(12)-1 Fabry's ventilator (Refer to the inner view) Gas drawn in from the lower part is carried up according to the half circumference of both sides by the two rotors which turn conversely against each other, and is sent out from the outlet above. The two rotors prevent the contra flow by contacting each other in a T shape at the center. At first, one rotor's edge contacts other rotor's face, and viceversa.
