External mixing type with piston

SETO-SP series

SETOJet-SP series


The SETO-SP series nozzles’ features:

  • Full cone spray pneumatic nozzle producing fine atomization with a mean droplet diameter of 60 μm or less (*1).
  • Clog-resistant design. Optimal for spraying viscous liquids.
  • No dripping from the nozzles when spray shut off.
  • Compact, 46 mm-long design.
  • By stopping the compressed air supply, controlled intermittent liquid dripping (pulse spray) is possible.
  • Liquid siphon feed type (liquid pressure device is not required). Use with the liquid pressure device is also possible.
