Abstract:

An air ventilation system. The system may comprise an air flow control box and a control module, wherein the air flow control box may comprise: a damper housing, ventilation cap, damper assembly, control arms, and damper motor. The damper housing may define a passage traversing from a proximal end to a distal end of the damper housing and may comprise a ventilation opening. The ventilation cap may be hingedly connected to the damper housing for selective movement between an open position and a closed position. The damper assembly may be in covering relation with the passage and may comprise damper blades that pivot together for selective movement between an open position and a closed position. The damper motor may actuate the selective movement of the ventilation cap and the plurality of damper blades via the control arms. The control module may actuate the damper motor of the air flow control box.
