Features
• Thick flat spray pneumatic nozzle producing a large volume of semi-fine atomization with a mean droplet diameter of 50 μm or more (*3).
• Liquid pressure type under the liquid pressures of 0.07–0.7 MPa.
• Large turn-down ratio with minimal variation in spray angle.
• Uniform distribution suitable for multiple-nozzle arrangements.
• Thicker flat spray pattern covers wider area.
• Large free passage diameter minimizes clogging.
• Spray angle of 75°, 80°, 100°, 110°, or 125°.
*1) Criteria for spray angle measurement differs depending on nozzle codes.
*2) Free passage diameter of nozzle orifice.
*3) Measured by Fraunhofer diffraction method.
