Abstract:
1. A powder coating booth comprising: a booth canopy including a ceiling and walls constructed from electrically non-conductive materials; said ceiling including a conveyor slot that extends along the ceiling said walls having gun slots; a plurality of electrostatic powder coating guns extending through said gun slots in said walls to spray electrically charted powder coating materials onto electrically grounded work pieces conveyed through the booth by an electrically grounded conveyor which extends along said conveyor slot; a pair of electrically nonconductive, hollow air manifold members, each having an internal channel connectable to a source of pressurized air, a plurality of apertures formed in each said air manifold member and in fluid communication with a respective said internal channel to allow jets of compressed air to issue from said channels through said apertures, said air jets being directed away from said conveyor slot to blow electrically charged oversprayed powder coating material away from said conveyor slot so that said electrically charged oversprayed powder coating material is not attracted towards said electrically grounded conveyor, each of said air manifold members further having a flange to allow said manifold members to be attached to said ceiling by said flange.
