• Large turn-down ratio.
• Spray angle of 20゚ or 60゚.

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

Applications

Product specifications

Structure • Comprising several parts: Spray tip, whirler, adaptor, outer pipe (for air), inner pipe (for liquid), etc.
• Internal mixing type designed to mix compressed air and liquid inside the nozzle (Outer air type: Liquid flows in the center of the nozzle, while compressed air flows along its circumference).
• Liquid pressure type.
Material Stainless steel 316L, 304 etc. (For details, see the component list below the drawing)
