IKEUCHI DOVVA-G series nozzles

Flat Spray Semi-Fine Fog Nozzles

Features

• Flat spray pneumatic nozzle producing semi-fine atomization with a mean droplet diameter of 80 μm or more (*3).
• Clog-resistant design due to large free passage diameter is suitable for spraying factory effluents and waste water.
• Simple structure, easy maintenance.

*1) Measured at compressed air pressure of 0.1-0.4 MPa and liquid pressure of 0.1-0.5 MPa.
*2) Free passage diameter of spray orifice for DOVVA-G 70ﾟ spray angle type.
*3) Measured by Laser Doppler Method.

Applications
