Big Nozzle, Big Award…Again!

The year was 2016, and it was quite a time for sports fans:

  • Team USA dominated at the Summer Olympics in Rio de Janeiro. Swimmer Michael Phelps won five Gold Medals, and gymnast Simone Biles won a Gold Medal on her own, and another for the team event, contributing to the 46 total Gold Medals won by United States Olympians.
  • The Chicago Cubs and Cleveland Indians took the World Series to all seven games…and extra innings in Game Seven. That makes it hard to disparage either team, but the Cubs prevailed, winning the Fall Classic for the first time in 108 years.
  • World Series heartbreak notwithstanding, Cleveland sports fans were pretty happy a few months earlier when the Cavaliers cinched the NBA Championship in seven games, defeating the heavily favored Golden State Warriors…who beat the Cavs in both of their regular season games that year.

Another big winner (non-sports) that year was EXAIR Corporation’s Model EF5010SS External Mix Narrow Angle Flat Fan Pattern 1/2 NPT Atomizing Spray Nozzle…it won Plant Engineering’s Product of the Year Bronze Medal Award in the Fluid Handling category. Yes, there’s a Compressed Air category, and our products have won a TON of those too…as well as some other categories:

  • Material Handling (Line Vacs)
  • Maintenance Products (Super Air Nozzles)
  • Environmental Health (High Lift Reversible Drum Vac)
  • Automation & Controls (EFC Electronic Flow Control)
Just a few of our past Product of the Year award winners in categories other than “Compressed Air”.

Anyway, now it’s 2021, and the No-Drip version of that Atomizing Spray Nozzle – Model EF6010SS – has won Plant Engineering’s GOLD Medal Award in the Fluid Handling category. Model EF6010SS offers the same performance as the EF5010SS:

  • Liquid flow rates from 141 to 303 gallons per hour (tested with water)
  • Flat fan spray dimensions from 15″ wide (6″ from target) to 25″ wide (15″ from target)
  • Atomized spray at a distance of up to 35 feet away

And, of course, the No-Drip feature means you can instantly stop liquid flow by shutting off the compressed air supply, up to 180 cycles a minute, if needed. This is a great feature to have to cut down on the cost – and the MESS – associated with overspraying.

Our comprehensive line of Atomizing Spray Nozzles has options for most any liquid that can be sprayed, with a wide range of flow rates and pattern size/shapes. The 1/2 NPT External Mix Narrow Angle Flat Fan model is ideally suited for liquids with higher viscosities where a higher flow rate/thicker coating is needed, as opposed to a humidification or misting application, where a smaller Atomizing Spray Nozzle might be specified. Some current, successfully reported, applications include:

  • Snack food provider – applying flavoring to bulk snack materials.
  • Commercial bakery – spraying cooking oil onto pans used in a conveyor oven.
  • Sporting goods manufacturer – applying adhesive to the tops of skateboard decks to glue the grip tape on.

If you’d like to discuss a particular liquid spraying application, I’d love to help…give me a call.

FullStream Liquid Atomizing Nozzles

At EXAIR, we know compressed air, and we’ve been helping customers around the world get the most out of their compressed air systems since 1983. It was only logical that, about ten years ago, we got into using compressed air for liquid atomization.  If you’re looking to spray a liquid in a fine mist with a controllable pattern & flow rate, there are many advantages to using compressed air to atomize it:

  • Adjustability
  • Maximum dispersion
  • Optimal, efficient consumption
  • Small droplet size

Since their introduction, EXAIR has come to offer 142 distinct models of Air Atomizing Spray Nozzles, and, along the way, we leveraged our engineering, machining, and manufacturing prowess to gain position as an industry leader in liquid spraying.  So much so, that, earlier this year, we introduced a spraying product line that doesn’t require compressed air:  the FullStream Cone Liquid Atomizing Nozzles.  Instead of using the energy of compressed air to effect atomization, these use the energy of the liquid’s pressure and flow to change the continuous stream of liquid flow entering the nozzle into a conical spray as it exits to atmospheric pressure.  Here’s how it works:

While Air Atomizing Spray Nozzles maintain their advantage of a smaller droplet size (ours consistently make droplets under 100 microns in size,) there are clear benefits in certain applications to the FullStream Cone Liquid Atomizing Nozzles:

  • Higher liquid flow rates
  • Increased liquid coverage
  • More compact design

These are all important in applications like quenching, cooling, foam breaking, lubricating, degreasing, and sanitizing.  All stainless steel construction means they’ll stand up to a variety of chemicals…both in what’s being sprayed, and in the environment in which they’re installed.

If you have a liquid that needs sprayed, EXAIR has an engineered solution.  Call an EXAIR Application Engineer today to find out more.

No Drip, External Mix, Atomizing Spray Nozzle Overview

 

No Drip ASN
EXAIR’s No Drip, External Mix, Atomizing Spray Nozzle In Action!

EXAIR’s Atomizing Spray Nozzles are used to clean, coat, or cool parts and they also lend themselves very well to humidification and dust control.  They are constructed from rugged and durable 303 SS to provide corrosion resistance and they can operate in temperatures up to 400°F (204°C). All EXAIR Atomizing Spray Nozzles are also CE compliant.

Atomizing Nozzles are separated into 5 categories – Internal Mix, External Mix and Siphon Fed, Deflected Flat Fan, and Internal Mix 360° Hollow Circular Pattern.  They are available in 1/8″, 1/4″ & 1/2″ NPT to make it easy to provide the coverage and flow rate you need for nearly any application.  For today’s focus, we will discuss the No Drip External Mix Atomizing Nozzles.

External Mix Atomizing Nozzles have the highest flow rates and are ideally suited where precise liquid flow is required and both the air and liquid are pressurized.  Also the External Mix Atomizing Spray Nozzles can easily atomize liquids with a viscosity above 300 cP (Centipoise).

Centipoise is defined as a dynamic viscosity measurement unit. A Centipoise (cP) is a non-SI (non-System International) measurement unit of dynamic viscosity in the centimeter gram second (CGS) system of units.

Centipoise Chart

Our patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 20 PSIG for 1/8″ NPT Nozzles or 30″ PSIG for the 1/4″ or 1/2″ NPT. By incorporating this feature into the design, it eliminates the need for any additional valves or supply lines.  They are available in flow rates that range from less than 2 GPH (7.57 LPH) for our Model EF9010SS 1/8 NPT No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH (1,147 LPH) for the Model EF6010SS 1/2 NPT No Drip External Mix Narrow Angle Flat Fan Pattern.

When making a selection, below are some points to consider:

  1. Volume of liquid required?
  2. What is the viscosity of the liquid?
  3. What type of spray pattern fits the application?

If you would like to discuss External Mix No Drip Air Nozzles or any of EXAIR’s safe, quiet & efficient compressed air products, I would enjoy hearing from you…give us a call.

Atomizing Nozzles – No Drip Deflected Flat Fan and 360° Hollow Circular

EXAIR manufactures three types of Atomizing Nozzles – Internal Mix, External Mix, and Siphon Fed.  Within the Internal Mix family, there are two specialty nozzles, the Deflected Flat Fan and the 360° Hollow Circular patterns.

Internal Mix nozzles are for pressure fed applications not requiring independent air and liquid control.

The model AD2010SS is the No Drip version of the Deflected Flat Fan and is shown below. Our patented No Drip design prevents unwanted post spray drips from wasting expensive fluids or ruining product finishes. The benefit to this design is that no secondary compressed air line is necessary to activate the on/off valve for the liquid, which is the case for competitive nozzles.

Model AD2010SS – No Drip Internal Mix Deflected Flat Atomizing Nozzle

The Deflected Flat Fan patterned nozzle is designed for applications where space is a limited.  The spray pattern is at a right angle to the orientation of the nozzle, allowing the spray to be placed precisely where it is needed in tight quarters.  They are ideal for coating the insides of enclosures and ductwork.

NoDripIMDF

The model AT2010SS is the No Drip version of the 360° Hollow Circular and is shown below.

AT2010SS
AT2010SS – No Drip Internal Mix 360° Hollow Circular Atomizing Nozzle

The 360° Hollow Circular patterned nozzle is designed for applications where the spray pattern is to be orientated away form the nozzle in all directions.  They are ideal where a smooth and even coating is needed on the internal surface of a pipe or duct.  They are also good for processed where a mist is needed over a large area, including dust suppression, humidification, and cooling.

NoDripIM360HC-Pattern

The No Drip feature is a patented† design that has the added benefit of positively stopping the liquid flow when the compressed air is shut off. Post spray liquid flow can cause quality issues from unwanted drips on painted or coated surfaces.  Also, the No Drip feature helps to conserve and save on liquid use, reducing costs of expensive coatings or chemicals.

When the compressed air supply is shut off, the No Drip nozzle positively seals off the flow of liquid, eliminating over spray and drips. The design allows for just one compressed air line, there is no need for an additional to control the No Drip mechanism.

If you have questions about Atomizing Spray Nozzles, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.
