Ceramic sandblasting nozzles (known to some as C1 Series, PB Series or Type 1 nozzles) available in various orifice sizes. These are for pressurized sandblasting units.
3/32" orifice requires 1-6 CFM
1/8" orifice requires 7-21 CFM
3/16" orifice requires 22-45 CFM
- 1/4" orifice requires 46-80 CFM
These nozzles last much longer than the smaller ceramic nozzles used on the Chinese pot blasters that are out there, as there is a lot more ceramic material that must wear away before the nozzle needs replacement.
