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.

Utility Rebates for Energy Savings

Since the establishment of EXAIR in 1983, customer satisfaction has always been the cornerstone of our business model.   This may seem like a common practice, but here at EXAIR, we like to go the extra mile.  We have over a 99.9% on-time delivery with thousands of products in stock.  We offer free expert technical help from our Application Engineers, as well as within EXAIR Blog writings and application search library.  We have an Efficiency Lab to report on comparison results with safety and compressed air saving.  We also offer a 30-day unconditional guarantee on our cataloged products for you to try.   So, what more can EXAIR do for you?

Compressors use large amounts of electricity to produce compressed air and are considered the fourth utility in most manufacturing plants.  EXAIR manufactures engineered products that can save compressed air and increase energy savings.  With that, EXAIR was able to partner with Energy Star.  “Energy Star is a government-backed symbol for energy efficiency helping to save money and to protect the environment through energy-efficient products and practices.” This commitment by EXAIR for reducing energy, increase safety for workers, and protecting the environment for future generations are effective ways to sustain a business value.

When large amounts of energy can be saved, electricity producing companies take notice.  Electrical suppliers started a rebate program for using engineered nozzles in their facility.  Similar to other energy-saving rebates, like LED light bulbs and high-efficiency furnaces, EXAIR engineered nozzles now fall into that same category.  If your electrical provider supports this program, the total cost to purchase and implement the EXAIR Super Air Nozzles are greatly reduced.  Even if a rebate program has not yet been implemented in your area, the idea of saving energy makes it very practical and environmentally sound.

The NC Clean Energy Technology Center created a website to consolidate all the electrical companies that offer rebates for efficient products and programs.  The website is 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.”  EXAIR engineered products fall into this category, so if a rebate can be applied to our products, it will be located on that site.

Back to the question above, what more can EXAIR do for you?  We all live busy lives at work and at home.  It may be difficult to find the proper programs from your local power companies.  Let EXAIR do most of the legwork for you.  Per your request, we can help find the proper forms for rebates when switching to EXAIR engineered nozzles.  With a rebate program, it makes it very cost effective to upgrade your pneumatic system to an energy efficient system.

Being backed by Energy Star, EPA, and rebate programs, together, we can save energy, improve the environment, and reduce compressed air usage.  If you would like to discuss how EXAIR can work for you, you can contact an EXAIR Application Engineer to get the most out of that extra mile.
