EXAIR Atomizing Spray Nozzles for Coating, Cleaning, Cooling

A recent customer in the automation / tool making industry had a need to spray a mold release agent onto some specialized tooling. Originally, the customer had planned to use some sort of pressurized sprayer. After some initial tests to prove the concept, the customer found that the moving mechanical parts of the sprayer became fouled by the release agent. And cleaning the internal parts was not easy to do.

In their search for a more permanent solution, the customer came across EXAIR Atomizing Nozzles. After going through some application type questions to narrow the focus down to one model, we determined that the customer would be best served by model AF1010SS (Internal Mix, Flat Fan Pattern Atomizing Nozzle). The customer had a couple of questions about the nozzle in order test the product.

  1. Is it possible to disassemble the nozzle and clean it completely? The answer is yes, the Atomizing Nozzles can be completely disassembled to allow for cleaning, maintenance or replacement of worn parts.
  2. Are the nozzles solvent resistant? The answer is also yes; the Atomizing Nozzles are made of AISI303 type stainless steel and can be cleaned with any normal solvent based cleaner.

Earlier in this article, I mentioned that we went through some application type questions. Here is a list of general questions that we normally ask a customer about their application in order to determine which in our selection would be best suited.

  1. What is the volume of liquid flow (G/Hr) needed for the application?
  2. What is the viscosity (cP) of the liquid being applied?
  3. What are the required spray pattern, size and shape required?
  4. Is the liquid under pressure (by pump or pressure pot)? If so, what is the liquid pressure?
    1. Side note: we have options for non-pressurized liquid by using our siphon fed nozzles.

If you have an application where you have a liquid that needs to be applied in atomized form to a target, or perhaps a humidification application, please give EXAIR Atomizing Nozzles your consideration.

Maintenance Free And Proud Of It

Caller: Do you sell rebuild kits?
Me: Yes, but…why?

This is a WAY oversimplified summary of the start of a popular conversation that an EXAIR Application Engineer might have with a caller looking to restore a particular product to proper operation. Truth is, most of our products have no moving parts, and if you supply them with clean, dry air, they’ll run maintenance free, darn near indefinitely. We’ve documented this in specific cases regarding a Reversible Drum Vac from 1999, a Vortex Tube from 1987, and a Cold Gun from 1985.

Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.

Caller: So…DO you sell rebuild kits?
Me: Yes, but…only when necessary.

It’s important to note that none of the products mentioned above needed any parts replaced to return to service. Sometimes, a good cleaning is all that’s required. We can help you with a video tutorial if you want to know how to restore a Reversible Drum Vac, an Air Knife, or an Atomizing Spray Nozzle, for instance.  And we’re making new videos all the time for product maintenance, operation, tips & tricks, etc.

Caller (again): So…you DO sell rebuild kits?
Me: Yes, of course!  I mean, who wouldn’t sell rebuild kits for their products?

Take our Safety Air Guns, for example. We offer Service Kits, if the trigger and/or internal valve of a Soft Grip or Heavy Duty Safety Air Gun starts to wear or leak, it’s super easy to replace. We’ve also got replacement springs for the “fail shut” feature of the ball valve of a Super Blast Safety Air Gun. Just about anything else that could be wrong with a Safety Air Gun’s performance can be addressed by cleaning the nozzle.

We also recently added Rebuild Kits for our Atomizing Spray Nozzles to inventory. These contain all of the seals (and moving parts, for the No-Drip models) to restore an EXAIR Spray Nozzle to rated performance.

Keep your EXAIR Atomizing Spray Nozzle (left) in perfect working order with a simple & inexpensive Rebuilt Kit (right of the nozzle.) Contact an Application Engineer to select the one for your product.

For other products, we can also provide replacement gaskets & seals for the Reversible Drum Vac & Chip Trapper products, O-rings for the Line Vacs, Chip Vacs, and Heavy Duty Dry Vacs, new elements for Filter Separators & Oil Removal Filters…just to name a few.

Bottom line: if your EXAIR product isn’t performing the way it used to, give me a call.  It will be my pleasure to help you get it working like new, so that you can continue to get the most out of it.

Step by Step Guide – Choosing Atomizing Spray Nozzles

EB1040SS

Atomizing spray nozzles atomize fluids to create a fine spray in a variety of patterns for a variety of uses. They are commonly used to mark products, paint or coat, cool, reduce dust, lubricate and clean parts.

With the numerous types of Atomizing Nozzles sold by EXAIR, it can be challenging to shift through all the information. We can help you to narrow down the field to quickly find the correct Atomizing Nozzle for your application.  In a summary, here are the basic questions that need to be answered:

1.) Are you using a pressurized liquid feed?

2.) What is the viscosity of the fluid?

3.) What is the liquid feed rate in gallons per hour (gph) or liters per hour (lph).

4.)  Should I use the No-Drip option?

EXAIR’s flow chart with easy-to-follow steps will walk you through the decision tree and land you at the best Atomizing Spray Nozzle for your application. In answering these simple questions, this chart will guide you to the correct page in our current catalog to get additional information and specifications.    Click on Link below to determine the best nozzle for you.

Video Blog: How To Clean & Replace Emitter Points for the Ion Air Gun & Ion Air Jet

This video will give a thorough walk-through on how to clean the emitter point on EXAIR Ion Air Jets model 8194 and Ion Air Guns model 8193.  This is the same procedure for replacing a damaged emitter point.  This procedure is for new style Static Eliminators with integrated grounded terminals, released on February 1, 2016.
