EXAIR’s Atomizing Nozzles for Decontamination Due to COVID-19

coronavirus-4957673_1920 (1)

At this time, countries across the world are all grappling with the constant change and disruption that is caused by COVID-19. As a worldwide supplier to manufacturers in a wide variety of industries, we’re seeing first-hand how important the manufacturing supply chain is. Many industries that we support including food, pharmaceutical, medical equipment, etc. are absolutely critical right now. EXAIR as a company is taking all necessary precautions to ensure that we can remain open to supply the manufacturers in these critical industries.

Manufacturers across the US and the rest of the world are re-purposing their facilities and production processes to manufacture medical supplies at a rapid pace. The situation evolves on a daily basis. The feeling is mutual among all of us, this entire situation is completely unprecedented and unlike anything we’ve experienced in our lifetime. I’ve recently spoken with numerous manufacturers and end users who are looking to utilize our products to help fight this pandemic.

One such product is EXAIR’s Atomizing Spray Nozzles. Designed to atomize fluids in a wide range of different spray patterns, they 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.

In the current situation, they’re being used for a range of applications for decontaminating rooms, personnel, and equipment. A 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.

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.

With the ability to produce a fine droplet size, the Atomizing Spray Nozzle is an ideal product to deliver the fine mist required for decontamination. If you have an application or process that could benefit from an EXAIR Intelligent Compressed Air Product please give us a call. We’re here, ready to help, as we all come together to fight this head on.

EXAIR Patented No Drip Atomizing Nozzles Improve Finishes, Save Liquids

EXAIR offers a wide variety of  Atomizing Spray Nozzles that can be used to coat, rinse or cool a surface. We manufacture (3) different types – Internal Mix, External Mix, and Siphon Fed – as well as 3 different sizes – 1/8″ NPT, 1/4″ NPT and 1/2″ NPT – all in 303ss construction, rated up to 400°F.

142 distinct models. 8 different patterns. Liquid flow rates from 0.1 to 303 gallons per hour. If you’ve got a spraying application, EXAIR has an Atomizing Nozzle for you!

Today I’m going to focus on the Internal Mix nozzles with the patented No Drip Functionality.

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. At the 41 second mark in the video below you can see the No Drip in Action!

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 centipoise 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.

Typical Applications

  • Painting

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.

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.

† Patent #9156045

 

Product Overview: No Drip External Mix Atomizing Spray Nozzles

EXAIR’s Atomizing Nozzles are commonly used to clean, cool or coat parts as well as humidification or to control dust. They are constructed of 303ss, providing superior corrosion resistance and are able to withstand temperature up to 400°F (204°C).

The Atomizing Nozzles are separated into 3 categories – Internal Mix, External Mix and Siphon Fed.

For today’s topic, we will focus on the No Drip External Mix Atomizing Nozzles.

No Drip External Mix Atomizing Nozzles provide the highest flow rates

The External Mix Atomizing Spray Nozzles require a pressurized liquid source and compressed air source to produce a mist of atomized liquid. With the liquid and air being mixed external to the nozzle, they are able to handle higher viscosity fluids above 300 cP.

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.

Available flow rates range from 2 GPH for our Model # EF9010SS 1/8″ No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH for the Model # EF6010SS 1/2″ No Drip External Mix Narrow Angle Flat Fan Pattern.

When making a selection, there are 5 common considerations to take into account:

  1. How much liquid flow do I need?
  2. Is the liquid pressurized?
  3. What is the viscosity of the liquid?
  4. How wide of an area needs to be treated?
  5. What type of spray pattern fits the application?

If you have an application requiring a fine mist of atomized liquid or if you’d like to discuss another product or application, contact one of our application engineers for assistance.
