  • Patent number: 5288324
    Abstract: A multi-color powder coat paint recovery apparatus that permits rapid color changes in a powder coat operation comprises a rotatable paint booth positioned adjacent to a painting station, with the booth having a plurality of individual paint color chambers angularly spaced around the periphery of the booth. Each chamber has an open outer side and a filter mechanism at an inner side, with the inner side being in communication with an exhaust outlet from the interior of the housing. The chamber further has primary and secondary paint hoppers positioned below each filter mechanism. An air circulating mechanism draws air inwardly from the painting station through the open outer side of the chamber, through the filter mechanism, out of the housing through the air outlet, and then returns the air through a filtered outlet in a plenum chamber behind the paint applicator. Each color chamber corresponds to a separate paint color.
