Manufactured in steel, Turbo ventilators are designed and engineered to exhaust pollutants from buildings. Smoke, dust, poisonous gases, humidity, fumes etc. are the main pollutants affecting the purity of air. Turbo ventilators powered by the wind are used to create effective ventilation for diverse industries. Turbine or Turbo ventilators are Round metal vents with fins which rotate even when the slightest breeze is there. Rotation causes a centrifugal force on the tip of the fins which suck out the stale hot air from inside of the building.
