Shiv Industries is the trusted manufacturer and exporter of Wind Driven Turbo Ventilators, which are widely demanded by those industries, emitting excessive heat can damage roof sheathing, felt and composition shingles. Our Wind Driven Turbo Ventilators help to ventilate hot emission and replace it with the fresh air from outer, there by preserving the life of the roof.

Engineered to exhaust Industrial pollutants such as

• Smoke
• Dust
• Poisonous gases
• Humidity
• Fumes
• Heat
• Invisible irritants

Specifications

• Designed to withstand winds in excess of 140 Km / hr
• Exhausts hot air due to stack effect even when there is no wind
• Smooth and quiet operation

Functioning

• Takes advantage of the wind to create a positive flow through the throat of the ventilator
• Wind influences the performance of the ventilator in two ways:
  
• First, wind approaches and strikes the ventilator, creating an area of low pressure on the leeward side of the turbine
• Low pressure zone is fed by drawing air from the turbine
• Causing a continuous extraction of air from the building
• Secondly, by turbine rotating, the centripetal forces associated with the rotation fling air outwards form the tips of the vanes
• Air is drawn into the throat of the ventilator from the building causing continuous ventilation
• Turbine will even rotate and exhaust in the absence of wind using the thermal currents developed within the building
