How Pressure Regulators Help You Save Compressed Air (and Money)

Compressed air is one of the most expensive utilities in any industrial facility; yet it’s also one of the most commonly wasted. Many systems run at higher pressures than necessary, driving up energy costs and increasing air consumption without improving performance.

That’s where EXAIR pressure regulators come in.

What is a Pressure Regulator?

A pressure regulator is a simple but powerful device that controls and stabilizes air pressure delivered to your application. Installed at the point of use, it allows you to “dial in” the exact pressure needed—no more, no less.

Inside the regulator, a spring and diaphragm system automatically adjusts airflow to maintain a consistent downstream pressure, even when supply conditions change.

Why Running at Full Pressure is Costing You

It’s common for compressed air systems to operate at full line pressure—often around 100 PSIG—even when the application doesn’t require it. The problem? Higher pressure directly increases air consumption and energy usage.

For example:

  • Reducing pressure from 100 PSIG to 80 PSIG can cut air consumption by nearly 20% and reduce power usage by about 10%.
  • Lowering pressure even further at the point of use can deliver 30%+ air savings in certain applications.

In short: if you don’t need the pressure, you’re paying for wasted air.

How EXAIR Pressure Regulators Save Air

1. Control at the Point of Use

Instead of running your entire system at one high pressure, EXAIR regulators let you fine-tune pressure exactly where it’s needed. This ensures each application operates at its optimal setting—not the system maximum.

2. Reduce Air Consumption Instantly

Pressure and airflow are directly related. When you lower pressure, you automatically reduce the volume of compressed air consumed.

A simple adjustment—turning down a regulator—can immediately lower SCFM usage without changing equipment.

3. Improve System Efficiency

Lower pressure reduces the workload on your compressor. In fact, decreasing system pressure can reduce compressor energy consumption by measurable margins, helping extend equipment life and reduce maintenance.

4. Eliminate Overuse and “Set-It-and-Forget-It” Waste

Without regulators, operators often compensate by increasing pressure “just to be safe.” Regulators remove that guesswork by locking in the correct pressure for consistent, repeatable performance.

Real-World Example

Let’s say an air knife application runs at 100 PSIG and consumes 42 SCFM. By reducing pressure to 60 PSIG:

  • Air consumption drops to 27.6 SCFM
  • That’s a 34% reduction in compressed air usage—with no loss in performance if the application still meets requirements.

Multiply that across multiple applications, and the savings add up quickly.

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

The Bottom Line

If your compressed air system is running at full pressure everywhere, you’re almost certainly wasting energy and money.

EXAIR pressure regulators provide a straightforward solution:

  • Lower pressure where possible
  • Reduce air consumption instantly
  • Improve overall system efficiency

Sometimes, the easiest way to save compressed air isn’t changing your equipment—it’s simply turning down the pressure.

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.

Save Money With Engineered Products, Then Save More Money With Rebates

One morning last summer, I turned on the water in the shower and waited for it to warm up. And waited…and waited. It was clear something was wrong, so I checked the water heater to find it emptying its contents into the floor drain, through the bottom of the tank, which I found later had rusted away. Between my better-than-average plumbing skills, having a son home from college, and finding out I could keep about $800 in my pocket if I bought a new one and replaced it myself, I woke the boy up (which turned out to be one of the more difficult tasks in the process), drove to my friendly neighborhood home improvement center, and bought myself a new water heater, and we had hot water by the time my wife got home from work that afternoon. Considering the way it started, it turned out to be a pretty good day. Not only was it more efficient (and therefore cheaper to run) than the one I replaced, the water heater I bought also qualified for a rebate, which increased my savings on the project to almost $900. That was some FANTASTIC icing on an already pretty decent cake.

Rewards like this for being energy conscious have been routinely offered by utility companies for years now. One time, I got a box of LED light bulbs, enough weather stripping for TWO houses the size of mine, and water-conserving shower heads, for free, from my electric company as part of a home energy audit. That was a pretty good day too.

Many utility companies across the country have similar programs for residential customers, and commercial ones too. Duke Energy (my free light bulb folks), for example, has a program they call Smart$aver that offers rebates and other incentives to companies for making energy-efficient improvements. Equipment that qualifies for these incentives includes process pumping systems, insulation for injection molding machinery & pellet dryer ducts, low friction v-belts for rotating machinery, and compressed air equipment.

That last one is what I wanted to write about today. It includes improvements to the supply side:

  • Receiver tanks
  • Cycling air dryers
  • Zero-loss condensate drains
  • Compressed air system audits

And the demand side:

EXAIR can help you out with the ones on the demand side. Consider:

Ultrasonic Leak Detector: this handheld device allows you to quickly & easily find leaks in your compressed air system.

EXAIR Model 9207 Ultrasonic Leak Detector filters out audible sound waves and focuses on the ultrasonic sound generated when compressed air finds its way out of a loose fitting, crack, etc. The parabolic disc (left) lets you find the area of the leak(s) and the tube extension (right) directs you to the precise location.
The copper tube used to have a crimped end that was aimed at the part in the chuck. They simply cut it off and used a compression fitting to install the Super Air Nozzle.

Super Air Nozzles: not only will these products get you a rebate, they’ll cost less to operate and will ensure OSHA compliance with regard to your use of compressed air. And they’ll do it quieter, to boot.

Replacing open-ended blow offs with Super Air Nozzles is oftentimes quick and easy. Compression fittings can be used to install them directly onto the ends of existing copper tubing. Stay Set Hoses can replace modular hose, which is great for machine tool coolant delivery but often misapplied for air blowing.

And frankly, I think the engineered products just look better too.

The Duke Energy Smart$aver program is for their customers in North Carolina, South Carolina, Indiana, Ohio, and Kentucky. If that’s not you, though, North Carolina State University’s NC Clean Energy Technology Center has a comprehensive Database of State Incentives for Renewables & Efficiency – DSIRE – that’ll help you find what’s available in your area.

Compressed air isn’t free. Heck, it isn’t even cheap. If you want to find out how much you can save by optimizing your compressed air system in Six Steps, give me a call. And if you want to sweeten the deal with rebates and incentives, contact your local utility company.

Flat Super Air Nozzles… Safe, Efficient, and Rebates?

1126 1" Flat Super Air Nozzle and 1122 2" Flat Super Air Nozzle
Left 1122 2″ Flat Super Air Nozzle and Right 1126 1″ Flat Super Air Nozzle

The EXAIR Flat Super Air Nozzles are manufactured to blow a wide, forceful stream of air.  Their engineered design creates a high-velocity, laminar air stream with minimal air consumption and low noise levels.  They come in two widths; 1” (25mm) and 2” (51mm).  EXAIR offers a standard Flat Super Air Nozzle and a High Force Flat Super Air Nozzle in two different materials: zinc-aluminum alloy and 316 stainless steel.  And with a metal construction, breakage is not a concern, and performance is not sacrificed even in the harshest of environments.  The unique patented shims inside the EXAIR Flat Super Air Nozzles will give you three improvements to the design and function.  First, they come in different thicknesses to create a wide range of forces.  In conjunction with a regulator, you can “dial” in the correct amount of force from a breeze to a blast without overusing your compressed air system.  The patented design also allows an even flow across the entire width of the air nozzle.  Lastly, the design helps to entrain the free ambient air, so that less compressed air is required, saving you money.  The EXAIR Flat Super Air Nozzles are effective in uniform blowing with safety and efficiency in mind.

Flat Super Air Nozzles have replaceable shims to vary performance.

To expand more on force adjustments with the Flat Super Air Nozzles, EXAIR has an easy way to change the shim to better suit your application.  You can increase or decrease the force of the nozzle by just removing two screws and changing the thickness of the shim inside.  EXAIR offers a Shim Set to give you a range of forces with the nozzles.  For the standard Flat Super Air Nozzle, they come with a 0.015” (0.38mm) shim for both the 1” and 2” sizes.  The corresponding Shim Sets will include a 0.005” (0.13mm), 0.010” (0.25mm), and 0.020” (0.51mm) shim.  The High Force Flat Super Air Nozzles will come standard with a 0.025” (0.64mm) shim, and the Shim Set will include a 0.020” (0.51mm) and a 0.030” (0.76mm) thick shim.  This is a unique feature, as the competition’s plastic flat nozzles do not have this option.

In addition to the features and benefits, the Flat Super Air Nozzles come with a lip for safety reasons.  Occupational Safety and Health Administration, OSHA, has a federal regulation, 29CFR 1910.242(b) to eliminate dead-end pressure.  This states that pressure over 30 PSIG (2 bar) can penetrate the skin and can cause injury or death.  With the safety lip on the Flat Super Air Nozzles, it eliminates that concern, even above 30 PSIG (2 bar) inlet air pressure.  Unlike pipes and copper tubes where the skin can cover and block the exit, the lip on the Flat Super Air Nozzles will allow the air to escape.  So, you cannot block the exit (reference photo above). 

EXAIR Safety Air Nozzles are engineered to be safe, quiet, and very efficient.  They are so efficient that many electrical companies offer rebates for efficient products to help reduce energy consumption.  EXAIR offers ways to calculate ROI (Return on Investment) and energy savings by using our products.  We even offer an Efficiency Lab to measure with calibrated equipment to do comparative analysis.  But if your local energy company has a rebate program, then you can receive even more money back.

EXAIR has partnered with Energy Star, a program of the U.S. Department of Energy (DOE) and the Environmental Protection Agency (EPA).  For statewide programs, The NC Clean Energy Technology Center has created a website that consolidates this information for you on their website: www.dsireusa.org.  “DSIRE is the most comprehensive source of information on incentives and policies that support renewable and energy efficiency in the United States”.  Since EXAIR’s products fall into this category, rebates can be applied to the use of our products. If there is a rebate available, you will find it on this site.

With the EXAIR Flat Super Air Nozzles, you can take advantage of their durability, safety, and efficiency for your blow-off devices.  And depending on the state that you are in, you may be awarded a rebate.  If you need any help with drawings, performance, or setup of our Flat Super Air Nozzles, you can speak with an Application Engineer at EXAIR.  We will be happy to help you.
