  • Rotating nozzles for 2-Dimensional and 3-Dimensional cleaning.
  • Rotation is driven solely by the spray reaction force.
  • All supplied water is used as driving force and cleaning water. Minimal energy loss.
  • Nozzle mounts are available in two arms or four arms.

[JA-3: 3-Dimensional type]

  • Available in low-pressure specification (0.3–1.2 MPa, ca. 3 – 12 bar, max. 6.0 MPa, ca. 60 bar) or medium-pressure specification (1.0–3.0 MPa, ca. 10 – 30 bar, max. 15.0 MPa, ca. 150 bar).
  • Low-pressure type is for cleaning by the force of spray flow volume, and medium-pressure type for cleaning by the force of spray pressure.

[JA-2: 2-Dimensional type]

  • You can select suitable nozzles depending on your purpose and application; solid stream jets for powerful cleaning, flat spray nozzles with wide spray coverage, and more.
  • Rotation is driven not only by water, but also by air. Ideal for blow-off drying, air blowing especially for complex applications.
  • In addition to the standard arm length (200 or 300 mm), shorter or longer arms suitable for a target area can be prepared within 200–1500 mm.


  • Spray capacity of JA-3 (3-Dimensional type)
    Low-pressure type (JA3-2L): 24–82 ℓ/min at 0.3–1.2 MPa (ca. 3 – 12 bar)
    Medium-pressure type (JA3-2S/4S): 12–70 ℓ/min at 1.0–3.0 MPa (ca. 10 -30 bar)
  • Spray capacity of JA-2 (2-Dimensional type): 14–98 ℓ/min at 0.3 MPa (ca. 3 bar)


  • Cleaning of tanks, containers, conveyors, etc.
