Atomizing Nozzles: Identification and Versatility

Internal Mix Atomizing Spray Nozzles

I recently was contacted by a customer that had an application for spraying silicone.  They currently were using our Atomizing Nozzles, and they were impressed with the operation.  But they needed to change the spray pattern for a different application.  They had a variety of parts which required different spray angles and liquid amounts.  With the EXAIR Atomizing Nozzles, the air and liquid caps are interchangeable with the same body size.  So, you can change liquid flow rates, spray patterns, and even go from a pressurized liquid system to a siphon fed.  I created an informal video that shows how this can be done (click HERE).  To start, this customer did not know which model number that they were using.  So, I had to determine the size and type in order to make the proper changes. 

To do the “forensics”, we need to know a couple of things.  First, we need to find the inlet air and liquid port sizes.  EXAIR offers three sizes in NPT or BSP; 1/8”, 1/4”, and 1/2”.  Then we would need to know if it is a standard or No-Drip option.  This is easily found by looking at the top of the Atomizing Nozzle.  A standard option has the liquid stem valve that has a knurled adjustment knob; while the No-Drip option has a cylinder in place of the liquid stem valve.  From the photo below, they were using the standard option. 

AF1010SS

Since they were pumping the silicone solution to the Atomizing Nozzle, the next step was to look at the Liquid Cap and the Air Cap.  EXAIR stamps characters on each Liquid and Air Cap (reference photo below).  The Liquid Caps will only have numbers, and the Air Caps will combine letters and numbers.  From these details, I could determine that the customer was using a model AF1010SS Internal Mix Flat Fan Atomizing Nozzle. 

For their next application, they were looking to spray more of the silicone solution at a smaller target area.  I recommended the model AN1030SS.  By changing the air and liquid pressure in conjunction with adjusting the liquid stem valve, they could dial in the exact amount of silicone spray to not overuse it.  For this customer, I was able to recommended to just replace the liquid and air cap to change from the model AF1010SS to the model AN1030SS. 

If you have a liquid that you would like to spray evenly, efficiently, and effectively; EXAIR Atomizing Nozzles can do that for you.  For the customer above, they did not have to purchase new units as they could just swap out the caps to make the change.  This saved the company money and time as the bodies of the Atomizing Nozzles were already aligned to cover both parts.  If you would like know more about our Atomizing Nozzles and the features that they provide, you can contact an Application Engineer at EXAIR.  We will be happy to help.

Compressed Air in Farming and Agriculture

I used to help my father-in-law around his farm and this city boy had his eyes opened when he realized it was more than shovels, tractors and livestock. Agriculture is vital for human existence and has become far more advanced over the centuries with a continual thirst for efficiency and technology. Agriculture is just like many other industries looking for continued ways to increase yield, improve quality, maximize labor and improve technology.

EXAIR has many products used in the agriculture and food processing industries. The following details a few example by product line how we can influence efficiencies and quality of products:

Super Air Knife drying fruits and vegetables

Super Air Knives:

EXAIRs Super Air Knives are have ben used to help harvest apples and peaches. In this case they use our Super Air Knives to dry and blow off the fruit after the rinsing process just before the waxing process then again after waxing to blow off any remaining debris or moisture from the fruit before being packed.

A processing company using the Super Air Knife to clean a conveying belt equipped with a weighing system. Before the installation of the the Super Air Knife some of the cut vegetables being weighed would stick to the belt. Their solution was to clean the conveyor belt with EXAIR’s Super Air Knife to ensure continuous operation of the weighing and packaging systems.

Super Air Nozzles:

An onion farmer used EXAIR’s Model 1100 Super Air Nozzle to blow loose onion skins from the onions before packaging to improve the aesthetics to the customers.

Line Vacs:

A food packaging company repackages banana peppers from 55 gallon drums to 1 and 5 gallon containers using our Model 6066 3″ Stainless Steel Line Vac.

Using EXAIRs Model 150200 2″ Heavy Duty Line Vacs a feed stock manufacturer conveys various grains and feed stock simultaneously to a mixer which blends the ingredients. This reduced their blend time by 50%.

A grain processor used Model 142200 aluminum threaded Line Vac to convey small amounts of corn meal into a hopper which feeds into their inspection process.

A company producing worm eggs encapsulated in water soluble wax sold to farmers to enhance soil conditions. They eliminated a hand operation using Model 6081 1″ Aluminum Line Vac  to convey the worm eggs from one classifier to another.

EXAIR has several applications using Atomizing Spray nozzles to add moisture in growing environments . Greenhouses use our Atomizing spray nozzles to control humidity in the air and keep their soils moist to maintain optimal growing environments.

There are many other applications using compressed AIR on farms such as filling tires, cleaning equipment, blowing out water lines and more. Technology drives labor savings and improved quality prototypes are being designed and tested to use compressed air using drones to shoot pods filled with seeds, fertilizer and other nutrients into the soil. EXAIR will remain a strong influence in the growth of compressed air products helping to reduce the carbon footprint, enhance efficiencies and improve cost and quality within the agriculture and food processing industries.

If you have an application and you would like to talk please contact me or any of our qualified Application Engineers at 800.903.9247 and we will gladly help with our best recommendations.

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.
