Damper arrangement for a traveling spray booth

摘要

A traveling paint spray booth is movable on rails beneath a stationary exhaust duct extending longitudinally of the rails. The bottom of the stationary duct is formed by a plurality of dampers pivotable to open and closed position on a hinge having its axis extending longitudinally in the duct and protected by an air deflector. The booth is provided with damper openers which engage the body portion of successive dampers to open them as the booth passes therebeneath.
