A ventilator draws out harmful gas and dust to protect workers, and controls temperature and humidity to remove odour. Wherever there is a working space, it is not optional.

Our centrifugal wind-driven ventilator combines a sealed bearing with wide corrugated blades, so it turns smoothly even in a very light breeze. The rotation transfers to the built-in fixed bearing, exhausting air without wobble or noise.


From 100mm compact units to 1,500mm gravity exhausters. Choose by roof profile and required airflow.

The turbine ventilator is driven by wind and the internal updraft, so it draws no power and needs no wiring. Where heat or dust is heavy and more airflow is required, we recommend combining it with powered roof fans.
Every unit is handmade in Korea. A sealed bearing keeps it turning smoothly and quietly in the lightest breeze, and zinc and nickel plating give it a far longer service life.
