  • Hanging the bag directly from the horizontal portion or upper most portion of the stand through a hanging point 1 14 in a top portion of the bag results in a reduced overall height for the system compared to prior art systems.
  • Prior art systems hang prior art bags by a bag hanging loop 14 that extends above the top of the bag from the fill port. The hanging loop results in additional stand height required for a given bag drain point 15 height. Also, the hanging loop 14 typically hangs from a hook below an upper portion of the stand 4.
