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.

No Drip Atomizing Nozzle

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.

Internal Mix Atomizing Spray Nozzles Overview

EXAIR offers an ever-expanding selection of Atomizing Spray Nozzles.  One style with many iterations within the line is the Internal Mix.  Internal mix refers to the physical action of the compressed air atomizing the liquid before they leave the air cap. Because this action takes place inside the nozzle, internal mix atomizing spray nozzles are recommended for lower viscosity fluids. Water, water soluble/diluted lubricants, lightweight way oil, or rust inhibitors are a few examples that can easily be sprayed through these nozzles. The nozzles are also able to spray in five different spray patterns.

Internal Mix Atomizing Spray Nozzles are the perfect choice for fine mist and precise control.

The Internal Mix Atomizing Spray nozzles are available in Narrow Angle Round Pattern, Wide Angle Round Pattern, Flat Fan Pattern, Deflected Flat Fan Pattern and 360° Hollow Cone Pattern. These nozzles can cover anywhere from 1.5″ diameter up to 13′ diameter and almost any dimension in between. To cover this vast array of spray dimensions they are offered in three inlet port sizes, 1/8″, 1/4″ and 1/2″ NPT.

Internal Mix Atomizing Spray Nozzles

Each NPT size offers a variable spray pattern as well as liquid flow rates for each type of spray pattern. The 1/8″ nozzles are available up to 28 GPH of flow rate. The 1/4″ nozzles are able to flow up to 42 GPH. The 1/2″ models are able to flow up to 264 GPH. These flowrates can all be varied to minimal flows by adjusting the liquid needle valve. See the video below for a demonstration of that variability.

These nozzles are all easily installed and can be mounted with the available mounting brackets. One for each size.

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.

ad2010
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.

No Drip Internal Mix Atomizing Nozzles

Eliminate drips to conserve valuable liquids and improve product finishes!  EXAIR’s patented No Drip Atomizing Nozzle provides the same great performance as the the standard atomizing nozzles with the added benefit of positive liquid flow stoppage when the compressed air is shut off.

The No Drip option eliminates the occurrence of post spray liquid flow that results in unwanted drips that can mar a finish on painted or coated surfaces.  Also, excess liquid loss is minimized saving on expensive materials like chemicals or coatings.  When the compressed air is shut-off, the No Drip nozzle positively seals off the flow, eliminating the chance for a drip or lost liquid. Only one compressed air line is needed, as the line to combine and atomize the liquid also provides the no drip operation and control.

The No Drip Atomizing Nozzles are available in (3) types – Internal Mix, External Mix, and Siphon Fed.

The Internal Mix type operates under the principle that the air and liquid come together and mix ‘internal’ to the nozzle.  This type provides the finest atomization and smallest droplet size. The Internal Mix type of nozzle can be used with liquids up to 300 cP in viscosity.  Both the air and liquid sides are pressure fed.  The No drip Internal Mix Atomizing Nozzles are best for pressure fed applications not requiring independent air and liquid control.

The No Drip Atomizing Nozzles are available in (3) sizes – 1/8, 1/4, and 1/2 NPT – to provide a wide range of flow rates and pattern sizes.  The No Drip feature does not impact the flow rates compared to the standard models.  Minimum air pressure operation is 30 PSIG for the 1/4 and 1/2 NPT, and just 20 PSIG for the 1/8 NPT models.

Like the standard Internal Mix Atomizing  Nozzles, spray patterns include narrow and wide angle round, flat fan, deflected flat fan and a 360° hollow circular pattern offering a wide selection to best meet the application needs.

Operation at up to 180 spray cycles per minute is possible.  Air and Liquid Caps can be switched out to change the pattern and flow rates.
