  • Flat spray pneumatic nozzle producing fine atomization with a mean droplet diameter of 40 μm or more (*3).
  • Energy-saving for blower-use. Low running cost.
  • Clog-resistant design due to large free passage diameter.

*1) Spray angle measured at both air and liquid pressure of 0.02 MPa (ca. 0.2 bar).
*2) Free passage diameter of nozzle orifice.
*3) Measured by Laser Doppler Method.


  • Cleaning: Liquid crystal, glass substrate, printed circuit boards
  • Cooling: Steel plates
  • Dust suppression: Raw material conveyor line
  • Moisture control: Paper making
