The finest, most uniform film of any application method — when finish quality is the requirement.
Air atomizing spray uses compressed air to shear a fluid stream into very small droplets, producing a softer, finer, more even film than any other method available. When the specification is a thin uniform coating, a delicate finish, or complete coverage of a contoured surface, air atomization is usually the answer.
Spraymation designs and manufactures air atomizing spray nozzles and complete systems at our facility in Fort Lauderdale, Florida — engineered around your fluid, your pattern, and your line speed rather than adapted from a catalog part.
Fluid is delivered to the nozzle at relatively low pressure. At the tip, compressed air is introduced through an air cap and shears the fluid stream apart into a fine mist, then shapes that mist into the pattern you’ve specified.
Two things follow from that. First, atomization quality is controlled by air, independently of fluid flow — so you can adjust droplet size and pattern without changing how much material you’re putting down. That independent control is the method’s defining advantage and the reason it dominates finish-critical work.
Second, all that air has to go somewhere. Air atomizing produces more airborne material than any other method, which is the tradeoff you accept in exchange for the finish. Where overspray or mist is the binding constraint, airless spray → usually wins instead.
Internal mix — fluid and air combine inside the cap. Finer atomization, best for low-viscosity fluids.
External mix — fluid and air meet outside the cap. Better for higher-viscosity or abrasive fluids, and for fluids that shouldn’t contact air until the last moment.

Where Air Atomizing Spray Is Used
[01]
Release agents and lubricants
Thin, even films where coverage matters more than film build.
Oils, glazes, and washes applied evenly across moving product.

Surfactants and web treatments
Uniform low-add-on application across wide webs.
Why Spraymation
We manufacture the nozzles.
Design, build, test, and support happen under one roof in Fort Lauderdale. If a standard air cap doesn’t produce the pattern your application needs, we engineer one that does — which is the difference between a nozzle manufacturer and a nozzle supplier.
Pattern control that holds.
Minimal variation over hundreds of continuous operating hours.
Custom engineering as standard.
Unusual fluids, awkward geometry, and low-volume applications are the work we’re built for — often the work larger manufacturers decline.
A Fortune 100 tissue manufacturer needed consistent adhesive across three application points running simultaneously at over 2,000 ft/min. Spraymation’s unified multi-station system cut adhesive consumption 40%, delivered a 99.7% tail-seal first-pass rate, and paid back in under a year.
Pre-Filled Syringe Siliconizing: Medical Device Manufacturer
A medical device manufacturer couldn’t validate its siliconization process for GMP, with coating-weight variability above 25% and recurring glide-force failures. Spraymation’s Electromatic™ 29 system cut variability to below 8% CV, reduced silicone use 35%, and reached 0.25 mg dispensing precision.
A major OSB manufacturer’s drip bars over-applied wax and fouled the blender drum, and catalog nozzles couldn’t handle the high-viscosity emulsion. Spraymation’s custom air-atomizing spray headers cut wax consumption 30%, shortened the press cycle 15%, and saved over $150,000 a year.
When should I use air atomizing instead of airless?
Choose air atomizing when finish quality, film uniformity, or fine droplet size is the requirement — it produces a better film than airless can. Choose airless → when overspray, mist, or material cost is the binding constraint, or when the fluid is too viscous to atomize well with air.
What viscosity can an air atomizing spray nozzle handle?
Generally air atomizing suits low to medium viscosity fluids; above a certain point, the air required to atomize becomes impractical and airless or extrusion is the better method. Send the fluid’s technical data sheet and we’ll confirm.
Can I control pattern width and droplet size separately?
Yes — that independent control is the primary reason to choose air atomizing. Air cap configuration sets atomization and pattern; fluid delivery sets volume.
Do you manufacture your own nozzles, or resell?
Yes — that independent control is the primary reason to choose air atomizing. Air cap configuration sets atomization and pattern; fluid delivery sets volume.
