  • Full cone spray pneumatic nozzle producing a large volume of semi-fine to semi-coarse atomization with a mean droplet diameter of 130 μm or more (*3).
  • Large turn-down ratio. Uniform spray droplet size distribution across the entire spray area.
  • Clog-resistant design due to large free passage diameter is suitable for spraying factory effluents and waste water.
  • Simple structure, easy maintenance.

*1) Measured at compressed air pressure of 0.2-0.4 MPa (ca. 2 – 4 bar) and liquid pressure of 0.05-0.7 MPa (ca. 0.5 bar – 7 bar).
*2) Free passage diameter of nozzle orifice.
*3) Measured by the immersion sampling method.


  • Cooling: Gas, moldings
  • Combustion: Waste water
