Sandblasting – Shotblasting

Surface treatments that project abrasive particles at high speed onto the surface to be treated. Typically used as preparation for subsequent applications of protective coatings or as a cleanup of contaminants or other residues.

The specific processes are e.g.:

  • shot blasting
  • (micro-)peening
  • bush hammering

The filtration of these processes must therefore take into account the following specific parameters:

  • abrasives and removed substances: type, hardness, grain size, impact speed
  • possible presence of contaminants: oils, fats, humidity, etc.
  • possible presence of electrostatic charges
