  • Full cone pneumatic spray nozzle producing a large amount of “fine fog”.
  • Energy-saving design – mean droplet diameter of 50 μm and a maximum droplet diameter of 150 μm (*4) at an air-water ratio of 130.
  • Large turn-down ratio.
  • Spray angle of 20° or 60°.

*1) Measured at compressed air pressure of 0.2–0.5 MPa (ca. 2 bar – 5 bar) and liquid pressure of 0.2–0.5 MPa (ca. 2 bar – 5 bar).
*2) Measured at compressed air pressure of 0.2–0.5 MPa (ca. 2 bar – 5 bar).
*3) Free passage diameter of liquid inlet for GSIMⅡ60° spray angle type.
*4) Measured by Laser Doppler Method.
