ROOFVENT is a natural air ventilation system. it is a free spinning roof ventilator which works by utilizing the velocity energy of the wind to induce air flow by centrifugal action. the centrifugal force caused by the spinning vanes creates a region of low pressure area which draws and throws out air from below and causes fresh cool air from the outside to come in. The slightest breeze will cause the ECOROOFVENT to spin. even after the breeze has stopped, the fly wheel effect of the rotor cage will use its stored energy to continuously remove stale air, gases, fumes and smoke giving rise to ventilation. suction is maintained even at low wind velocity. convective thermal currents are given boost by venture dome to further enhance the rotation of the ROOFVENT. cooler air from outside will rush into the negative space within the building in order to maintain a condition of equilibrium.
