Tornado Turbine

Natural Roof Ventilators

The Ventrite Tornado Series of Roof Ventilators are South African designed and manufactured. This cost-effective and efficient ventilation system is ideal to ventilate factories, workshops, warehouses, agricultural applications, schools, hostels, change houses, assembly halls and other building structures which require effective ventilation. The positive extraction of the Tornado Turbine ventilators eliminate dust penetration and a down-draught into the building to ensure a cleaner and heal-their working environment.

Benefits And Features

Dynamics Of Products


Superiority Of Products

The design of the Tornado enables the ventilator to be activated by natural convection from inside the building and also allows it to be assisted by the wind outside. Wind creates a flow of air through the throat of the Tornado to enhance extraction. Users of Tornado Turbines continually report reduced stress and increased productivity due to a healthier working environment.

The whirling turbine action removes convected heat and polution build-up
