Description

Swirl-Air™ Concentric Inline Air Atomizing Nozzle produces a hollow cone spray pattern using a two-fluid air atomization design. Available with flow rates from 0.2 to 40 GPM and spray angles from 30° to 120°, the nozzle is suitable for applications requiring fine atomization, broad operating flexibility, and reliable spray performance. The inline configuration provides unobstructed spray coverage while maintaining the atomization efficiency and durability of the Swirl-Air™ nozzle range. Available in Stainless Steel 316L/310, 440 HSS, Hastelloy®, Inconel®, and Titanium.

Spray Characteristics:
Produces a hollow cone spray pattern. Multi-purpose design suitable for a wide range of atomization applications. Available spray angles from 30° to 120° depending on nozzle configuration. Designed to provide efficient air atomization over a broad flow range from 0.2 to 40 GPM.
Construction and Materials:
Two-piece construction consisting of a nozzle body and an integral deflector ring and cap that can be removed without disturbing pipe connections. No external struts or supports interfere with the spray pattern. Standard configurations are available in 316L Stainless Steel and 440 HSS, with Hastelloy® C276, Inconel® 600, and Titanium available for demanding applications. Various lance configurations are available to suit installation requirements.
