Liquid Atomizing Nozzle Used To Mark Furniture During Production

A major furniture manufacturer recently developed a need to replace an outdated spraying system with an efficient, engineered solution.  The need was to mark a production piece as it travels from one process to the next along a linear conveyor.  At intermittent points in the conveyor there is an opening through which liquid can be sprayed, but the opening is small and the available time is short.

The photo above shows the mounted nozzle awaiting final connection to air and liquid supply lines.  The pressure of these supply lines, combined with the fine tuning of the needle valve (top center of the Atomizing Nozzle) allow the liquid flow of the application to be dialed in to precisely the right point.  (Note that the photo has been rotated 180° and the nozzle actually sprays liquid upward.  EXAIR Atomizing Nozzles can be installed in any orientation.)

This application, with limited space and instantaneous or near-instantaneous liquid spray needs, is a great fit for an EXAIR Atomizing Nozzle.

Fast delivery, and precision control are two of the biggest advantages to using an engineered solution.  If you have an application in need of an atomized liquid spray, contact an EXAIR Application Engineer.

Finding the Right Atomizing Spray Nozzle

It seems that our Atomizing Spray Nozzles are becoming more and more popular to our customers and distributors overseas. Many times customers have applications that require a liquid be applied to a target surface in as efficient and sparing manner possible. At first glance, the EXAIR Atomizing Nozzle product line might look daunting to the un-initiated. However, if you break the application down into five simple questions, chances are you will be able to find the right nozzle that suits your need.

What are those five questions?

  1. What spray pattern do you want to produce? EXAIR offers Narrow angle round, wide angle round, flat fan, deflected flat fan, and 360° hollow circular spray flow patterns. Which one you pick depends on a variety of factors.
  2. What size area would you like to cover with the spray coming from the EXAIR Atomizing Nozzles? Sometimes it may be necessary to divide the area of a material coating process up over multiple nozzles.
  3. Is your liquid pressurized by either a pump or pressure-pot to get it to feed to the nozzle? If so what is the liquid pressure? EXAIR manufactures nozzles for pressurized applications as well as for applications where it is desirable or necessary to suck the fluid up into the nozzle with our siphon feed type atomizing nozzles.
  4. What is the viscosity of the fluid that you want to apply in the application? What we are concerned about here is the thickness of the fluid to be applied to make sure the nozzle will work well with that material. If the viscosity is under 300 Centipoise, an internal mix type nozzle works well. If it is over 300 Centipoise, then the more independently controlled, external mix type nozzles will be better to use.
  5. How much liquid do you want to apply to your target area in an hour’s time? Notice we want to know what the flow rate would be on an hour basis. For example gallons per hour or liters per hour. If the application rate is going to be given in gallons or liters per minute, these flow rates would be too high to be able to use an EXAIR Atomizing Nozzle appropriately.

With your answers to these five simple questions, an Application Engineer can help to recommend the right Atomizing Nozzle for your application. Give us a call or write to us about your spraying application today. We will be glad to help you sort through the data to come up with the right recommendation for you.

No Drip External Mix Atomizing Nozzle Wins Gold!

Published on by Dave WoernerLeave a comment

It is a very sad day for me at EXAIR… No, I’m not retiring or leaving the company, but today is my last day to write about Plant Engineering Product of the Year Awards …for this year. It has been quite an honor to write about four of our best innovations from the last year over the past weeks.  In case you missed the entries, you can click on the these links to read more about our other 2013 award winners: 316 Stainless Steel Dual Cabinet Coolers, 1 Inch Flat Super Air Nozzle or the Heavy Duty HEPA Vac. nodrip_EF Today’s post is about the No Drip External Mix Atomizing Nozzle, which the readers of the Plant Engineering magazine bestowed the gold award for fluid handling products.  EXAIR’s Liquid Atomizing Nozzles combine the liquid of your choice with compressed air to create a mist of atomized liquid.  The external mix nozzles have the highest liquid flow rate of any of EXAIR’s Liquid Atomizing Nozzles with flow rates up to 60 GPH.  They are a great solution for applications where independent air and liquid control is required.  Additionally, more viscous fluids can be used with the external mixing of the nozzle than either the internal mixing or siphon fed nozzles.  External Mixing Nozzles can be used to atomize liquids up to 800 centipoise. IMG_4031   In addition to the benefits of the external mix atomizing nozzle, this spray nozzle features a valve to positively stop liquid flow, when the compressed air drops below 30 psig. Any time you need to maintain a smooth finish or are spraying an expensive liquid, the no drip function can be invaluable to preventing rework, and ensuring a quality finish on each and every product.  The EXAIR no drip function is patent pending and does not require an additional air line to control the no drip mechanism, simplifying installation and functionality.
