Abstract
This is a dental air and water supply apparatus for selectively and automatically controlling the supply of drive air and/or air and water coolants to any one dental drill or dental handpiece in a dental tool system. The dental apparatus includes a plurality of separately replaceable modular pneumatic circuit blocks and connecting manifolds that are fed by a master block and distribution manifold. The modular pneumatic circuit blocks are modular and separate from the distribution manifold and thereby provides easy repair of the apparatus.
