5 Compressed Air Myths Engineers Still Believe (And the Truth Behind Them)

Published on by Jordan T ShouseLeave a comment

Compressed air is often called the “fourth utility” because it’s essential to modern manufacturing. Yet despite decades of innovation, many misconceptions about compressed air systems continue to circulate on plant floors.

These myths can lead to higher operating costs, unnecessary equipment failures, excessive compressed air consumption, and reduced productivity.

Let’s separate fact from fiction.

Myth #1: More Pressure Means Better Performance

This is one of the most expensive misconceptions in manufacturing.

When an application doesn’t perform as expected, many people simply increase the regulator pressure. While this may temporarily solve the problem, it often creates new issues:

  • Increased compressed air consumption
  • Higher energy costs
  • Excessive wear on components
  • More system leaks

Instead of increasing pressure, engineers should determine whether the application is using the correct air nozzle, air knife, or vacuum generator for the job. Properly engineered products maximize force while minimizing air consumption.

Myth #2: Open Pipes Are Just as Effective as Engineered Air Nozzles

An open copper tube or drilled pipe may seem like a simple, low-cost solution, but it’s one of the least efficient ways to use compressed air.

Engineered air nozzles are specifically designed to:

  • Entrain surrounding ambient air
  • Amplify airflow
  • Reduce compressed air consumption
  • Lower noise levels
  • Meet OSHA safety standards

Many facilities discover significant energy savings simply by replacing open pipes with “bolting on” engineered air nozzles.

Myth #3: Air Leaks Aren’t Worth Fixing

A small leak may not seem important. Especially one you can’t even hear.

Multiply that leak across hundreds of fittings, quick disconnects, hoses, and valves, however, and the losses become substantial.

Many facilities unknowingly lose 20–30% of their compressed air production through leaks alone.

Routine leak audits and preventive maintenance can dramatically reduce compressor runtime and utility costs.

Myth #4: Compressed Air Doesn’t Need Preventive Maintenance

Many facilities focus maintenance efforts on compressors while overlooking downstream equipment.

Dirty filters, damaged regulators, nozzles clogged with rust and other contamination, as well as worn fittings reduce performance and waste energy.

Preventive inspections should include:

  • Filters
  • Regulators
  • Hoses
  • Air knives
  • Nozzles
  • Vacuum generators
  • Cabinet cooling systems

Small maintenance tasks prevent much larger production issues.

Myth #5: Noise Is Just Part of Using Compressed Air

It doesn’t have to be.

High noise levels often indicate inefficient airflow and turbulence.

Engineered compressed air products reduce turbulence while entraining surrounding air, producing quieter operation without sacrificing performance.

Lower noise benefits both employee safety and OSHA compliance.

Compressed air systems continue to evolve, but many outdated assumptions remain.

Questioning these common myths can uncover hidden opportunities to reduce operating costs, improve reliability, and increase overall plant efficiency.

Whether you’re troubleshooting a blow-off application, cooling an electrical enclosure, conveying materials, or eliminating static electricity, choosing engineered compressed air solutions can make a measurable difference.

Instead of relying on trial and error, work with application specialists who can evaluate your process and recommend the most efficient solution for your specific application. Small changes in compressed air usage often lead to significant long-term savings.

Why Engineered Air Nozzles Outperform Open Pipes (And Cut Air Use by Up to 70%)

Published on by Jordan T ShouseLeave a comment

Compressed air is one of the most expensive utilities in any manufacturing facility—yet it’s often treated as “free.” One of the biggest contributors to wasted compressed air is the continued use of open pipes, drilled pipes, or homemade blowoffs for cleaning, drying, and cooling applications.

While these methods may seem simple and inexpensive, they are inefficient, unsafe, noisy, and costly over time. EXAIR Engineered Air Nozzles are designed to solve these exact problems. Often reducing compressed air consumption by up to 70% while improving performance.

Open pipes release compressed air directly to atmosphere with no control, no amplification, and no optimization. This creates several major issues:

Excessive Air Consumption

An open 1/4″ pipe at 80 PSIG can consume 25+ SCFM continuously. Multiply that across shifts, days, and multiple stations, and the cost quickly adds up.

Poor Performance

Open pipes create turbulent airflow that dissipates rapidly, requiring higher pressure and more air to achieve acceptable results.

High Noise Levels

Uncontrolled air release produces noise levels that can exceed OSHA limits, creating safety and compliance concerns.

Safety Risks

Open pipes can generate dangerous dead-end pressures and flying debris, posing serious injury risks to operators. Creating real situations where

What Makes EXAIR Engineered Air Nozzles Different?

EXAIR Engineered Air Nozzles are precision-designed to maximize force while minimizing air consumption. Instead of wasting compressed air, they use advanced airflow geometry to do more with less.

Air Amplification

EXAIR nozzles use the Coandă effect to entrain surrounding ambient air. For every unit of compressed air used, multiple units of free air are pulled into the flow—creating higher output force without increased air usage.

Optimized Flow Patterns

Rather than chaotic turbulence, engineered nozzles produce laminar, focused airflow that delivers better cleaning, drying, and cooling results at lower pressure.

Significant Air Savings

It’s common to see 30–70% reductions in air consumption when replacing open pipes with EXAIR air nozzles—often with improved performance.

Eleminate Safety Risks

Air nozzles and jets are designed to operate well above 30 PSIG while creating dead end pressures well below the OSHA limits. Giving you better performance safley.

Replacing open pipes with EXAIR Engineered Air Nozzles is one of the simplest and most cost-effective improvements you can make to a compressed air system.

If you’re serious about:

  • Reducing energy costs
  • Improving safety
  • Lowering noise levels
  • Getting more from your compressed air

…it’s time to stop blowing money into the air.

EXAIR Engineered Air Nozzles prove that better design beats brute force—every time.

Optimizing Compressed Air: 6th Step – Lower the Pressure!

Published on by Tyler DanielLeave a comment

The last step in EXAIR’s Six Steps to Optimizing Your Compressed Air System centers around air pressure. Unless you’re controlling your air pressure for each individual application, there’s a strong chance you can achieve quite a bit of savings by lowering the air pressure just upstream.

In any application necessitating the use of compressed air, pressure should be controlled to minimize the air consumption at the point of use. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air at the point of use can often be overlooked.

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

Pressure regulators utilize a control knob that is turned to either increase/decrease tension on a spring. The spring puts a load on the diaphragm which separates internal air pressure from the ambient pressure. Typically made of a flexible rubber material, these diaphragms react very quickly to changes in the air supply. By either increasing or decreasing the flow of air based on the load on the diaphragm, downstream pressure remains fairly constant.

While one advantage of a pressure regulator is certainly maintaining consistent pressure on your compressed air devices, using them to minimize your pressure can result in dramatic savings to your costs of compressed air. As pressure and flow are directly related, lowering the pressure supplied results in less compressed air usage. EXAIR recommends operating your Intelligent Compressed Air Products at the minimum pressure necessary to achieve a successful application. If you notice a desirable result at a pressure of 60 PSIG, or even less, there’s no need to run full line pressure. In-line point of use pressure regulators are the simplest and most reliable way to allow you to dial down the pressure for any compressed air operated product.

When selecting a pressure regulator for your application, it’s critical that it is appropriately sized to supply adequate volume to the point of use devices downstream. Doing so, minimizes the risk of experiencing “droop”. Droop is a decrease in outlet pressure from the specified setting due to an increase in flow rate.  Droop occurs when the demand at the point of use exceeds the volume of air that the regulator can supply. By ensuring the pressure regulator is rated to deliver a sufficient volume of air, you’ll reduce the chances of experiencing droop. EXAIR offers pressure regulators in kits along with many of our products. We’ve done the hard part for you and made sure they’re properly sized!

If you’re looking for ways to help lessen the demand on your compressor, EXAIR’s team of Application Engineers will be happy to help. Reach out to us via phone, chat, or e-mail and see for yourself just how easy it can be to start saving compressed air!

Let the EFC Turn Your Compressed Air Off!

Published on by Jordan T ShouseLeave a comment

Compressed air is not free! But when used correctly, it’s a tool that, in most cases, is the most effective option! The best way to save compressed air is to simply turn it off when it’s not being used. This might seem pretty simple, but there may be processes in your facility where this couldn’t be achieved by just turning a valve. In applications where product is traveling along a conveyor and must be dried, cooled, or blown off, there is likely some spacing in between the parts. It isn’t necessary to keep the blowoff running constantly if there are periods of intermittent spacing. To help reduce the overall load on the air compressor, implementing a solution to shut the air off in between each part can have a dramatic impact.

EXAIR’s Electronic Flow Control, or EFC, is designed to improve efficiency by reducing overall compressed air usage. It utilizes a photoelectric sensor that detects when the part is present. When it’s not, it triggers a solenoid valve to close and shut off the compressed air supply.

EXAIR EFC

One way to use the Electronic Flow Control would be to turn an Atomizing Spray nozzle on to coat your product.  For example see the photo below where you can use the EFC to sense the pants coming down the line. Then turn the air supply on to spray a bleach solution to get the weathered look you are after. Once the pants pass, the EFC will turn the nozzle off, replacing a manual operation while saving compressed air and your liquid solution!

Another use would be to tell when a hopper that is being filled by a Line Vac is empty or over filled.  You can adjust the sensor and the control module to sense that the hopper is empty, and it will turn the compressed air on to the Line Vac to then feed the hopper.  Then set the timer module so it will run for the length of time it takes to fill the hopper.  The other way would be to place the sensor at the top of the hopper and have it sense when the pile of media has reached the full level.

The EFC models available from stock can accommodate flows up to 350 SCFM. For applications requiring more compressed air, EFCs with dual solenoids are also available. If you have an application in one or more of your processes where intermittent compressed air use could help save you money, give us a call. We’d be happy to take a look at the application and help determine just how quickly the EFC could start paying YOU.
