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

Thread standard - Pipe conn. size Air inlet: 3/8F–3/4F, Liquid inlet: 1/4F–3/8F Standard pressure -
Spray angle - Spray capacity 50–1,600 ℓ/hr (*1) Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter - Air consumption 1,430–5,800 ℓ/min, Normal (*2)
Air pressure - Free passage diameter 2.0–4.3 mm (*3)


• Full cone pneumatic spray nozzle producing a large amount of 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.

*1) Measured at compressed air pressure of 0.3–0.4 MPa and liquid pressure of 0.02–0.2 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, etc.
• 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 outside the nozzle for atomizing (External 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.
