4 Mistakes Plants Might Be Making with Compressed Air (and How to Avoid Them)

Compressed air is one of the most versatile and expensive utilities in any plant. It powers tools, moves products, cools processes, and keeps production running smoothly. But it’s also one of the most commonly misused resources on the floor.

Small inefficiencies add up quickly, and many facilities are losing thousands of dollars a year without realizing it. The good news? Most of these issues are easy to fix once you know where to look, especially with engineered solutions from EXAIR.

Here are four of the most common mistakes plants make with compressed air, and how to avoid them.

1. Using Open Pipes Instead of Engineered Nozzles

The Mistake:
Blowing with open pipes or drilled tubes is still surprisingly common. It “kinda works,” but it’s incredibly inefficient, noisy, and unsafe.

Why It Matters:
Open pipes consume a massive amount of compressed air and can create dangerous dead-end pressure situations. They also produce high noise levels that can exceed OSHA limits.

How to Avoid It:
Switch to engineered air nozzles and knives like EXAIR’s Super Air Nozzles or the Super Air knife. These are designed to:

  • Reduce air consumption by up to 80%
  • Meet safety standards for dead-end pressure
  • Dramatically lower noise levels

The Result:
Immediate air savings, safer operation, and a quieter plant floor.

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

2. Running at Higher Pressure Than Necessary

The Mistake:
Many plants run their systems at higher pressure “just in case.” It feels safer—but it’s costing you.

Why It Matters:
Every 2 PSI increase in pressure can increase energy consumption by roughly 1%. Multiply that across your entire system, and the cost adds up fast.

How to Avoid It:
Use EXAIR’s pressure regulators to optimize pressure at the point of use instead of over-pressurizing the entire system.

The Result:
Lower energy bills and better control over your applications—without sacrificing performance.

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

3. Ignoring Compressed Air Leaks

The Mistake:
Leaks are often treated as “minor” issues and left unresolved.

Why It Matters:
Leaks can waste 20–30% of your compressed air output. That’s essentially money leaking out of your system 24/7.

How to Avoid It:

  • Conduct routine leak audits using the Model 9207 Ultrasonic Leak Detector
  • Fix worn fittings, hoses, and connections
  • Use efficient components that minimize unnecessary air use

Pairing leak reduction with efficient products from EXAIR ensures you’re not just fixing losses, you’re preventing new ones.

The Result:
Reduced compressor load, lower maintenance costs, and immediate energy savings.

4. Not Optimizing Airflow for the Application

The Mistake:
Using too much air—or the wrong type of airflow—for blowing, drying, or conveying applications.

Why It Matters:
Inefficient airflow leads to higher consumption, inconsistent performance, and unnecessary wear on equipment.

How to Avoid It:
Adopt engineered air amplification products like EXAIR’s Air Knives, Air Amplifiers, and Air Wipes. These devices entrain the surrounding air to:

  • Maximize output while minimizing compressed air use
  • Provide uniform, high-performance airflow
  • Improve drying, cleaning, and conveying efficiency

The Result:
Better process performance with significantly lower air usage.

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

Compressed air is too valuable to waste. The difference between an optimized system and an inefficient one often comes down to a few overlooked decisions.

By avoiding these common mistakes—and implementing engineered solutions from EXAIR—plants can:

  • Cut energy costs
  • Improve safety
  • Boost productivity
  • Extend equipment life

If your facility hasn’t evaluated its compressed air usage recently, now is the time. Even small changes can deliver fast, measurable results.

“Under Pressure” Pressure Regulators!

I recently recommended to a customer to turn their air pressure down on their system as low as their process would allow. Meaning regulate the pressure so you have enough to complete the operations needed but find that happy medium where your compressor isn’t working as hard to build those high pressures for no reason!

Compressed air is an amazing tool to have, and when used properly it can be more efficient that other non-compressed air tools that run off electricity. However, it’s pretty common to see compressed air systems running at their max just because.

Pressure Regulators “dial in” performance to get the job done without using more air than necessary.

Lowering the air system pressure reduces the compressor power consumption by about 1% for every two psi of lower pressure. Lowering the pressure also makes any unregulated operations reduce consumption by almost 1% for every one psi of pressure reduction. Not to mention the extra savings if your compressor system can turn down the compressor power because of the reduced flow and possibly shut off compressors that are no longer needed!

The best pressure at which to set your system is the level where your production can operate efficiently and effectively without waste: There is no right pressure—it depends on your operations and tools. You may have 90 to 100 psig at the compressor, but at the production machine, where the actual work is being done, you could have only 65 to 70 psig. In some cases, it may be even lower due to pressure drops in undersized piping, filters, regulators. The goal is to lower compressor discharge pressure without affecting the the operations at the end of the line.

Having artificially high plant-pressure can help you deal with surges in compressed air demand that might occasionally cause low-pressure and affect production. The higher pressure acts to store reserve air in the various volumes made up of receivers, pipes and such in your system. However, the higher pressure costs more to produce and makes unregulated end uses consume more air, which is an expensive trade-off. Another option is to make sure you have line pressure regulators at each point of use. This will allow you to regulate the operation to the pressure needed being sure to save compressed air and keep the over all system running more efficient.

You can regulate those point of use lines with a number of EXAIRs Pressure Regulators!

EXAIR offers a range of Pressure Regulators capable of handling air flow of up to 700 SCFM.

Adjustable Air Amplifiers: Versatile, Rugged, and EFFICIENT!

Adjustability is a key feature for several EXAIR Intelligent Compressed Air Products… for example our Adjustable Air Amplifiers.  The ‘adjustable’ part has to do with setting the air flow volume and force:

Just loosen the locking ring, and you can thread the plug out of, or in to, the body to increase, or decrease the flow and force of the developed flow.  There’s a hole in the plug (opposite the “EXAIR.com” stamp) so you can use a spanner wrench (another adjustable tool!) to thread the plug in or out.

You can get an amazing range of flow from a little twist*:

These are the performance values for a Model 6042 2″ Aluminum Adjustable Air Amplifier with a compressed air supply pressure of 80psig. Regulating the pressure can give you even lower…or higher…flows.                                              *0.002″ to 0.010″ is about 1/4 turn of the plug.

A gap of about 0.010″ is about the max for 80psig supply pressure.  Above that, the air flow overwhelms the Coanda profile, creating a turbulent ‘storm’ in the throat, hampering the efficiency and effectiveness. The proper “adjustment” for that is to select the next larger Air Amplifier!

While the range of air flow is certainly impressive, their versatility is another major factor in their selection.  I reviewed our Application Database (registration required) for real-life details on Adjustable Air Amplifiers “in the field” and found a litany of other benefits that made them better suited to particular installations than a Super Air Amplifier:

  • A customer who builds automated equipment incorporates the Model 6031 1-1/4″ SS Adjustable Air Amplifier to blow open bags with a puff of air as they move into position on an automated filling machine. They use it because it’s available in stainless steel construction, and it’s still compact & lightweight.
  • A mattress manufacturer uses Model 6043 3″ Aluminum Adjustable Air Amplifiers to cool mattress springs.  They’re lightweight, the perfect size to match the springs’ profile, and they can “dial them out” for high heat removal before putting springs on a rubber conveyor.
  • A tier 1 automotive supplier has Model 6234 4″ SS Adjustable Air Amplifier Kits installed on their robotic paint line to blow off moisture from parts to prevent water spotting between the wash cycle and the oven.  They use them because the stainless steel construction holds up to high heat due to the proximity to the ovens.
  • A food plant uses Model 6031 1-1/4″ SS Adjustable Air Amplifiers to improve the drying time of 3,000 liter mixers that must be washed between batches of different products.  The stainless steel construction holds up to the rigors of the frequent washdown in this area.
  • A bedding manufacturer replaced a regenerative blower with a Model 6041 1-1/4″ Aluminum Adjustable Air Amplifier for trim removal on stitched fabric at bedding manufacturer.  The blower was prone to failure from lint & dust; the Air Amplifier, with no moving parts, is not.  It’s also compact, lightweight, and virtually maintenance free.
  • A light bulb manufacturer installed Model 6030 3/4″ SS Adjustable Air Amplifiers on the ends of open pipes that were used to cool mercury lamp wicks.  This reduced noise levels significantly while providing the same cooling rate, and the stainless steel construction holds up to the heat of the operation.

Because of the simplicity of their design, Adjustable Air Amplifiers are also extremely adaptable to custom applications.  We’ve added threads or flanges to the inlets and outlets of several different sizes, to accommodate ease of mounting & installation:

Among other custom Air Amplifiers, we’ve put (left to right) threads on the outlet, ANSI flanges on the inlet/outlet, Sanitary flanges on the inlet/outlet, and Sanitary on the inlet/ANSI on the outlet. How are you installing your Air Amplifier?

Adjustable Air Amplifiers are available in both aluminum and 303SS construction, to meet most any environmental requirements…except extreme high heat.  In those cases, the Model 121021 High Temperature Air Amplifier is rated to 700°F (374°C) – significantly higher than the Aluminum – 275°F (135°C) or the Stainless Steel – 400°F (204°C).  They’re commonly used to circulate hot air inside furnaces, ovens, refractories, etc.

A Model 121021 1-1/4″ High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

Adjustability.  Versatility.  Durability.  If you’d like to know more about the Adjustable Air Amplifier, or any of EXAIR’s Intelligent Compressed Air Products, give me a call.
