Medium Capacity Impinging-type Fine Fog Nozzles/ Full Cone Spray AKIJet® series nozzles

Thread standard - Pipe conn. size Air inlet: 1/4F–3/8F, Liquid inlet: 1/8F–1/4F Standard pressure -
Spray angle - Spray capacity 10–450 ℓ/hr (*1) Supply air type Compressed air
Liquid feeding system Liquid pressure, Liquid siphon Mean droplet diameter - Air consumption 340–1,800 ℓ/min, Normal (*2)
Air pressure - Free passage diameter 0.6–1.1 mm (*3)


• Full cone spray pneumatic nozzle producing fine and semi-fine atomization.
• Atomized droplets are impinged against each other creating ultrasonic waves, which results in creation of a uniform distribution of even finer droplet sizes.
• Liquid siphon feed type (liquid pressure device is not required). Use with the liquid pressure device is also possible.

*1) Measured at compressed air pressure of 0.3–0.4 MPa and liquid pressure of 0–0.25 MPa.
*2) Measured at compressed air pressure of 0.3–0.4 MPa.
*3) Free passage diameter of liquid inlet.


• Cooling: Gas, steel plates, refractories, moldings, glass
• Moisture control: Flue gas, concrete
• Combustion: Oil, waste water
• Others: Mixing two liquids, Spray drying

Industries in which this nozzle is used

Steelmaking, Pollution Control, Paper & Pulp, Printing, Automotives

Product specifications

Structure • Comprising several parts: Nozzle body, adaptor, strainer, etc.
• First compressed air and liquid are mixed inside the nozzle for atomizing (Internal mixing type). Then air-stream entraining fine fog jets out from the nozzle and impinges against another air-stream of the same nature for shattering the fog into even finer, more-uniform droplets.
• Liquid pressure type or Liquid siphon feed type.
