Flettner Vehicle Ventilators

Rotary Roof Vent NZ

Flettner wind-powered rotary ventilators are one of the most respected brands NZ. They are manufactured to the highest standards in the UK and are so reliable you can fit them to your vehicle and then forget about them. This is because they require no maintenance.

Flettner wind-powered ventilators require no external power source either. Plus, they are more effective than passive ventilators such as grilles or cowls.

We deliver Flettner wind-powered ventilators across NZ. Contact us today if you have a query and to place an order.

Frequently Asked Questions

The Flettner TCX-2 is our highest-performing model and is recommended for work vans that require maximum heat, fume, and moisture extraction. It is engineered to move significantly more air than standard vents and is ideal for vehicles with internal linings when used with a Slimline Base adapter.

Flettner rotary roof vents are 100% wind-driven and do not need any electrical wiring or battery power to operate. Unlike powered fans, these units provide continuous, silent ventilation without draining your vehicle’s battery or requiring complex electrical maintenance.

Yes, Flettner ventilators are specifically designed to extract stale air, dampness, and odours to prevent condensation and mould buildup. By continuously circulating the air in the cargo area, they create a healthier environment for occupants and protect tools or goods from moisture damage.

No, these ventilators are completely maintenance-free and require no electrical connection. They are manufactured using high-quality, UV-stabilised materials and sealed stainless steel bearings, ensuring they remain reliable in New Zealand’s varied weather conditions for the life of the vehicle.

We recommend the Flettner TCX-2 for larger vans and heavy-duty applications, while the Flettner 2000 is suitable for smaller vehicles. For optimal extraction, the vent should generally be positioned toward the rear of the vehicle’s roof for an effective flow of fresh air throughout the entire cargo space.

We installed two 600mm Skyaxis ventilators in our powder coating workshop. We noticed an immediate reduction in heat and fumes and It has made it a more enjoyable place to work. I climbed onto the roof to see them in action and test the air coming out. It felt like it was from a hairdryer! I couldn't believe it! I am definitely considering getting more installed in other parts of the building. I would recommend them to all. Thanks

Thought that I would just let you know that we fitted the ventilator a couple of weekends ago and wow! What a difference it made to the upstairs temperature of the house. In the past walking upstairs in summer you enter another climate zone half way up the stairs and now the temperature is only marginally higher that that downstairs. It certainly brings much needed relief from the hot weather. Many thanks

Thank you Roofquip for the support and then supply of the 7 Skyaxis roof ventilators. The team have really noticed the air temperature difference on the factory floor, the airflow is cooler and fresher and there is not the same build-up of fumes overnight when we first open up the factory in the morning. Thanks again from my team and we would be happy to recommend to anyone else.

We purchased two vents for our packing shed at the beginning of this summer and can’t believe what a difference it made to the heat. We installed these ourselves and found them really simple to install. The price was incredibly reasonable for the benefit we have received from them.
