How to choose the right product?

Here is a list of frequently asked questions (F.A.Q.) when it comes to our products (nozzles and humidifiers), how to choose the right one, what is important to consider when choosing, and what conditions to keep in mind when choosing.

Founded in 1954, IKEUCHI became the first company in the world to develop a ceramic tip industrial nozzle in 1961. Since then, we developed 42 000 different types of nozzles and humidifiers. We have been providing humidification solutions and spraying nozzles to the industry for half a century, and our expertise is still growing. Our engineers can help you and direct your search for the right product, and build your project for a better solution.

Our solution-providing approach and our dedication to our customer is the cornerstone of our business.

At IKEUCHI, our expertise can be seen in the quality of our products. Our nozzles are produced in our factories. These factories are based in Japanese cities (Nishiwaki and Kure) and Vietnam (Hanoi). We invest a lot of our energy and profits into research and innovation.
Indeed, we are very thorough with the production and quality requirements of our products. Our inspection process is extremely strict, and any default in a piece will immediately lead to the destruction of the whole lot.

This is the reason why, at IKEUCHI, we guarantee our spraying nozzles for Spray capacity and spray angle with an accuracy of plus or minus 5 % and 5 degrees at the time of installation. We are confident that any nozzle we deliver to you is working correctly. That being said, nozzles and humidifiers need to be handled with caution and in accordance with the recommendations of use.

To be able to differentiate between the various types of spray droplet sizes, a classification of droplet sizes can assist into clarifying which product is suitable or recommended for a particular application. Based on the classification provided by IKEUCHI, there are 5 types of droplet sizes:


  • Ultra-fine atomization: or Dry Fog (< 10 μm)
  • Fine atomization: or Fine Fog (between 11 and 100 μm)
  • Semi-fine atomization: or Fine Drizzle (between 101 and 300 μm)
  • Semi-coarse atomization: or Light Rain (between 301 and 1000 μm)
  • Coarse atomization: or Rain Storms (> 1001 μm)

Water droplet size matters a lot depending on the specificity of your project and your applications. Having no universal scale of measurement of water droplets, IKEUCHI decided to create its own with very specific methods to ensure the quality of our spraying nozzles. The actual size of a droplet depends on the measurement method and the spraying system, but we rank them with the immersion sampling method.


If you want to know more about droplet size, here is an article that gives every detail possible about droplet size measurement!

The size of a water droplets matters depending on your application. You can read more detail about this topic in this article: Bigger is not always better for water droplets

All our nozzles are produced in Japan, where we have our own factories. We have 3 factories in japan (Hyogo District and Hiroshima District) and 1 in Vietnam.

All our orders are sent to Japan and shipped to our client when the quality verification tests have been completed.

Nozzles are precision tools used in many industries to spray air, water, or a mix of liquid and air. They have multiple applications such as humidification, cooling, chemicals spraying, dust suppression, etc. Each nozzle has precise characteristics such as spray angle, spray capacity, spray pattern, and spray distribution. We offer 42.000 different references of nozzles.

Nozzles are used in applications such as :

  • Cooling
  • Drying
  • Spraying water or chemicals
  • Humidity control
  • Blowing
  • Pollution control
  • Coating
  • Etc.

Go back to the question list

  • One fluid nozzle = we call these nozzles hydraulic nozzles. You can spray water or other liquid for various applications.
  • Two-fluid nozzle = we call them pneumatic nozzles, often combining water and compressed air. They are capable of a much finer atomization compare to hydraulic nozzles.
  • Air nozzle = as the name indicates these nozzles supply air (blower type or with compressed air) for applications such as drying, cooling, blowing off, etc.

Which nozzle for which application?

It depends on the type of application, your industry, and your requirements. Some of our nozzles have common applications like our VVP series for cleaning machines, films, screens, etc.

But it is important to determine all the necessary conditions in which you will use the nozzle. Otherwise, our nozzle will provide insufficient performance and will not produce the necessary results. This could results in waste of energy, waste of costs, and generates control problems.

What are the necessary conditions to choose the right nozzle?

All explanations about nozzle diversity and how to pick a nozzle are in those articles  :

It will depend on your application, the temperature where the nozzle will operate, and the viscosity of the liquid you will spray. Depending on these requirements, we can help you determine the most suitable material depending on its:

  • Wear resistance;
  • Chemical resistance;
  • Heat resistance;
  • Pressure resistance.

After installation of our products, there is a lifetime for them to perform at 100% depending on the operating conditions. Therefore, each model don’t have the same lifetime. But you can easily check if the nozzle you are using is still operating at its highest performance or if it’s been used and deteriorating.

You can read more details about how to detect when to replace a nozzle in this article: Detecting nozzle performance problems and when to replace them?

Dry Fog is a feature of our Dry Fog Humidifier AKIMist® “E”. We define Dry Fog as a very fine fog with a uniform, mean droplet diameter (mean fog droplet size) of 10 μm or less.
Because Dry Fog’s exceedingly fine spray droplets remain intact without bursting when they come into contact with objects such as walls and people, they do not wet the machines, the operators, the environment.

That is why it is important for us to use our classification of water droplets in order to guarantee a none-wetting fog with our Dry Fog humidifier.

As there are many nozzles providers on the market with a different price range, it is important to point out that only nozzle manufacturer can guarantee the quality of the nozzles and its performance.

The danger by using a cheap copy product is mainly low quality and a high turn over of nozzles, increasing your cost on the long term.

As a manufacturer, we dedicate our service into supporting our customers to solve their issues and increase their productivity. That is why, we want to bring awareness to the existing copy products on the market that might endanger your production efficiency and quality.
