Abstract
An access door to a pressurized enclosure such as an ear corn dryer swings about an axis of rotation that divides the door into first and second panels. If the door axis of rotation is midway between the door edges, forces on the panels from the pressurized air when the door is closed are substantially equal. A person need exert only a nominal force on one of the panels to open the door. Preferably, one of the panels has a larger area than the other panel. The force produced on the larger panel keeps the access door closed such that a measurable force must be exerted by a person to open the door. The door is sealed on opposite faces when the door is closed.
