Our customer in the automation/tool making industry has a need to spray a mold release type agent onto some specialized tooling they have developed and are testing. Originally, the customer had planned to use some sort of pressurized sprayer similar to those used in a garden. 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 to gain some acceptance of the recommendation.
- 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.
- 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.
- What is the volume of liquid flow needed for the application?
- What is the viscosity of the liquid being applied?
- What are the required spray pattern, size and shape required?
- Is the liquid under pressure (by pump or pressure pot)? If so, what is the liquid pressure?
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.
