Blasting and Spraying with Kermetico HVAF Equipment

When using a HVAF gun for grit blasting, grit particles are accelerated to extremely high velocity and simultaneously heated to over 1,200oC (2,200oF), dramatically improving cleaning and profiling efficiency of the process. Surface preparation by HVAF grit blasting increases production rate 5+ folds with reduction of grit consumption over 10-fold compared to conventional grit blasting with compressed air. Besides, the same setup is needed for blasting and coating spraying when using the same gun, what results in further cuts of time for thermal spray coating.

The standalone HVAF High-Pressure Hot Blasting Grit Feeder is designed to feed Kermetico HVAF guns with grit media.

The HVAF grit feeder includes:

  • A set of 3 m (10’) hoses/cables and 4.5 m (15’) powder hose.
  • Stand-alone manual control unit.
  • A 3.5 litres powder canister.
