Pressure of the atomizing gas: The pressure of the atomizing gas determines its
volume-flow-rate and thereby its velocity in the nozzle region. The maximum gas
pressure that can be used is limited by the laboratory’s air compressor unit
(Airtower26, KAESER). The minimum gas pressure is restricted by the stability of
the spray system. Overall, the gas pressure in the ValuArc 200 spray system can be
varied between 20 psig (239 kPa) and 65 psig (550 kPa).
