ABSTRACT An air flow control system suitable for use in combination with an air conditioning system such as a centralized air handling system,or the cooling system of a stand-by generator,uses an air flow control device to effect simultaneous changes in the flow paths of fresh air entering, exhaust-air leaving and mixed air-flow entering into the system, in self-balancing relation such that a full air-flow range of system utilization is made available without at any time incurring the risk of system over-pressurization. The range of system operation extends from one hundred percent system air recirculation to one hundred per-cent fresh air supply, The air flow control device generally has a ratio of deflector axial length to width greater than unity. In one embodiment a pivotal deflector means incorporates an inclined deflector plate. In another embodiment a fixed baffle is used in co-operation with the movable vane of the device.
