The Benefits of Air Atomizing Nozzles

No Drip Atomizing Family

With today’s pandemic, many people are finding ways to disinfect items.  I recently received a telephone call from an Original Equipment Manufacturer (OEM) that was designing a system to sanitize shopping carts.  They made a tunnel for the carts to be transferred through and to be sprayed.  They wanted to use EXAIR air Atomizing Nozzles because air atomizing nozzles can spray smaller particle sizes than pure liquid atomizing nozzles which increases the coverage area.  Thus, using less of the expensive disinfectant.

They started with a purchase of four pieces of a model SF2010SS, ¼” NPT Siphon Fed No-Drip Atomizing Nozzles for this new project.  The Siphon Fed does not require a liquid pump as it can draw the solution into the nozzle by a venturi.  The siphon height can range to 36” (91cm) below to a gravity head of 18” (46cm) above.  In some applications like this, the requirements are unknown, and for the OEM above, it was no different.

To tell you about our air Atomizing Nozzles, EXAIR offers three different body sizes in NPT or BSP conversions; 1/8”, 1/4”, and 1/2”.  We offer a standard and No-Drip option.  A standard option has a liquid stem valve that is used to manually adjusted the liquid amount; and the No-Drip option will stop liquid flow when the compressed air is turned off, and not allow the liquid to drip from the nozzle.  We have Internal Mix and External Mix for use with liquid pressures, and a Siphon Fed for open containers.  With each body style, we have a variety of liquid caps for different flow amounts, and an assortment of air caps to direct the fine mist.

With their application, they placed each nozzle inside a square frame tubing to hold them in place.  (I believe it was to protect them for being removed).  To find the best coverage, they moved the Atomizing Nozzles to different locations.  They realized that the top air Atomizing Nozzles were too far away from the sanitizing solution to use the Siphon Fed type.  So, they decided to use a liquid pump to move the disinfectant.  With the features of the air Atomizing Nozzles, we had a simple solution for them.

They wanted to change from the model SF2010SS – ¼” NPT Siphon Fed Flat Fan Atomizing Nozzle to a model AF2030SS – ¼” NPT Internal Mix Flat Fan Atomizing Nozzle.  They were looking to increase the liquid rate as well as changing to a pressurized liquid system.  (The Siphon Fed type is for non-pressurized liquid systems.)  They already had the nozzles mounted inside the tubing, so they were looking for an easy way to change the nozzles for their trial design.  With the same body size, the air and liquid caps can be interchanged relatively easy.  I have an informal video that shows how this can be done (click HERE).  By just changing the liquid and air caps, the Atomizing Nozzles were transformed to the model AF2030SS.  Look below to see how it was done with the model numbers of the air and liquid caps required.

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.

Sanitizing Applications Using Atomizing Spray Nozzles

As our journeys through the COVID-19 pandemic began, EXAIR was deemed an essential business due to our relationships with critical businesses who are also helping to fight the pandemic and keep our lives as normal as possible. Within our customer base, we are proud to include medical, food, pharmaceutical, and nearly every industry listed by the Department of Homeland Security as critical industries.

EXAIR has seen an increase in assisting end-user customers who have in house sanitizing needs and OEMs (original equipment manufacturers) who are producing sanitizing systems or “showers” for their processes and products as demanded by our pandemic circumstances.

Our Atomizing Spray Nozzles, designed to atomize fluids in a wide range of different spray patterns, utilize a small amount of compressed air that mixes with the liquid supply to create a fine mist of atomized liquid. This makes them very effective in applications that utilize expensive paints, oils, or other liquids. Rather than wasting the expensive materials, the nozzle can be set to precisely dispense only what is necessary to achieve a successful application. They are made from type 303 stainless steel.

Atomizing spray nozzles have been critical for customer’s decontamination and sanitizing needs. Most recently we learned they are being used to build an N95 mask sanitizing systems, when the customer needed to replenish their rapidly dwindling supply of atomizing spray nozzles. Don’t forget, we have them in STOCK and ready to ship!

Internal Mix Atomizing Spray Nozzles

Another customer utilizes the Model EF1010SS to perform a dry fogging process inside of residential and commercial rooms to eliminate mold, odors, and pathogens. For them this is a common process, but due to the concerns related to COVID-19 they’ve seen a dramatic increase in business related to pathogen removal. Using a two-step dry fogging process, the solution fills the entire volume of the space to remove any contaminants and prevent against microbial growth in the future. The nozzle provides a fine atomized mist that fills the entire space in a short amount of time. After a physical wipe down of all surfaces, a second solution is applied that prevents future microbial growth.

And yet another customer manufactures decontamination booths for personnel. They’re also noticing an increase in inquiries as companies look to decontaminate their employees upon entering the building. Utilizing (3) of EXAIR’s SF2020SS Atomizing Spray Nozzles, they’re able to spray a decontaminating solution to aid removal of pathogens from their clothing before it has an opportunity to spread around the office.

EXAIR Atomizing Spray Nozzles for Coating, Cleaning, Cooling

A recent customer in the automation / tool making industry had a need to spray a mold release agent onto some specialized tooling. Originally, the customer had planned to use some sort of pressurized sprayer. After some initial tests to prove the concept, the customer found that the moving mechanical parts of the sprayer became fouled by the release agent. And cleaning the internal parts was not easy to do.

In their search for a more permanent solution, the customer came across EXAIR Atomizing Nozzles. After going through some application type questions to narrow the focus down to one model, we determined that the customer would be best served by model AF1010SS (Internal Mix, Flat Fan Pattern Atomizing Nozzle). The customer had a couple of questions about the nozzle in order test the product.

  1. Is it possible to disassemble the nozzle and clean it completely? The answer is yes, the Atomizing Nozzles can be completely disassembled to allow for cleaning, maintenance or replacement of worn parts.
  2. Are the nozzles solvent resistant? The answer is also yes; the Atomizing Nozzles are made of AISI303 type stainless steel and can be cleaned with any normal solvent based cleaner.

Earlier in this article, I mentioned that we went through some application type questions. Here is a list of general questions that we normally ask a customer about their application in order to determine which in our selection would be best suited.

  1. What is the volume of liquid flow (G/Hr) needed for the application?
  2. What is the viscosity (cP) of the liquid being applied?
  3. What are the required spray pattern, size and shape required?
  4. Is the liquid under pressure (by pump or pressure pot)? If so, what is the liquid pressure?
    1. Side note: we have options for non-pressurized liquid by using our siphon fed nozzles.

If you have an application where you have a liquid that needs to be applied in atomized form to a target, or perhaps a humidification application, please give EXAIR Atomizing Nozzles your consideration.
