Abstract:

A spray applicator system is provided with a reservoir manifold assembly having a separate reservoir for each different coating to be applied. Reservoirs are filled from a coating supply system and isolated electrically from the supply system when coating is dispensed from a reservoir to the applicator. Multiple sets of reservoirs can be used, so that an empty reservoir in one set can be filled while coating is dispensed from a reservoir in the other set. The set of reservoirs in which a reservoir is being filled is isolated electrically from the applicator, and of the set of reservoirs in which a reservoir is dispensing coating to the applicator is isolated electrically from the supply system.
