The EXAIRHeavy Duty Safety Air Gun is a powerful air gun that is designed for use in rugged industrial environments. With extended use, there are parts that may wear over time. In this video blog, I will show you how to rebuild your EXAIR Heavy Duty Safety Air Gun using our Model 1902 Rebuild Kit.

Here at EXAIR we are confident that there is a lot to gain from using our products. Two of the biggest benefits of our Intelligent Compressed Air Products are a reduction in noise, and a reduction in Compressed Air usage. The latter will often lead to big money savings. Many times the savings our products offer will pay for the product itself! What is my Return on Investment going to be?
So, how do you calculate your ROI? The easy answer is that you don’t have to! You can use our Air Savings Calculator to calculate your savings for you. If you know your current air consumption (in SCFM), the new air consumption (SCFM) and the cost of the product, our calculator will turn that into monetary savings, as well as the calculated payback time in days.
Another option if you would rather not do the calculations yourself, is that you can send the item in question to our Efficiency LabTesting. The Efficiency Lab Testing is a free service that we offer to show you the possible savings by switching to one of our products. We will calculate the savings for you and send you the results of our findings. The final option – my favorite by the way – is that we can do the math right here:
For a simple example, I’m going to show the ROI of replacing a drilled copper pipe with an EXAIR Super Air Knife for a blowoff application. The calculations will be as follows:
Copper Pipe (1/4”): 3x 3/32” diameter drilled holes uses 9.4scfm per hole (28.2scfm total) at 80psig.
3” Super Air Knife: uses 8.7scfm at 80psig
Calculation:
For the yearly consumption, we need to find how many minutes in a year the blowoff will be operated:
For the Copper Pipe:
For 3” Super Air Knife
The difference between these two:
At this point, if you know your facilities cost to generate 1,000scf, you can use that to calculate how much you would save. For this example, we will use $0.25 to generate 1,000scf, which is used by the U.S. Department of Energy to estimate costs. This gives the following yearly savings:
With an investment of $273.00 (at the time of publishing), you can calculate the time it would take to pay off the unit:
From these numbers you can see that after 117 days, the 3” Super Air Knife will have paid for itself.
As you can see, it doesn’t have to take long for the knife to pay for itself, and then continue to contribute toward your bottom line.
EXAIR’s Line Vacs are a great option for replacing your ‘bucket and ladder‘ operation. There are many factors that need to be considered when selecting the best option – how far are you looking to convey? What conveyance rate are you looking to achieve? Is your material abrasive? – to name a few. Using data we have gathered from our controlled in-house testing, we can almost always recommend a stock-option Line Vac that will meet your application’s needs.
There are some instances however, when your needs will be better met with a custom solution. In this blog I wanted to highlight a few custom Line Vacs that we have produced for customers in the past:
This Special Mini Line Vac was designed with barbed fittings (unlike the hose or threaded fittings) for easier installation for a manufacturer of integrated circuit chips. It was used to remove microscopic debris. The small body and high vacuum flow made it a perfect fit for the confined working space.
This 1 ½” Flanged Line Vac was designed using PVDF to provide a superior chemical resistance. In this case, the unit was going to be exposed to a chloride wash which would corrode all versions of steel, including stainless steel. The QF Flanges were also added to provide easy disassembly when the Line Vac was scheduled for cleaning.
This Special Flanged Line Vac was used to convey a measured granulated material into a pouch. The funnel side was loaded with the pre-measured material and pushed into a mesh pouch when the air was activated.
This Special Flanged Refumigation Line Vac was used to retrofit existing machinery to remove acidic vapors resulting from surface etching of a silicon wafer. Where this would typically be a nice fit for a Stainless Steel Air Amplifier, the existing exhaust piping was lengthy with many bends that would have caused back pressure on any Air Amplifiers. In this case, they needed additional force from the Line Vac to overcome this downstream resistance.
This Special Threaded 1″ Aluminum Line Vac was used to remove fumes from a welding application, and needed to be threaded into a flame retardant filter bag. The custom threads allowed them to screw the filter bag directly onto the line vac with the added insurance of a threaded connection to prevent sparks from escaping the bag.
As you can see, we have many examples of non-stock Line Vacs (as well as special items from other product lines). If you have an application you would like to discuss, feel free to give me a call!
At EXAIR we are proud of our ability to ship our stock and catalog products the same day or the next day on orders received before 2:00pm ET. If you need a replacement part, or a new solution altogether, we can likely get the product to you in no time at all. There are certain applications, however, where the solution is more specific, and our stock options are not going to work out best. There may be a need for a different material, or a specific geometry to get the results the customer is looking for. For instances like this, we work with our customers to create a special, non-stock option.
I was recently working with a customer that needed an Air Knife to cool their material coming out of a hot process. This is a common application for our Air Knives, but for this particular customer, the shape of the Air Knife wasn’t going to fit in their machine. After some discussion, we determined that a curved Air Knife was going to be the best fit (pun intended).
After the customer provided some initial specifications, we put a drawing together. With some back and forth, reviewing drawings, and signing off on final designs, we set to work, producing their specially designed product. Within a few weeks, we were able to provide the specific solution to meet their needs.
If you have an application that needs a more tailor-made solution, give us a call!
