Abstract
A spray enclosure is provided for plural component coating application. The enclosure has a framework of four panel walls and a ceiling with a protective film cladding to altogether enclose a protected workspace. An air inlet in one wall uses a louvered grille with double-deflection louvers to deflect incoming air to the workspace. An air filter, fan and exhaust assembly is provided on an opposite wall for filtering and drawing air through the protected workspace to an exhaust. The spray enclosure is adapted for efficient laminar air flow through the protected workspace. The spray enclosure may be sold in parts as a kit.
