Cutting nozzle PNM 1/8'' 190-300mm

- PNM’s differ from ANM nozzles as different gas mixing criteria apply
- Two piece design consisting of a brass inner nozzle and a hollow copper outer sheath
- Turbulence must be created between the inner and outer parts of the nozzle to obtain adequate mixing of the propane and oxygen
- The volume of mixed Oxy-Propane needs to be more than double that of Oxy-Acetylene for the same useable heat
- This extra volume is achieved by very large channels that are present on the brass inner nozzle which conduct the greater volumes of gas
- PNM cutting nozzles are compatible with Type 21 torches
