Pneumatic Slit Laminar Spray PSN series nozzles

Thread standard - Pipe conn. size 3/8F Standard pressure -
Spray angle - Spray capacity 8.0–28.0 ℓ/min (*1) Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter - Air consumption 520–1,700 ℓ/min, Normal (*1)
Air pressure - Free passage diameter -


• Pneumatic slit-laminar nozzle with uniform spray distribution throughout the entire spray pattern area.
• While multiple-nozzle alignment of conventional pneumatic spray nozzles leaves some spots unwashed, PSN nozzles provide uniform spray distribution and achieve a complete cleaning, leaving no spot unwashed. PSN can be used at a short distance.

*1) Measured at compressed air pressure of 0.1–0.4 MPa and liquid pressure of 0.1–0.4 MPa for PSN nozzle with slit length of 1000 mm and slit opening of 0.05 mm.


Cleaning: Glass substrate, liquid crystal
Cooling: Steel plates, moldings
Moisture control: Paper, cardboard

[Steelmaking industry]
Surface finish process: Precision cleaning for steel surface treatment, Roll cleaning

Industries in which this nozzle is used

Electronics, Automotives, Steelmaking
