Spray angle 90 - 115° Spray capacity 19 - 24.7 ℓ/hr, Normal Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter 430 - 488 μm Air consumption -
Air pressure 0.1 MPa Free passage diameter 2.9 - 3.4 mm(*1)


• Dual-use thick flat spray mist nozzle with uniform distribution used as a hydraulic spray nozzle and a pneumatic spray nozzle.
• Can be used as a hydraulic nozzle for medium/high flow rates and as a pneumatic nozzle for low flow rates.
(Also available as a pneumatic spray nozzle for medium/high flow rates.)
• Large turn-down ratio of 1:20.
• Suitable for processes which require minimal variation in spray distribution and spray angle.
• Even thick flat spray with a 60-degree angle yields a highly effective spray pattern for surface cooling.

*1) Free passage diameter of spray orifice.


[Steelmaking industry]
