Flat Spray Semi-Fine Fog NozzlesDOVVA-G series nozzles

Thread standard - Pipe conn. size 4T10 Standard pressure -
Spray angle - Spray capacity 1.0 - 25 ℓ/hr(*1) Supply air type Compressed air
Liquid feeding system Liquid pressure Mean droplet diameter - Air consumption 100 - 1,700N ℓ/min(*1)
Air pressure - Free passage diameter 2.5 - 5.9 mm(*2)

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.
