CO2 SnoGun

The CO2 SnoGun cleaning process is based on the expansion of gaseous carbon dioxide through an orifice.  This expansion leads to the creation of small dry ice particles propelled by a high velocity gas stream that is sprayed onto the parts by the CO2 SnoGun.  Upon impact with a dirty surface the dry ice media removes the unwanted particles.  When using the CO2 SnoGun, even submicron particulates and hydrocarbons are removed by this transient solvent or freeze fracture mechanism.
