MEDIA/AQUA BLASTING

With wheel blasting, electric motor energy is converted directly into abrasive kinetic energy via the rotation of a turbine wheel. With air blasting however, the blast media will be pneumatically accelerated via compressed air, which is then projected, at force, out of nozzles and directly onto the components needing to be cleaned/prepped.
