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™
