Ultra-Low Pressure Semi-Fine Fog Nozzles/ Full Cone Spray LSIM series nozzles

Thread standard - Pipe conn. size Liquid inlet: 1/2F, Air inlet: 1*1/2M or 2M Standard pressure -
Spray angle 20° Spray capacity 0–1,000 ℓ/hr (*1) Supply air type Blower air
Liquid feeding system Liquid pressure Mean droplet diameter - Air consumption 1,500–6,000 ℓ/min, Normal (*2)
Air pressure 0.02–0.06 MPa Free passage diameter 1.5–2.0 mm (*3)


• Full cone spray pneumatic nozzle producing fine atomization with a mean droplet diameter of 40 μm or more (*4).
• Produces semi-fine atomization having no large droplets. When the mean droplet diameter is 80 μm, the maximum droplet diameter is 180 μm (*4) under air-water ratio of 250.
• Energy-saving for blower-use. Low running cost.
• Spray angle of 20゚.

*1) Spray capacity measured at liquid pressure of 0–2 MPa.
*2) Air consumption measured at compressed air pressure of 0.02–0.06 MPa.
*3) Free passage diameter of liquid inlet.
*4) Measured by Laser Doppler Method.

Product specifications

Structure • Comprising several parts: Nozzle tip, adaptor, pipe, etc.
• Internal mixing type designed to mix compressed air and liquid inside the nozzle (Outer air type: Liquid flows in the center of the nozzle, while compressed air flows along its circumference).
• Liquid pressure type (utilizing blower air for atomizing).
Material Stainless steel 316L, 304, etc. (For details, see the component list below the drawing)
