Abstract: A pneumatic boom system for suspending a pneumatic air hose above a ground surface so that the air hose is not in the way when not in use. The system includes an inner drum has top and bottom ends. A top disk is coupled to the top end of the inner drum and a bottom disk is coupled to the bottom end of the inner drum. The top disk defines an annular top flange extending radially outwards around the top end of the inner drum and the bottom disk defines an annular bottom flange extending radially outwards around the bottom end of the inner drum. An outer drum is disposed around the inner drum to permit free rotation of the outer drum about the inner drum. The inner drum has an exposed region defined between the top end of the inner drum and an upper end of the outer drum. The exposed region of the inner drum has an input conduit into the inner drum designed for fluidly connecting the inner drum to a supply of pressurized air.
