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

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.

Week 6 Back to Basics- Control the Pressure

If you’ve been following along with this blog miniseries, you know we’ve reached the final step in the Six Steps to Optimizing Your Compressed Air System. Each step so far has built toward this moment—and today we add the last piece of the puzzle.

The final step is simple but powerful: control the air pressure at the point of use to minimize consumption.

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

This is done by installing one of our pressure regulators, available in multiple pipe sizes and flow capacities. A small change in pressure makes a big impact. For example, reducing operating pressure from 100 PSIG to 80 PSIG lowers energy use by nearly 20%. In many cases, operations can run at even lower pressures, unlocking even greater savings.

This reduction in energy use is also coupled with the fact that pressure regulators make any compressed air-operated tool infinitely adjustable. Not all applications require the full output force or RPM, or conveying rate that can be achieved at full line pressure with a compressed air-operated product. And so the humble pressure regulator enables this ability for energy savings and control that is on par with any electrical control for voltage or even frequency. Pressure regulators also facilitate our working mantra to use the least amount of pressure and volume necessary to accommodate the application objectives.

All of our regulators are standard stock items, which means they can ship the same day if ordered by 2:00 P.M. Eastern Time. Plus, with 2D and 3D CAD models available through our CAD Library, you can design your entire compressed air system virtually before making a single cut in pipe.

This step, combined with the previous five, gives you a complete roadmap to compressed air optimization. From measuring usage and fixing leaks, to implementing engineered solutions, automating control, using intermediate storage, and now regulating pressure—EXAIR is here to help make the process straightforward and effective.

As always, if you’d like to discuss your application or explore how we can help you optimize your compressed air system, feel free to reach out.

Enhance Your EXAIR Product & More w/ Accessories

If you hang around with me for long enough, you will grow to understand that I love comedy movies. One of my favorite production groups is Broken Lizard. You might know some of their work and, just to be clear, I have seen all the movies, watched two of the guys’ TV shows, and listened to some of their podcasts. When trying to come up with a title for today’s blog, I looked up synonyms for “Accessorize”. The picture below shows the results.

If you haven’t seen Super Troopers, then I am not sure if we can continue to be friends. Actually, I won’t hold it against you. There is a scene in the movie where they are trying to get some information from a photo and so Ramathorn is sitting at a computer and working on the photo. He continually types and says, “Enhance” several times until the chief briskly informs him to just print the photo already. Unfortunately, I can’t share the clip here because there may be some inappropriate language at the end of the clip, so just believe my poor description that it is funny.

Well, all the products EXAIR offers in our Accessories catalog section will ENHANCE your point-of-use compressed air application. Whether it be a point-of-use filter/ oil removal filter, and a regulator with mounting brackets and coupling kits to ensure you have clean air being utilized. See the video below for just how well they work and why they are important to an installation.

Items like Swivel Fittings, Stay Set Hoses, and even lengths of Air Hose can give versatility in locations where hard piping and getting precise alignment of the air stream are needed. This can save the installer of a blowoff many fittings and hours of time on installation. The Swivel Fittings give a lock-in-place adjustment capable of 25° from centerline at 360° of rotation.

The Stay Set Hoses are another tool-free adjustable mounting option for point of use compressed air products. The ability to get rid of copper tubing, which is costly and can kink if proper tools aren’t used to bend it, is great for easy installation in the field. To see how easily they can be used, check out the video by John Ball below.

Even after these products we still offer a number of accessories that will aid operators in their production environment. If you want to discuss any part of the EXAIR product offering, please contact an Application Engineer today.

Common Compressed Air Drawing Symbols

The symbols on top denote the EXAIR products below (left to right): Flowmeter, Pressure Gauge, and Solenoid Valve

When it comes to drawings and diagrams to map out a process system, the piping and instrumentation diagrams (P&ID) are a great way to situate and find components.  They use different symbols to represent the types of products, the layout of the system, installation, and process flow.  These standard symbols are created by ANSI or ISO.  They are used in electrical, hydraulic, and pneumatic processes. I will cover some pneumatic symbols and the process flow in this blog.

A colleague, Russ Bowman, wrote an article about “Knowing Your Symbols Is Key To Understanding Your Drawings”.  As a reference, air compressors are the start of your pneumatic system, and there are different types as represented by the symbols below.

Air compressors are considered the fourth utility in industries because they use so much electricity, and they are inefficient.  So, you need to use the compressed air as efficiently as possible.  As a typical pneumatic system, the air compressors, receiver tanks and compressed air dryers would be on the supply side.  The distribution system, or piping, connects the supply side to the demand side.  This symbol is represented by a simple line.  The demand side will have many different types of pneumatic devices.  Since there are so many, ANSI or ISO has created some common types of equipment.  But if there isn’t a symbol created to represent that part, the idea is to draw a basic shape and mark it.

From top left, and then down: Automatic Drain Filter Separator, Oil Removal Filter, Pressure Regulator, and Super Air Knife

As an example, if I were to do a P&ID diagram of the EXAIR Super Air Knife Kit, it would look like the above diagram.  The kit will include the Super Air Knife with an Automatic Drain Filter Separator and a Pressure Regulator.  The Filter Separator is a diamond shape and, since it has an Automatic Drain, a triangle is placed at the bottom.  Filter Separators are used to clean the compressed air and keep the Super Air Knife clean.  The Automatic Drain will discard water and oil from the filter bowl when it accumulates over the float.  The next item is the pressure regulator, which is represented by a rectangle with an adjustment knob to “dial in” the desired blowing force.  And at the end, we drew a rectangle, which represents a Super Air Knife, as marked.

Using the P&ID diagram for the process flow is important.  You noticed that the Filter Separator would come before the Pressure Regulator.  This is significant when installing this system.  Did you remember the statement above about “using your compressed air as efficiently as possible”?  Inefficiencies come from two basic areas; pressure drop and overusing your compressed air.  Pressure drop is based on velocity.  The lower the velocity, the lower the pressure drop.  For the second part about overusing compressed air, the Pressure Regulator will help.  You want to use the lowest amount of air pressure as possible for the Super Air Knife to “do the job”.  The lower air pressure will use less compressed air in your operation.

EXAIR products are engineered to be safe, efficient, and effective in your compressed air system.  If you need help to place them in your P&ID diagrams, an Application Engineer can help you.  It is important to have the pneumatic devices in the proper place.  If you want to efficiently use your compressed air, you can use EXAIR products for your blow-off devices.  We have been doing this for a long time.
