, from small homes to large industrial warehouses.
Quality Skyaxis Construction
The wind-driven ventilators we supply are ideal for NZ weather conditions. Plus there is no requirement for maintenance.
All the Skyaxis ventilators we supply have a high-quality construction that uses a corrosion-resistant aluminium alloy. This makes the ventilator lightweight to ensure maximum spinning efficiency even in light wind conditions.
Skyaxis ventilators also feature self-lubricating stainless-steel axial bearings for long-lasting performance.
Not only that, we have a wide range of sizes and types available to suit the specific requirements of your building, plus the ventilator can be powder coated to match your roof’s colour.
How Skyaxis Ventilators Work:
Skyaxis ventilators work by allowing hot, stale and damp air to be drawn up and out of the building. The removal of this air creates a convection current which draws fresh air back into the building through other openings. Skyaxis ventilators begin to spin due to the heat in a building rising and also the wind running directly past the ventilator on the roof. The simple action of Skyaxis ventilators keeps energy costs down while ventilating any building, from a small home to a large warehouse – all in an eco-friendly manner.

Frequently Asked Questions
Which SkyAxis roof vent size is best for a New Zealand shed, workshop, or home?
We offer a range of sizes starting from 300mm units, which are best suited for residential homes and smaller sheds or workshops. For larger industrial workshops or commercial buildings, we recommend our 500mm, 600mm, or even 900mm ventilators for sufficient air extraction for the larger internal volume.
What’s the difference between a whirlybird roof vent and a wind-driven roof ventilator in NZ conditions?
Whirlybird is a common name for wind-driven ventilators, though Skyaxis units are engineered for superior durability and performance in the New Zealand climate. Unlike basic whirlybirds, our ventilators feature high-quality aluminium construction and stainless-steel self-lubricating bearings, ensuring silent operation and a long, maintenance-free lifespan.
Do SkyAxis spinning roof vents work well in low-wind areas of New Zealand?
Yes, Skyaxis ventilators are designed with a lightweight aluminium alloy that allows the turbine to spin effectively even in very light wind conditions. Furthermore, they utilise the “stack effect,” where rising heat from inside the building helps drive the rotation, ensuring constant ventilation even when there is no horizontal wind.
What roof types in New Zealand can SkyAxis ventilators be installed on?
Skyaxis ventilators are designed to fit most New Zealand roof profiles, including corrugated iron, long-run, and various metal tile types. Each unit comes with a variable pitch throat (up to 22 degrees) and a suitable base flashing to ensure a quick, easy, and completely waterproof installation on your specific roof.
Do you offer duct kits/ceiling diffusers for ventilating rooms in New Zealand homes?
Yes, we provide specialised duct kits and ceiling diffusers specifically for our 300mm Skyaxis ventilator model. These accessories are ideal for buildings with a ceiling cavity, allowing you to extract stale air directly from rooms beneath the roof and exhaust it outside.
