No Drip Atomizing Spray Nozzles: Overview

Are you tired of your dripping nozzle leaving puddles on your equipment and making a mess? Do the liquids you use to treat or coat your materials cost you a great deal of money? EXAIR’s No Drip Atomizing Spray Nozzles have been engineered eliminate drips; these patented nozzles contain a spring mechanism that when the air pressure reaches above 30 psig the valve will open allowing the liquid to escape out.

EXAIR No Drip Air Atomizing Spray Nozzles come in three styles. Internal mix, External mix and Siphon fed. 

One of the most commonly used types of No Drip Atomizing Spray Nozzles is the Internal Mix. The Internal Mix nozzle mixes the liquid and the air inside the cap and produces the finest droplet size out of the three. Due to the fact that the liquid and air are mixed in the cap, Internal Mix nozzles are used on liquids that have a lower viscosity (less than 300 cP). This means that they are usually used on liquids such as water, water soluble/diluted lubricants, lightweight oils, or rust inhibitors.

External Mix No Drip Atomizing nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These are best when precise liquid flow is needed. External mix nozzles can be used when the liquid viscosity is above 300 cP. 

Siphon Fed No Drip Atomizing nozzles require no liquid pressure and can be use dwith gravity fed liquids or siphon liquid from a height as much as 36 in. (91cm). These can be used with liquids up to 200 cP. 

No Drip Atomizing Nozzle
The No Drip Atomizing Spray Nozzles share the same spray patterns as our line of standard atomizing spray nozzles. This means that they are available in Narrow Angle Round Pattern, Wide Angle Round Pattern, Flat Fan Pattern, Deflected Flat Fan Pattern and 360° Hollow Cone Pattern. Along with the five different spray patterns they also come in three different inlet sizes of 1/8″, 1/4″ and 1/2″ NPT.
No Drip Flat Fan Spray Nozzle
Each NPT size also comes in a variety of different sizes in the corresponding spray volume. For example, the 1/8” No Drip Internal Mix Flat Fan Nozzles have for different Nozzles with a flow rate ranging from 3.47 GPH to 28 GPH (13.2 LPH to 105.99 LPH). This gives the No Drip Internal Mix Atomizing Nozzle 36 different variations to fit your application.

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.

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.

EXAIR Internal Mix Atomizing Nozzles: Overview

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

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 with less liquid.  The EXAIR Atomizing Nozzles  can accomplish these objectives.  By using compressed air to shear the liquid, small micron-sized droplets are produced.  As a reference, reducing the area of a particle by one-half will multiply the number of droplets by eight.  With smaller diameter particles, it will increase the surface area and the coverage; thus, requiring less liquid in your application.

In addition, with a variety of spray patterns, you can accurately target the liquid without having excess spillage around the product.  EXAIR manufactures three families of Atomizing Nozzles; Internal Mix, External Mix, and Siphon Fed.  In this blog, I will be discussing the Internal Mix Atomizing Nozzles.

The Internal Mix Atomizing Nozzles are designed, like the name suggests, to atomize the liquid inside the nozzle.  This means that the liquid and air streams will come together just before leaving the Atomizing Nozzle.  For this type of Atomizing Nozzle, the air and liquid supply are pressurized and independently controlled.

The Internal Mix Atomizing Nozzle can spray fluids with a viscosity below 300 CPS (similar to SAE40 oil).  EXAIR manufactures these nozzles with stainless-steel construction; making them compatible with many different kinds of liquids.  And they are used in many applications like washing, coating, cooling, quenching, and dust control.

Atomizing Nozzle

EXAIR carries three different body sizes in 1/8” NPT, ¼” NPT, and ½” NPT inlet ports; so, you can create a light mist or a monsoon.  Each body size has different air caps and liquid caps to control the largest liquid flow rates.  This will allow you to have finer adjustments of your liquid spraying.  These caps are easily interchangeable to change the spray patterns, spray amounts, and to reduce downtime if cleaning is needed.

Other features for the Atomizing Nozzles are the mechanisms to precisely regulate the amount of liquid being sprayed.  The liquid adjusting stem can  control the liquid flow into the Atomizing Nozzle.  Along with inlet air pressure and liquid pressure, you can “dial in” the exact amount of fluid to end any waste or excess. They have a compact design to mount inside tight areas, and we carry mounting brackets for easy attachment and positioning.   Versatility is very important in saving, applying, and spraying costly fluids, and the Internal Mix Atomizing Nozzles have it.

No Drip Atomizing Family

To help reduce excess fluid even more, EXAIR has a No Drip option.  This patented option is used to keep the expensive liquid from dripping out of the Atomizing Nozzles during off cycles.  A valve inside the body will create a seal on the liquid side when you turn off the compressed air.  For delicate and sensitive applications, the unwanted drips will not occur with the No Drip option to ruin the finish of your product. This option also enhances the Internal Mix Atomizing Nozzle for intermittent spraying processes.  It will keep the liquid inside the body of the nozzle; so, when you apply air pressure, the Atomizing Nozzle will give an instant spray.

Unlike some manufacturers, there is no need to run a separate compressed air line or have a liquid solenoid valve to stop the dripping.  The Internal Mix Atomizing Nozzles with the No Drip options can give you the best performance in efficiency, effectiveness, and flexibility without any drips.

If you need to maximize the liquid dispersion and reduce consumption, the EXAIR Atomizing Nozzles are the products to use.  The Internal Mix Atomizing Nozzles can shear the drops into micron-sized particles, saving expensive consumable oils and liquids.  If you have a spraying application, an Application Engineer at EXAIR can help you to decide the correct model.

EXAIR External Mix Atomizing Nozzles – For Use with Viscous Fluids and High Flow Rates

EXAIR’s Atomizing Spray Nozzles are used to atomize fluids in a wide range of different spray patterns. They utilize a small amount of compressed air which mixes with the liquid supply to create a fine mist of atomized liquid. EXAIR manufactures Atomizing Spray Nozzles in (3) different varieties: Internal Mix, External Mix, and Siphon Fed. For this blog, I’m going to focus on just the External Mix variety.

extmixeffam

On all External Mix Atomizing Nozzles the volume of liquid is easily adjusted by adjusting the valve stem on the standard Atomizing Nozzle, or by regulating the liquid pressure (the only option with the No-Drip style). Increasing the liquid pressure will result in an increased liquid flow rate.

The External Mix nozzles have the highest flow rates and can be used with liquids with a viscosity greater than 300 centipoise (cP). Since the air and liquid are mixing just outside of the nozzle, thicker liquids have a lesser chance of clogging in the nozzle. Both the liquid stream and the air stream will come into contact with each other just outside both the air and liquid caps. The compressed air breaks the liquid up into very small particles, allowing you to use much less liquid than a liquid only nozzle.

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. The External Mix Atomizing Nozzle is available in the standard configuration as well as the No-Drip style.

The No-Drip Atomizing Nozzle is used in a variety of applications where any liquid dripping from the nozzle after the air supply has shut off would cause a problem. This is common in painting applications where any paint dripping would affect the quality.

The External Mix Atomizing Nozzle is available in (3) different sizes: 1/8” NPT, ¼” NPT, and ½” NPT. If your application could benefit from utilizing the fine atomized spray of liquid look no further than EXAIR’s Atomizing Nozzles. With all sizes and configurations available from stock, we can get one out to you quickly!
