Semi-Fine, Semi-Coarse Fog Nozzles/ Full Cone Spray JJA series nozzles

Thread standard - Pipe conn. size Rc1/2 Standard pressure -
Spray angle - Spray capacity 1.1–24 ℓ/min(*1) Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter 150–650 μm (*3) Air consumption 70–720 ℓ/min, Normal (*1)
Air pressure 0.2–0.4 MPa Free passage diameter 3.7–5.2 mm (*2)


• Full cone spray pneumatic nozzle producing a large volume of semi-fine to semi-coarse atomization with a mean droplet diameter of 130 μm or more (*3).
• Large turn-down ratio. Uniform spray droplet size distribution across the entire spray area.
• Clog-resistant design due to large free passage diameter is suitable for spraying factory effluents and waste water.
• Simple structure, easy maintenance.

*1) Measured at compressed air pressure of 0.2-0.4 MPa and liquid pressure of 0.05-0.7 MPa.
*2) Free passage diameter of nozzle orifice.
*3) Measured by the immersion sampling method.


Cooling: Gas, moldings, etc.
Combustion: Waste water, etc.

Industries in which this nozzle is used

• Steelmaking
• Pollution Control
