<p>Automatic finish coating equipment employs a selectively variable low-pressure or "soft" air signal to control pushing of coating material through a feed tube from a coating material source to a coating material atomizing and dispensing device. This "soft air push" method maximizes the finish quality which can be achieved with coating materials having different characteristics, such as viscosities, in any operation in which frequent changes in coating material characteristics are experienced, such as, when frequent changes of coating material color are employed.</p> |
