Rotating cleaning nozzles (Low and medium-pressure type) JET ATTACKER JA series

Pipe conn. size Rc1/2 Rated pressure 0.3–3.0 MPa for JA-3 (*1), 0.3-2.0 MPa for JA-2 Spray capacity 12–98 ℓ/min (*1)
Reach distance 2–9 m Cleaning distance - Max. allowable temperature 4–60℃ (40–140°F)


• 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, max. 6.0 MPa) or medium-pressure specification (1.0–3.0 MPa, max. 15.0 MPa). 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
Medium-pressure type (JA3-2S/4S): 12–70 ℓ/min at 1.0–3.0 MPa
• Spray capacity of JA-2 (2-Dimensional type): 14–98 ℓ/min at 0.3 MPa.


Cleaning of tanks, containers, conveyors, etc.
