A reuseable panel for equalizing pressure between adjacent compartments includes a frame and a movable floor which is releasably sandwiched within the frame on three sides. When there is a sufficiently large pressure differential between the compartments, the three sides of the door are dislodged from the frame (blowout) thereby exposing an opening to allow the pressure between the compartments to equalize. In order to provide additional control over the pressure at which door blowout occurs, one end of a flexible strap is fixedly attached to the door while the other end is removably connected to an attachment bracket which is fixed to the frame. By adjusting (i) the configuration of the attachment bracket, (ii) the depth at which the door is sandwiched within the frame, (iii) the number of attachment brackets, (iv) the position of the attachment brackets, and (v) the side of the frame on which the attachment brackets are mounted, the pressure differential at which door blowout occurs can be adjusted.

Apparatus for equalizing a pressure differential between first and second bodies, the apparatus comprising: a. a movable door; b. means for supporting the movable door, the supporting means (i) being connected between the first and second bodies to maintain the pressure differential therebetween and having an opening which communicates between the first and second bodies, (ii) supporting the door in a manner that the door moves between a first position covering the opening so as to maintain the pressure differential and a second position not covering the opening so as to reduce the pressure differential, the supporting means further including a frame having first and second frame portions which releasably engage the movable door therebetween in the first position and in a manner that when a selected pressure is reached, the movable door is dislodged from between the first and second frame portions by the force of the pressure differential; and c. attachment and release means, having a first part which is attached to the door and a second part which is attached to the supporting means, for maintaining the door in the first position until reaching the selected pressure differential, and for releasing the door to the second position when the selected pressure differential is reached.
