Eco-Friendly Air Ventilator

CHRIS Air Ventilator works by utilizing wind power induced by centrifugal action. The centrifugal force caused by rotating vanes creates law pressure which draws air out through rotating body. Amount of air drawn by ventilator is continuously replaced by fresh air from outside.
