Different Spray Patterns For Air Atomizing Spray Nozzles

Published on by Russ BowmanLeave a comment

EXAIR Atomizing Spray Nozzles use compressed air to atomize liquid flow. Across the product line, we offer a wide range of liquid flow rates. Model SF8010SS Siphon Fed Flat Fan Pattern 1/8 NPT Atomizing Spray Nozzle can get as low as 0.14 gallons per hour. That’s about a quarter of an ounce – a little less than two teaspoons – per minute. On the other end of the spectrum, Model EF5010SS External Mix Narrow Angle Flat Fan Pattern 1/2 NPT Atomizing Spray Nozzle can provide up to 303 gallons per hour of liquid flow (we tested with water; if you’re spraying something else – especially if the viscosity or specific gravity is different – your mileage may vary.) That’s about 5 gallons per minute, or approximately twice the amount of flow from a typical kitchen faucet.

Both of those Atomizing Spray Nozzles create flat fan patterns:

Flat Fan pattern Atomizing Spray Nozzles are ideal for rinsing wine bottles, spraying rust inhibitor on parts on a conveyor, or rinsing wine bottles. I know I mentioned wine bottles twice…I like wine.

Flat Fan Pattern Atomizing Spray Nozzles can generate flat fans as narrow as 3″ (at a distance of 6″ from the spray tip) or as wide as 68″ (at a distance of 15″ from the spray tip.) They’re available for Internal Mix, External Mix, or Siphon Fed operation. Most of them spray straight out from the Air Cap, as shown above, but Model AD1010SS (right) has a Deflected Fan Pattern, so it sprays at a right angle to the Spray Nozzle’s orientation. They’re particularly well-suited for installation in tight spaces or anywhere that space is at a premium.

Other applications call for round patterns. These are great for dust mitigation, humidification, applying paint or lubrication, light misting, or heavy soaking, just to name a few. They can make round patterns with diameters as small as 1.5″ (at a distance of 6″ from the spray tip) to 31″ (at a distance of 15″ from the spray tip.)

Round pattern Atomizing Spray Nozzles are popularly used for applying lubricating fluid to machine tools, flame retardant to wood trim, and color code marking on metal bars.

EXAIR also makes 360° Hollow Circular Pattern Atomizing Spray Nozzles. These are Internal Mix models, and they spray the liquid out in a fine, atomized mist in all directions. They can spray as little as 1.6 gallons per hour, or as much as 150 gallons per hour, and can create spraying diameters of up to 13 feet.

360° Hollow Circular Pattern Atomizing Spray Nozzles are great for applying a smooth, even coating to the ID of a pipe, cylinder, or duct. They can also be used for misting, humidification, and cooling of large areas.

If you need a consistent, reliable mist of atomized liquid, we’ve got you covered. To discuss an application or product selection, give me a call.

EXAIR’s New Catalog 36 Welcomes BETE

Published on by Al WooffittLeave a comment

EXAIR‘s catalog is an invaluable resource that is designed to help businesses tackle conveying, cooling, cleaning, blowoff, drying, coating and static control challenges. We are happy to announce our latest edition – Catalog 36. This catalog features an expanded selection of products, technical guides, certifications, and expert insights to help manufacturers optimize their operations.

One of the most exciting additions to this catalog is the inclusion of some (new-to-EXAIR) BETE products. BETE has been at the forefront of spray technology since 1950 and provides high-quality and durable nozzles for any spray application imaginable. EXAIR.com will now carry select models of BETE Spray Nozzles available for order in addition to EXAIR’s wide range of solutions. And just like all of EXAIR’s other stock, catalog products, every BETE nozzle featured in our catalog will be available for same-day shipping on orders received before 2:00pm ET (1:00pm ET for orders to Canada).

It goes without saying that if you would like to learn more about these impressive products, then you can read about them in our new catalog 36 (both the physical copy, or through our digital catalog on our website). But if you can’t wait until you receive yours, let me give you a quick overview of handful of them in this blog:

MicroWhirl® (MW) Series Misting & Fogging Nozzle. These come in 1/8NPT, and offer an outstanding fine mist or fog with a rugged, pinless design that ensures drip-free performance. They include a 70-micron polypropylene filter. A 200-mesh 316 Stainless Steel filter option is available as an alternative. These are great for humidification, cooling, or evaporation applications.

NF Series High-Impact Flat Fan Spray Nozzle. These come in 1/8, 1/4, and 3/8NPT. They provide a high-impact spray with evenly tapered edges, enabling effective overlapping of sprays for complete coverage. With a durable, one-piece construction and no internal parts, this nozzle is reliable and easy to maintain. The NF nozzle is the ideal solution for numerous industrial applications, including coating, conveyor cleaning and parts washing.

TF Series Full Cone Spiral Nozzle. These come in 1/4, 3/8, 1/2, 3/4 and 1NPT sizes. They are the nozzles that BETE is known for. As the original inventor of the spiral, also known as a pigtail, corkscrew, or helix nozzle. Its durable, one-piece design with no internal parts delivers clog-resistant performance and high energy efficiency. When compared to whirl-type nozzles of the same flow rate, pressure drop and angle, TF spirals produce considerably smaller droplet sizes for fine atomization.

HydroClaw® (HC) Clog-Resistant Tank Cleaning Nozzle. This FDA-compliant, clog-resistant nozzle is ideal for Clean-In-Place systems, handles particles up to 1/4″, and efficiently cleans tanks at low pressure with high flow. Designed for compact openings, the HC is offered with threaded or secure clip-on connections. Large orifices create heavy jets that disperse via deflection cups into a uniform 360° spray, ensuring complete coverage.

If you’re looking for innovative, compressed air solutions, or if you are looking for even more liquid spray nozzles, then look no further than EXAIR’s catalog 36!
