IKEUCHI DDA series nozzles

Oval Spray Semi-Fine Fog Nozzles

Features

• Oval 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.
• Oval spray pattern covers wide area.
• Large free passage diameter minimizes clogging.
• Spray angle is 75ﾟ, 80ﾟ, 100ﾟ, and 125ﾟ.

*1) Measurement standard for spray angle varies depending on nozzle code.
*2) Free passage diameter of spray orifice.
*3) Measured by Laser Doppler Method.

For longer lengths, please add the corresponding mass (shown below) for each 100 mm of L1 length, according to Nozzle Thread Size 1. (When the Nozzle Thread Size 1 is 1/8F, mass per 100 mm is 50 g, when 1/4F it’s 80 g, when 1/2F it’s 160 g, when 3/4F it’s 220 g)
