[Made-to-Order] Medium Capacity Impinging-type Fine Fog Nozzles/ Full Cone Spray AKIJet® series nozzles

Thread standard - Pipe conn. size Air inlet: Rc1/4–Rc3/8, Liquid inlet: Rc1/8–Rc1/4 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.
Material Main material: Stainless steel 303 and 316 (For details, see the component list below the drawing)
