EXAIR Siphon Fed Air Atomizing Liquid Spray Nozzles

Amongst EXAIR’s continuously growing product offering, some of the newest are a family of Air Atomizing Liquid Spray Nozzles that does not require a pressurized liquid source. These are known as the Siphon Fed Air Atomizing Nozzles. These nozzles can be easily implemented where a tank can be installed and lower the cost of the installation by not requiring a liquid pump, just point of use compressed air.

This action is done by the unique design of the air cap.  As the velocity of the air passes through the air cap, low pressure is created by a venturi.  The Siphon Fed Atomizing Nozzles can draw liquid from a suction height of 36” (91 cm), or gravity fed. They are manufactured from 303 stainless steel for durability and corrosion resistance. The Siphon Fed models can spray viscous fluids up to 200 centipoises and are used in many applications like rinsing, coating, cooling, quenching, humidification, or dust control. The images below showcases how simple the setup can be for the siphon and gravity fed installations.

EXAIR Siphon Fed Nozzles work with non-pressurized liquids, either siphoned (left) or gravity fed (right.)

EXAIR carries three different body sizes, 1/8” NPT, ¼” NPT, and ½” NPT ports; so, you can create a light mist or a heavy spray of liquid.  The maximum liquid flow rate is controlled by the air cap and liquid cap combination.  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.  The video below shows just how easily the changeover is done.

In addition to the three different inlet/body sizes, we also offer the Siphon Fed in both a round spray pattern or a flat fan spray pattern. These are also controlled by the air and liquid cap combination. This means it is easy to convert a round pattern that may be needed for a job, over to a flat fan pattern for the next setup. Each pattern is also available in several flow rates of liquid and air to dial in the performance required by the application.

Additionally, if you would like to positively shut the liquid flow off from the nozzle in order to prevent drips, over use of liquid, or to shut off the gravity fed liquid when not needed, the No-Drip versions of these nozzles is also available. This is easily controlled by simply reducing the compressed air operating pressure to below the designated cracking pressure of the patented No-Drip valve.

Thinking Outside of the Box

Over the years of working at EXAIR, I have spoken to thousands of customers. The applications we discuss can run the full range that is showcased in the Solutions section of our website. It is always fun to approach applications when we have to think outside of the box for a solution. Throughout the Application Engineering department, our level of experience here combined with the customer’s knowledge of their setup, sometimes results in a solution that is not straightforward. Sometimes, we have to think outside of the box.

What kind of application may we have encountered where the obvious solution wasn’t the one that worked? One of the best applications that came to mind for me is when a customer was attempting to lift/pick up a very porous piece of filter media like the pre-filter from a Heavy Duty HEPA Vac. This material is extremely lightweight and porous. When hearing from a customer, I want to pick this material up, my mind quickly goes to the E-Vac Vacuum generators which are used to generate vacuum to operate suction cups.

With this material however, the vacuum flow needed is quite extensive and there is another product which is going to be a more efficient use of compressed air. That product, the Super Air Amplifier. As you can see in the photo below, a 2″ Super Air Amplifier easily lifts the porous material and because the suction side is a nominal hose size a hose can easily be attached if needed. The image shows a single amplifier lifting a larger sheet from a bench, these could be organized in an array like suction cups to pick materials up.

The moral of the story is to keep an open mind for solutions, while one path will always work other paths may become a more efficient manner. These solutions don’t always fit inside a box nice and neat. The Super Air Amplifier fit this because the amount of air entrained is tremendous and can easily be utilized to pull low vacuum force/high flow applications. This is very similar to fume evacuation which would be a “normal” application for the Super Air Amplifier.

If you want to discuss any point of use compressed air application with us, contact an Application Engineer and let us help you determine the solution your job needs.

Hazardous Location AND Overheating Electronics? We Have You Covered!

Here in Ohio, we like to think we know a lot about the weather. Did you know there are more than 4 seasons? Heck, we have at least two Winters, and then a Pre-Summer, Spring, Summer, Heat is still coming – make it stop season, and Fall. Don’t forget the construction season where the lovely orange cones and barrels bloom on every major roadway, and then we also like to throw in brood weeks for the cicadas every now and then. Yeah, we get a full gambit of weather and the past week has brought out some heat. I know this isn’t just Ohio, we get calls from around the globe of atmospheric conditions that have caused issues within control panels. Some of these panels are in areas where the No Smoking sign is more than just a suggestion to better your health.
