Clog-resistant wide-angle flat spray fine fog

YYA series

YYA series


The YYA series nozzles’ features:

  • Wide-angle flat spray pneumatic nozzle producing fine atomization with a mean droplet diameter of 15 – 30 μm (*2).
  • Combines “clog-resistant” and “wide spray angle” features.
  • Compact, 22 mm-long design.
  • Capable of spraying viscous liquid up to approx. 300 cP. (*3)

*1) Measured at compressed air pressure of 0.3 MPa (ca. 3 bar) and liquid pressure of 0.05 MPa (ca. 0.5 bar).
*2) Measured by Laser Doppler Method.
*3) Spray capacity and spray angle are reduced when viscous liquid is sprayed.
Raising the liquid pressure to 0.2–0.3 MPa (ca. 2 bar – 3 bar) is recommended when spray capacity is small, otherwise the spray pattern becomes irregular.
