Boost Natural Airflow and Remove Excess Heat Loads

Our rotary vents are designed for easy installation on a range of different roof systems – slope, ridge, flat or curved – and can be fully customised to your project specifications and needs. This includes fire rating for smoke hazard management, fan manual operation, and bespoke bases to match building aesthetics.


With unique blade design and innovative engineering, our CSIRO-tested spinning vents only need the slightest breeze to ventilate your indoor spaces effectively.

This makes them a popular eco-friendly solution for green building projects and “whirlybird” installations.
