  • OPTISTAR’s patented Digital Valve Control, (DVC) offers a new standard of precision and more uniform film thickness, resulting in lower operating costs
  • Within the OPTISTAR, the DVC automatically adjusts all air required for powder coating, ensuring air flow accuracy to plus or minus 1%..
  • Uniform volume control and industry-leading first-pass transfer efficiency saves powder, and results in a more consistent finish.
  • Unmatched program storage capacity (up to 250) allows for fast recall of all settings for any application.
  • Unprecedented control over voltage, current, electrode rinsing air, powder output, and air volume give you the ability to repeat quality performance–every time.
  • Remote gun triggering and purging can be operated from the Programmable Logic Controller (PLC) or canbus serial protocol.
  • OptiStar communicates with your PLC, allowing for advanced diagnostics and programmability.
  • Optional Flow-Control Module™ for closed-loop control of the total air volume for consistent powder delivery and accuracy.
  • Rinse air selection buttons ensure correct air volume, keeping the electrode clean, and maximizing transfer efficiency.
  • Help code display simplifies operator troubleshooting.


  • Advanced engineering of OPTIFLOW™ High Performance Powder Pump ensures uniform powder delivery for every application.
  • Keyed quick disconnects facilitate fast installation and removal.
  • Only one major wear part keeps spare parts and operational costs exceptionally low.
  • Check valves and plug-in design promote reliability and easy maintenance.
  • Precision-manufactured injector jet stays in place, assuring proper flow every time.
