F4-VB Controlled Atmosphere Spray Gun

F4-VB Controlled Atmosphere Spray Gun

The F4-VB heavy-duty plasma spray gun applies coatings in a controlled atmosphere, in a process called Vacuum Plasma Spraying (VPS). The vacuum chamber contains an inert atmosphere without any active residual gasses, thus coatings produced in this system are oxide-free.

Typical applications include coating parts for:

  • Turbine manufacturing
  • Chemical processing
  • Medical industry

Key characteristics

  • Specially designed nozzle attachment provides concentrated plasma jet characteristics
  • Powder injection before plasma jet exits nozzle
  • High powder particle velocity results in dense coatings
  • Ideal for Thermal Barrier Coatings (TBC) in the turbine industry
  • Higher energy levels enables coating of hard materials



Maximum power

55 kW

Process gasses

Argon, Helium, Hydrogen, Nitrogen

Controller compatibility

MultiCoat™, ChamPro™
