Abstract
A door system has a compartment formed with a first gateway and a second gateway opposed to the first gateway, and a barrier apparatus housed in the compartment. The barrier apparatus includes a swivel panel which swings back and forth between a first position where one surface of the swivel panel faces the first gateway, and a second position where the opposite surface of the swivel panel faces the first gateway. The barrier apparatus further includes a pair of door panels provided at the opposite ends of the swivel panel to move with the swivel panel. The door panels synchronously open the gateways when the swivel panel is at the first position and at the second position. Air sealing is provided between the compartment and the door panels.
