Modern Technology for Flawless Clearcoat and Basecoat Performance

The all-new WS-400 Series 2 OBS (Optimum Basecoat Settings) spray gun is engineered specifically for compliant basecoat applications. Featuring re-engineered air caps and fluid nozzles, it delivers exceptional out-of-the-box performance, offering refinishers consistent, high-quality results with fewer common issues.

Advanced Split Nozzle™ 2.0 Technology

Enjoy flawless atomisation with every spray. The Split Nozzle™ 2.0 system creates ultra-fine, uniform droplets that reduce clearcoat problems like popping, overload, and solvent boils. Whether painting vertical or horizontal panels, the WS-400 delivers a smooth, even wet-out—minimizing runs, sags, and costly rework.

Benefits include:

  • Fewer passes per panel

  • Lower paint consumption

  • Faster application times

  • Reduced material costs

Tested extensively, the Series 2 ranks among the most economical and reliable spray guns available today.
