The AutoJet® Model 1550 Modular Spray System ensures accurate, precise placement of the liquid being sprayed to minimize waste. The system provides automatic on/off control of electrically- and pneumatically-actuated spray nozzles and offers greater precision than manual operation or devices such as solenoid valves. Proper flow and drop size eliminates quality control problems due to uneven application and improves worker safety by minimizing misting and overspray. Accurate spray placement on the target reduces the use of costly chemicals and coatings and reduces mess and maintenance time. The system is self-contained and compact.
