A dust-collecting apparatus is described that includes a lift-off door assembly that provides access to the interior of the dust-collecting apparatus while minimizing the adverse effects on the normal operation of the apparatus by maintaining a proper seal between the interior and the exterior of the apparatus. In particular, the lift-off door assembly includes a top plate, a door frame, and a bottom plate. The top plate is secured to the door frame. Lift clips are provided about a perimeter of the bottom plate and are secured to the bottom plate. Lifting ends of the lift clips are positioned over an outer portion of the door frame, such that when a lifting force is applied to the top plate, the top plate, door frame, and bottom plate are lifted together via the lift clips to move the lift-off door assembly from the closed position to the open position.
