ABSTRACT:
The device makes use of at least one plenum for each instrument, connected to the water circuit immediately upstream of the relative handpiece. Best results are obtained by connecting two such plenums to the water circuit in parallel, the one charged by the spray air circuit, the other by the power air circuit, as independent operation ensures greater reliability.
