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.

Protect Finishes and Save Liquid with EXAIR No Drip Atomizing Nozzles

A typical “liquid-only” nozzle is capable of producing droplet sizes of 300-4,000 microns. Atomizing Nozzles’ droplet sizes are consistently under 100 microns, and can be as small as 20 microns!

In today’s market, the cost of consumable products are on the rise; especially with paints, oils, and yes, even the cost of water.  You can help ease some of that cost by being more effective in spraying.  The EXAIR Atomizing Nozzles can achieve this objective.  By using compressed air, the liquid can be sheared into small micron-sized droplets.  As a reference, if the diameter of a particle is reduced by one-half, this will multiply the number of droplets by eight.  So, smaller diameter droplets will increase the coverage area and reduce liquid requirement in your application.

EXAIR manufactures three families of Atomizing Nozzles; Internal Mix, External Mix, and Siphon Fed.  We offer a variety of spray patterns and sizes; so, you can accurately target and use the proper amount of liquid in your system.  In this blog, I will narrow my discussion to the No Drip External Mix Atomizing Nozzles.

The No Drip option is offered with all of our Atomizing Nozzles.  This patented design is used to keep the expensive liquid from dripping out of the Atomizing Nozzles during off cycles.  When the compressed air is turned off to the nozzle, a valve inside the body will create a seal on the liquid side.  This No Drip function enhances the External Mix Atomizing Nozzle for intermittent processes as the liquid remains inside the body for quick spraying. With delicate applications, the unwanted drips will not occur to ruin the finish of your product.  Unlike some manufacturers, there is no need to run a separate compressed air line to operate the no drip function.  The External Mix Atomizing Nozzles with the No Drip options can give you the best performance in efficiency, effectiveness, and flexibility without any drips.

No Drip External Mix

To expand on the External Mix Atomizing Nozzle, it atomizes the liquid outside the nozzle.  The air and liquid supply are pressurized and can be controlled independently.  This type of Atomizing Nozzle will allow for higher viscous fluids to be sprayed up to 800 CPS, similar to SAE 40W oil.  Also, with the external mixing, it helps to diminish the drying effects of solutions which will reduce shutdowns for cleaning.  EXAIR manufactures these nozzles with stainless-steel construction making them compatible with many different kinds of liquids.  They are used in many applications like washing, coating, cooling, quenching, and dust control.

Spray nozzles in action.

EXAIR stocks three different body sizes in 1/8” NPT, ¼” NPT, and ½” NPT ports; so, you can create a light mist or a monsoon.  The combination of an air cap and a liquid cap controls the spray patterns and liquid flow rates.  These caps are easily interchangeable for each body size to change the spray patterns, control the amount of fluid, and reduce any downtime for cleaning.  The amount of liquid to be applied is easily adjusted by the inlet air pressure and liquid pressure.  So, you can dial in the exact amount of fluid required for your process to stop any waste or excess.

They have a compact design to mount inside tight areas, and we also have mounting brackets for easy attachment and positioning.   If your application needs versatility, fluid savings, and precise coverage; the No Drip External Mix Atomizing Nozzles could be the nozzle for you.  If you have any questions about our Atomizing Nozzles or spraying applications, an Application Engineer at EXAIR will be happy to help you.

These Plants Don’t Need Dirt, Just an Atomizing Spray Nozzle

Recently I was working with a company who grows plants using a method I’ve never heard of before, aeroponics. See I grew up on a farm, so I’m used to the old fashion way to grow crops! Dirt, water and sunlight, or as my grandpa would call them “The three pillars of life as we know it”.

So I had to do some research into aeroponics so I could understand if we could help him. It turns out aeroponics does not use a dirt medium, they relay on a very fine mist to provide the nutrients the plant needs to grow.  But its very important that the mist have droplet sizes of less than 50 microns, or the roots will not be able to absorb it.

At that point I knew EXAIR’s Atomizing Spray Nozzles were the right direction!

We ended up going with the AW8010SS Internal mix wide angle round pattern. And after playing with them the customer ran the nozzles at 5 PSIG air pressure and 10 PSI of  liquid pressure. running the nozzle every 10-15 mins kept the room at the perfect humidity for the plants they are growing.

They are planning to install up to 20 of the AW8010SS Internal mix wide angle round pattern in each section of their facility once they build their building!

To discuss your application and how an EXAIR Intelligent Compressed Air Product can help your process and save you money, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

EXAIR Siphon Fed Air Atomizing Nozzles: Overview

In today’s market, the cost of consumable products are on the rise; especially with paints, oils, and yes, even the cost of water.  You can help alleviate some of that cost by being more effective when spraying these liquids.

The EXAIR Atomizing Nozzles can accomplish this by using compressed air to shear the liquid into small micron-sized droplets.  By reducing the diameter of a particle by half, this will multiply the number of droplets by eight.  This will increase the surface area and coverage of the droplets; thus, requiring less material in your application.  EXAIR manufactures three families of Atomizing Nozzles; Internal Mix, External Mix, and the Siphon Fed.  In this blog, I will cover the Siphon Fed Atomizing Nozzles that EXAIR manufactures.

When no liquid pressure is available, the Siphon Fed Atomizing Nozzles will create a vacuum to draw the liquid into the nozzle.  This action is done by the unique design of the air cap.  As the velocity of the air passes through the air cap, a low pressure is created by a venturi.  The Siphon Fed Atomizing Nozzles can draw liquid from a suction height of 36” (91 cm), or it can be gravity fed from 18” (46 cm) away.  They are manufactured from stainless steel for durability and corrosion resistance.  The Siphon Fed models can spray viscous fluids up to 200 centipoise, and are used in many applications like washing, coating, cooling, quenching, and dust control.

EXAIR carries three different body sizes in 1/8” NPT, ¼” NPT, and ½” NPT ports; so, you can create a light mist or a monsoon.  The maximum liquid flow rate through each body size is controlled by the air cap and liquid cap.  A unique feature of the EXAIR Atomizing Nozzle is that the caps are easily interchangeable for each body size to modify the spray patterns, control the amount of fluid, and reduce any downtime if cleaning is required.  Here is a video that shows how this can be done:

The amount of liquid to be applied is easily adjusted by the siphon height, the inlet pressure, and the liquid adjusting stem.  So, you can dial in the exact amount of fluid required for your process to eliminate any excess waste. They are very compact and easy to install.  We carry mounting brackets for each size to allow for easy mounting and positioning.   Versatility is very important in saving, applying, and spraying costly fluids; and, the Siphon Fed Atomizing Nozzle has it.

Siphon Fed No Drip Option

To help reduce waste even more, EXAIR has a No Drip option.  This patented design is used to keep the expensive liquid from dripping out of the Atomizing Nozzles.  When the compressed air is turned off, a valve inside the body will create a seal on the liquid side.  For delicate applications, the No Drip options will eliminate unwanted drips that can ruin the finish of your product.  This option also enhances the function of the Siphon Fed Atomizing Nozzle for intermittent processes.  It will keep the liquid inside the body of the nozzle; so, when air pressure is applied, the Atomizing Nozzle will give an instant spray.

The minimum air pressure required to open the No Drip valve is 30 PSIG (2.1 bar) for the ¼” NPT and the ½” NPT port sizes, and 20 PSIG (1.4 bar) for the 1/8” port size.  Unlike some manufacturers, there is no need to run a separate compressed air line to operate the no drip function.  The Siphon Fed Atomizing Nozzle with the No Drip option is compact, efficient, and precise without any drips.

If you need to maximize the liquid dispersion and minimize liquid consumption, the EXAIR Atomizing Nozzles are the products to use.  Instead of researching the requirements for liquid pumps or pressure pots, the Siphon Fed Atomizing Nozzle can draw the liquid through the feed line and start spraying.  It can help reduce the cost of your project as well as save you money on your consumable products.  If you have an application involving liquid spraying, an Application Engineer at EXAIR can help determine the correct model for you.

Air Atomizing Spray Nozzles from EXAIR

EXAIR’s Atomizing Spray Nozzles are used in a variety of applications where atomization of a fluid is necessary. They combine a liquid source and compressed air to atomize the liquid into a very fine mist. With a wide variety of spray patterns and ability to customize the maximum flowrate, there’s an Atomizing Nozzle available for just about any application.

I’d like to take a moment to highlight two particular spray patterns that EXAIR has available: Internal Mix Deflected Flat Fan and Internal Mix 360° Hollow Circular. With both of these particular spray patterns an “internal mix”, the mixing of the compressed air and the liquid will occur inside of the nozzle.

The Model AD1010SS Internal Mix Deflected Flat Fan Pattern is a ¼ NPT Type 303 stainless steel nozzle designed for applications where mounting space is at a premium. The spray pattern deflects at a right angle to the nozzle’s orientation, allowing the spray to be placed precisely where it’s needed in close quarters. An ideal application for this particular spray pattern is coating the inside of an in enclosure or duct work.

AT5010SSpr_559x

The Internal Mix 360° Hollow Circular Pattern is available in two sizes: ¼ NPT and ½ NPT. These nozzles provide a large 360° circular pattern that works well in applications where a smooth, even coating is needed on the ID of pipe or duct work. Due to the large coverage area (up to 13’ in diameter for Model AT5010SS) they’re also ideal for applications including dust suppression, humidification, and cooling.

Both of these styles of spray patterns are available with or without the No-Drip feature. EXAIR’s patented No Drip Atomizing Nozzles work just the same way as the standard ones, but have the added benefit of positively stopping the liquid flow when compressed air supply is shut off. If your application cannot accept post spray liquid flow dripping onto the product or process, these nozzles are able to accommodate up to 180 cycles per minute with a required 30 PSIG minimum air pressure.

With all sizes and spray patterns available from stock with our Unconditional 30-Day Guarantee there’s no excuse to not give one a try!

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.
