  • Publication number: 20080277491
    Abstract: A powder barrier coupling for a pneumatic line of a powder spray system which is air passable but powder impassable. An exterior shell forms a passage. Disposed sealingly within the passage is a porous filter media having an average pore size and thickness which are predetermined to permit passage therethrough of air, but prevent the passage therethrough of powder of a selected average cross-sectional size.

  • Publication number: 20030046909
    Abstract: A powder paint reclamation collector includes an upper chamber for collecting powder paint particles from a paint booth and a lower chamber that receives the particles from the upper chamber. A vacuum line communicates with the lower chamber retrieving the particles from the collector and transferring the particles to a reclamation system. An air chamber receives pressurized air from an air supply and communicates with the lower chamber through a porous plate. Air bleeds through the porous plate into lower and upper chambers for fluidizing the paint particles. The porous plate and an air chamber floor angle downward from the lower chamber towards the vacuum line to improve the flow of fluidized paint particles into the vacuum line.
