ABSTRACT:
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.
