Air Ventilator
Company: Harshad Fabricators
An air ventilator that needs no electricity is offered by Harshad Fabricators. This ventilator requires no operating cost and no maintenance. As it runs on wind energy, it is the most economical air ventilator, ideally suitable for industrial sheds, factories, hospitals, restaurants, hotels, warehouses, paint shops and even for domestic use. Materials of construction: available in aluminium and stainless steel (SS 304), with powder coating and anodising done on request. Principle: utilises wind energy to induce airflow by centrifugal action. The centrifugal force created by the rotating vanes in turn creates low pressure zone which draws fresh air from outside, thus replacing the polluted air/hot air continuously. Minimum wind pressure can spin the ventilator and even after the wind has stopped, the flywheel effect of the ventilator uses its stored energy to rotate so as to maintain fresh airflow.
