Here’s to enjoying the company of good friends and family. Everyone at EXAIR wishes all of you a happy Thanksgiving, and would like to express our gratitude for being our customers and vendors – we appreciate you.
EXAIR will be closed Thursday and Friday, November 22 and 23 to be with our family and friends.
Did you know that you can find 35+ published Case Studies regarding many of the EXAIR products and how customers were able to save on compressed air and increase safety simply by installing and using one of our Intelligent Compressed Air Products? Case studies provide real world results and highlight any dollar savings, production increases, quality improvements, safety improvements, and/or problems solved. The Case Studies are a valuable tool which can help determine success within your plant or aid in convincing a manager to implement an air savings project. With registration, they can be found under the Knowledge Base tab on the main page of the website, or simply click here.
Once on the Case Study page, you can search and sort by Product type or Application. Reading through the Case Studies of the type of product(s) of interest can provide valuable information on the compressed air savings and safety improvements that others have achieved, and that you might be able to realize as well.
The Case Studies involve measurable data from actual processes and offer learnings that can relate to applications and processes that are similar to those in your facility.
Each Case Study begins with the Application Goal – what was it that was to be achieved by the installation and use of the EXAIR product.
Then, we review the Before EXAIR condition – what was the problem, and what was being used initially.
Next, we show the After EXAIR process – this details the EXAIR product(s) that were implemented, and how it was able to improve the process.
Finally, the Summary section – this shows the cost savings attained, from less compressed air usage, faster operation rates, lower quality defects, reduced sound levels, and so forth that have been achieved and documented.
We invite you to read, download, and share the Case Studies, and use them as another tool available to you to learn about EXAIR products and how they can improve your processes.
We are always interested in learning about the compressed air savings and increased safety that have been realized by the use of an EXAIR product, and if you could share that information with us and have it result in a Case Study, we would love to talk to you and discuss how we can work together.
Chances are if you have been on your job for a little while, you have noticed some processes or equipment that takes excessive time, wastes energy, etc.. and delivers less than optimal results. So, just how do you communicate those observations to management in your organization? You certainly do not want to embarrass yourself by having your idea torpedoed, nor let the company continue wasting money on inefficient processes or equipment. The question becomes, how do you present your cost savings plan to the management team? This blog will help you with that very question!
Your idea(s) for cost savings should be presented clearly and concisely with some key information highlighting the cost and the savings. The simplest way to accomplish this is to quantify the savings for a given period of time and the payback schedule. The payback schedule is generally calculated by dividing the cost of the project by the forecast savings. Generally speaking, the shorter the time required for payback, the better the odds of your project being approved.
To start the process generate a (1) page overview that states the problem, cost of your proposal and the forecast savings. A thorough and concise presentation will help sway any naysayers in the group, and you should include detailed information that includes current operating costs and how you arrived at those figures.
In the compressed air industry, EXAIR Intelligent Compressed Air products provide some easy installations and quick payback times without sacrificing production or quality – in many cases, we can improve production and quality. Let’s consider the case below, where open tubes were being used to blow off punch presses. We started by capping off (4) of the open tubes and trying one EXAIR 1100 Air Nozzle with a defined air pattern and we clearly needed more force. That is when we attached the second super air nozzle, and voila! We had the amount of force and the air pattern required for this application, all while greatly minimizing air consumption and noise! The image below shows what a sample air savings presentation sheet or test sheet may look like.
Considering the EXAIR1100 Super Air Nozzle are $39 each, you can calculate that the payback time is slightly less than 10 working days per press, since two nozzles were used for each press.
When considering larger and more in-depth projects, naturally more documentation and information will be required. In addition to the requirements for the above example, just be sure to include the following points:
List the action items for your proposal and any purchases that may be necessary.
Outline your proposed savings and document how you arrived at that number.
Discuss anything that may cause delays or not go as planned, and if possible, suggest viable workarounds.
Create a milestone schedule for all the major points in your plan.
If you would like to discuss increasing the efficiency of your compressed air usage, quieter compressed air products, and/or any EXAIR product, I would enjoy hearing from you. Give me a call.
Fluidics is an interesting discipline of physics. Air, in particular, can be made to behave quite peculiarly by flowing it across a solid surface. Consider the EXAIR Standard and Full Flow Air Knives:
If you’ve ever used a leaf blower, or rolled down the car window while traveling at highway speed, you’re familiar with the power of a high velocity air flow. Now consider that the Coanda effect can cause such a drastic redirection of this kind of air flow, and that’s a prime example of just how interesting the science of fluidics can be.
As fascinating as all that is, the entrainment of air that these products employ contributes to another principle of fluidics: the creation of a boundary layer. In addition to the Coanda effect causing the fluid to follow the path of the surface it’s flowing past, the flow is also affected in direct proportion to its velocity, and inversely by its viscosity, in the formation of a boundary layer.
This laminar, lower velocity boundary layer travels with the primary air stream as it discharges from the EXAIR products shown above. In addition to amplifying the total developed flow, it also serves to attenuate the sound level of the higher velocity primary air stream. This makes EXAIR Intelligent Compressed Air Products not only as efficient as possible in regard to their use of compressed air, but as quiet as possible as well.

A little while back, I worked with a large eyeglass manufacturer on a sunglass lens cooling application. In their setup, they were dry cutting film-coated lenses with a router and after the lenses are cut, they are passed through several different rinse cycles and inspected for scratches or other damage. They were seeing a high number of reject parts and determined that the heat being generated by the tooling, was causing the irregularities. In an effort to alleviate the condition, they used a section of open flexible tubing to blow compressed air at the bit, which helped a little, but they were still concerned with the amount of scrap material.
I recommended they use our Model # 3825 Adjustable Spot Cooler System in the process. The Adjustable Spot Cooler incorporates a Vortex Tube to provide a temperature drop from the incoming supply air temperature. Using the temperature control valve, the exhausting air temperature and flow can be adjusted to fit the application. The system includes a flexible hose to focus the cold air to the desired area until re-positioned. The system also features a magnetic base that allows for easy mounting. By incorporating the filter separator included in the system, they can remove any moisture and/or contaminants in the air supply, relieving any concern with contamination or damage to the part.
If you have a cooling application you’d like to discuss or for help selecting the best product to fit your need, give me a call at 800-903-9247.
Daniel Bernoulli was born in Groningen, Netherlands on February 8, 1700 and was part of a large family heritage of famous mathematicians – His father Johann Bernoulli, one of the first founders of calculus, his uncle Jacob Bernoulli and his older brother Nicolous. When he was only 7 years old, Daniel began to take an interest in mathematics but his father convinced him that there was no financial gain to be had in mathematics and recommended he focus his studies in business instead. Reluctant at first, Daniel would take his father’s advice under the one condition, that his father would tutor him in calculus and his theories of kinetic energy.
At 13 years old, Daniel attended Basel University where he studied logic and philosophy completing his bachelor’s degree by the age of 15 and earning his master’s degree just 1 year later. Over the years, Daniel’s relationship with his father was strained as a result of him plagiarizing his father’s findings. Eventually, his father passed without reconciling with Daniel. At 24, Daniel became a Professor of Mathematics at a University in Venice but resigned from the position just 9 years later in 1733.
His most recognized mathematical contribution, Bernoulli’s principle, came in 1938 while performing energy conservation experiments, and he published the results in his book entitled Hydrodynamica. He discovered that when fluid travels through a wide pipe into a smaller, more narrow pipe, the fluid begins to move faster. He determined that the volume or amount of fluid moving through the pipe remains unchanged but will conform to the shape of the pipe or container as it flows. He concluded that the higher the pressure, the slower the flow of the liquid and the lower the pressure, the faster the liquid flow.
The same principle can be applied to air. As air moves around an obstruction or object, it follows the profile of the part and begins to speed up.
Take for example our Super Air Nozzles. The compressed air exits the nozzle through a series of jets which induces a low pressure around the profile of the nozzle, drawing in ambient air. This entrainment of air, up to 25 times or more, results in a high outlet flow at minimal compressed air consumption.
Many of the products offered by EXAIR incorporate this science which can lead to a more efficient operation by lowering compressed air demand ultimately reducing operating costs.

Last year we announced that EXAIR will celebrate Founder’s Day each year on February 22nd (or the closest working day) in order to commemorate the birthday of our founder, Roy Sweeney. He founded the company in 1983 and drove EXAIR to become the strong, successful and innovative company that it has over the years. Today would have been his 84th birthday.
As we plan to every year, we choose to make this day a celebration and a day to mark our ongoing commitment to the service of others in keeping with the values that Roy and his wife Jackie felt (and feel) very strongly about. It is up to us to continue that commitment.
Like last year, we have made significant donations to organizations that are making a difference right here in our area:
We committed last year to expand our community involvement in 2018, and we have delivered upon that promise. I am proud to announce that EXAIR has established an Employee Volunteer Program that enables every full-time employee with at least 90 days of service to volunteer with organizations of their choice during the normal work week with full pay by EXAIR.
Through this further commitment, we expect that EXAIR and its employees will impact not just a handful, but dozens of organizations and make a much larger positive impact in the community starting this year.
So as we celebrate today with cake and funny memories, we wish Roy a happy birthday. We miss having him here. We remember what he did for all of us and for countless others. And we pledge to continue his commitment to helping those who need it.
