Features, Basic Information<br />
<strong>Air</strong> <strong>Atomizing</strong> <strong>Nozzles</strong><br />
<strong>Spray</strong> Set-up Features<br />
• Each series is available with a pressure spray set-up or siphon<br />
spray set-up.<br />
• Each set-up provides a specific spray pattern with a specific<br />
capacity and spray coverage range performance.<br />
• <strong>Spray</strong> set-ups are interchangeable for each nozzle series.<br />
– Round spray: Extended full cone round spray pattern.<br />
– Wide angle round spray: Hollow cone-type, wide angle round<br />
spray pattern.<br />
– 360° circular spray: Hollow cone-type 360° circular spray pattern.<br />
– Flat spray: Extended flat or sheet-type spray pattern.<br />
– Deflected flat spray: Extended flat or sheet-type spray diverted<br />
away from the axis of the inlet connection.<br />
• Each spray set-up consists of an air cap and fluid cap.<br />

Atomization <strong>Co</strong>ntrol Features<br />
• Achieved by adjusting the air and liquid pressure in the spray<br />
set-up.<br />
• Obtaining finer atomization is accomplished by increasing the<br />
air pressure and/or lowering the liquid pressure, resulting in a<br />
high ratio of air flow rate to liquid flow rate.<br />

Fluid cap<br />
Internal Mix Features<br />
• Liquid and air are mixed internally to produce a completely<br />
atomized spray.<br />
• Liquid and gas streams are not independent and a change in air<br />
flow will affect the liquid flow.<br />
• Internal mix uses pressure set-ups and is available with the<br />
following spray patterns:<br />
– 360° circular spray.<br />
– Deflected flat spray.<br />
– Elliptical spray.<br />
– Flat spray.<br />
– Round spray.<br />
– Wide angle round spray.<br />
External Mix Features<br />
• Liquid and air streams are mixed outside of the nozzle.<br />
• <strong>Air</strong> and liquid flow can be controlled independently.<br />
• Effective for higher viscosity liquids and abrasive suspensions.<br />
• External mix can use siphon set-ups or pressure set-ups.<br />
• When a siphon set-up is used, a round spray pattern is produced.<br />
• When a pressure set-up is used, a flat spray pattern is produced.<br />
