Industrial Grade Roof Ventilation System utilises the velocity energy of the wind to induce flow of air by centrifugal action. The Roof Ventilation System creates a region of low pressure area which draws and throws out hot air from below and fresh cool breeze is pushed in. The Roof Ventilation System provides a cooler, damp free and low humidity working environment. Industrial Grade Roof Ventilation System is available in aluminium finish and can be fitted to any type of roofing.
