Downward spraying petcock nozzles above each sink deliver liquid solvents for rinsing and nitrogen/air for drying. The nozzles extend outward for extra clearance and point down to facilitate cleaning procedures.
Gauges and knobs on the rear allow pressure control of air and solvent lines. Quick-connect fittings on the other side feed each line. Additional service lines can be installed. Plumbing is also available in other materials, including Teflon and polypropylene.
