ABSTRACT:
A powder spray booth (10) for spray coating articles with resinous powder is disclosed. The booth comprises a spray chamber (12) which is secured to a base portion (14). The base portion (14) comprises a clean air plenum section (36) and a trough-like oversprayed powder collection section (34) which is located directly below the spray chamber (12). Filter media (50) are secured to cantilevered filter supports (52) mounted on an interior wall of the powder collection section in fluid communication with the clean air plenum section (36) and the spray chamber (12). The spray chamber (12) is provided with front (16) and rear (20) wall panels comprising lightweight nonconductive lift-up/slide-out panels which may be easily removed to provide wide open access to the spray chamber (12), filter media (50) and collection section (34) to facilitate cleaning and reduce downtime associated with color changeovers.
