WHY

Heat and dust inside the plant —
where does it go?

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.

PRINCIPLE

Maximum load from the slightest breeze

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.

FAQ

Frequently asked questions

Does it really use no electricity?

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.

How does it differ from low-cost imports?

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.

We are not sure which size fits our roof.

Send one photo of the roof with the building use and approximate area, and we will select the model. Sloped roofs are supplied with a custom base.

Can you supply in volume for contractors?

Yes. Volume supply to contractors and mechanical installers is our main business. Send the expected quantity and we will quote a separate unit price.

Send one photo of the roof

We will come back with the model, unit price and lead time.
