Environmental Impacts: Be Efficient. 

Published on by John BallLeave a comment

Since the establishment of EXAIR in 1983, customer satisfaction has always been the cornerstone of our business model.   This may seem like 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 of energy efficiency, helping to save money and to protect the environment through energy-efficient products and practices.” This commitment by EXAIR to reducing energy, increasing 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 facilities.  Similar to other energy-saving rebates, like LED light bulbs and high-efficiency furnaces, the 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 is 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.

Another energy-saving tip from Energy Star refers to waste from leaks.  They recommend a leak prevention program to help improve energy savings.  As part of that program, EXAIR does offer an Ultrasonic Leak Detector.  To tell a common success story about the Ultrasonic Leak Detector, an EXAIR customer had a 50-horsepower air compressor.  It started to overwork, overheat, and occasionally shut down.  They thought that they would need to buy a larger air compressor to keep the plant running.  In discussing that a company without a leak prevention program could have as much as 30% waste, they decided to purchase an Ultrasonic Leak Detector.  They checked every fitting and connection in the facility.  When they finished checking the compressed air system, they found a total of 91 leaks.  Not only did this save on energy waste, but it also saved money by fixing the leaks and not expanding the capital expenses in the company.

With EXAIR 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.

Maintaining Your Compressed Air System

Published on by Jordan T ShouseLeave a comment

A poorly maintained compressed air system wastes energy, increases operational costs, and risks unexpected failures. Common issues include leaks, pressure loss, contamination (like moisture or oil). Studies suggest that up to 30% of compressed air is lost to leaks in an average system, while contaminants can damage downstream equipment or spoil products. Routine maintenance tackles these problems head-on, ensuring reliability and cost-effectiveness.

Key Maintenance Practices

  1. Monitor and Replace Intake Filters
    The air compressor draws in ambient air, which is often laden with dust, dirt, and water vapor. The intake filter is your first line of defense, protecting the compressor’s internals from wear. Over time, debris buildup increases pressure drop, forcing the compressor to work harder and reducing efficiency. Check the filter regularly—typically monthly—and replace it when the pressure differential exceeds the manufacturer’s recommended limit (often around 5-10 psid) or at least annually.
  2. Manage Moisture with Dryers and Drains
    Water vapor in compressed air condenses as it cools, leading to rust in pipes, damage to pneumatic tools, and quality issues in applications like painting or food processing. A dryer—whether refrigerated, desiccant, or membrane—is crucial. For smaller systems or point-of-use applications, inspect and clean dryer coils or replace desiccants as per the manual (usually every 1–2 years). Automatic drain traps should also be checked quarterly to ensure they’re removing condensate effectively.
  3. Audit for Leaks
    Leaks are silent efficiency killers. Even a small 1/8-inch hole at 100 psig can cost over $1,000 annually in wasted energy. Conduct a leak audit every 6–12 months using an ultrasonic leak detector. Focus on fittings, valves, and older piping sections, where vibration or corrosion often takes a toll. Repairing leaks promptly can save 20-30% on energy costs. EXAIR’s 9207 can help with this task.
  4. Optimize Pressure Settings
    Over-pressurizing the system to compensate for downstream losses wastes energy—every 2 psig increase adds about 1% to power consumption. Use pressure regulators at the point of use to deliver only what’s needed. Monitor system pressure monthly to ensure it aligns with demand, adjusting as equipment or processes change.

How EXAIR Products Enhance Maintenance and Efficiency

EXAIR’s Intelligent Compressed Air Products are engineered to complement these maintenance practices. Here’s how some specific items can help:

  • Ultrasonic Leak Detector (Model 9207)
    Pinpointing leaks in a noisy compressor room can feel like finding a needle in a haystack. EXAIR’s Ultrasonic Leak Detector uses sound wave detection to identify leaks with precision, even in high-decibel environments. Regular use during audits—say, every 6 months—helps maintenance teams catch and fix leaks early, slashing energy waste. Its portability and ease of use make it a must-have for proactive upkeep.
  • Automatic Drain Filter Separators
    Moisture and particulates in the air stream can clog tools or ruin products. EXAIR’s Automatic Drain Filter Separators (available in various port sizes, e.g., 1/4″ to 1-1/2″ NPT) feature a 5-micron filter and centrifugal separation to remove bulk liquids and debris. The auto-drain feature expels collected water without manual intervention, reducing maintenance time. Replace the filter element annually or when the pressure drop hits 10 psid to keep air quality high and downstream equipment safe.
  • Oil Removal Filter
    For applications requiring ultra-clean air—like electronics assembly or pharmaceutical production—the Oil Removal Filter takes filtration further. With a 0.03-micron coalescing element, it traps oil vapor and fine particles, coalescing liquids for gravity drainage. Pair it with a Filter Separator for a two-stage approach, and replace elements yearly to maintain performance. This ensures sensitive equipment stays contaminant-free with minimal upkeep.
  • Pressure Regulators
    Excessive pressure at the point of use is a common efficiency drain. EXAIR’s Pressure Regulators (included in many product kits) let you dial in the exact pressure needed—e.g., dropping from 100 psig to 80 psig can cut air usage by nearly 20%. Install them downstream of filters for accurate control, and check settings quarterly to match evolving process demands. They’re a simple, maintenance-free way to optimize demand-side efficiency.

A well-maintained compressed air system isn’t just about avoiding breakdowns—it’s about maximizing efficiency and minimizing costs. By pairing routine checks with EXAIR’s engineered solutions, you can tackle leaks, contamination, and over-pressurization head-on. The result? A system that runs smoother, lasts longer, and keeps your energy bill in check. Whether you’re blowing off parts, powering tools, or cooling processes, these strategies and tools ensure your compressed air works as hard as you do.

What’s So Great About The New EXAIR Catalog #35?

Published on by Russ BowmanLeave a comment

This may seem biased, but my answer is, “EVERYTHING!” Now, that may SEEM biased, but consider the fact that, as an Application Engineer, I have a front row seat for the “Innovation Show” that is EXAIR. The attention to detail that gets paid to the design, testing, verification, and manufacturing of new products constantly reminds me that it’s a level of excellence that EXAIR’s founder, Roy Sweeney, instilled and promoted in our culture from when he started this business in 1983, until his passing in 2016. It’s a testament to his legacy that, not only does it continue; it shows no signs of slowing down. It’s that level of excellence that’s always made it easy for me to speak with confidence about the quality, performance, durability, and effectiveness of all of EXAIR’s engineered compressed air products.

Our Marketing folks proudly passed out copies of the new EXAIR Catalog #35 the other day, and I immediately started immersing myself in that pride as I thumbed through. I thought of 12 years (for me) worth of success stories in helping customers get the most out of their compressed air systems through the use of our products, and our expertise in not only those products’ implementation, but how they can best fit into those customers’ air systems, overall. I wasn’t too far in to my thumbing through, when the “new stuff” really started making an impression on me:

Ultrasonic Leak Detector: Model 9207 is the first new product you’ll see if you start at the beginning. It has the same functionality and tools (parabolic disc for finding out you have leaks in a particular area, and a tubular extension so you can track the leak to its exact location), and some nice upgrades: it’s powered by four AA batteries (instead of a 9V) and comes with a set of earbuds (which I personally prefer over the previous model’s earphones, which I always considered a compromise between headphone & earbuds, with the benefits of neither). It’s never been easier to find those costly leaks in your air system, and fix them.

1/2 NPT HollowStream Liquid Atomizing Spray Nozzles: We’ve had these in 1/4 and 3/8 NPT sizes for a while now, with the ability to spray up to 7.28 gallons per minute. The 1/2 NPT models almost double that capacity to a flow rate of 14 gallons per minute. These spray a ring of liquid, so their flow rates are lower than a comparably sized Full Stream Liquid Atomizing Spray Nozzle, which spray a full, filled-in circle.

Line Vac Conveyance Chart: Remember what I said above about the ability to speak confidently about our products? This new chart compiles decades of controlled in-house testing and details that some customers have shared with us on the performance of different Line Vac models with different materials they’ve been used to convey. While we can’t guarantee EXACT conveyance performance for any specific application, this is a VERY handy tool to get us “in the ballpark” and further increases our great ability to specify the right Air Operated Conveyor for your application.

ATEX Cabinet Cooler Systems: It was a pretty big deal when we introduced our HazLoc Cabinet Cooler Systems that are UL Classified for Class I Div 1, Class II Div 1, and Class III environments. And it WAS a big deal, in the United States & Canada. Now, we can offer the certification of hazardous location requirements, globally, for ATEX Zones 2 & 22. That’s ANOTHER big deal.

Speaking of big deals, come October, EXAIR will have been providing quiet, safe, and efficient compressed air products to industry for 40 years. Catalog 35 has all the products that we’ve been making since then, and everything we’ve added over the years. Click here to get one mailed out to you right away. If you’ve got questions about anything in our catalog, or how EXAIR can help you get the most out of your compressed air system, give me a call.

June’s PRESS RELEASE: New Ultrasonic Leak Detector For Energy Conservation

Published on by Tyler DanielLeave a comment

The generation of compressed air accounts for approximately 1/3 of all energy costs in an industrial facility. According to the Compressed Air Challenge, about 30% of that compressed air is lost through leaks. This means nearly 10% of your facility’s energy costs are simply wasted through poor connections, faulty air valves, improper installation, etc. In addition to simply wasting money, compressed air leaks can also contribute to a variety of other operating losses. A leak can cause a drop in system pressure. When this occurs, end users may not operate as efficiently and have an adverse effect on production. This same drop in system pressure will also cause the equipment to cycle on/off more often, shortening the life of your compressor and other equipment. If the leaks cause an issue in supply volume, it may lead to the belief that more compressor capacity is necessary, further increasing your operating costs.

To put leaks in perspective (assuming energy costs of .10/ kWh):

  • A $200/year leak cannot be felt or heard
  • A $800/year leak can be felt, but not heard
  • A $1,400/year leak can be felt and heard.

(Compressed Air Challenge)

If you walk through your facility, how many leaks can you hear? These are only the REALLY bad ones!!  So if we know that a large amount of compressed air is leaking, what do we do about it? A proper leak prevention plan is the key to success. Since these leaks are impossible to see and some cannot even be heard, you need a tool to help assist you. EXAIR’s NEW Model 9207 Ultrasonic Leak Detector is the right tool for the job. When compressed air leaks through a pipe, it creates an ultrasonic signature due to turbulence. While this sound is not always detectable by the human ear, this meter will allow you to locate leaks up to 20’ away.

High pressure gases create a high frequency turbulence when moving into an area with lower pressure. This results in an ultrasonic noise that is outside the range of human hearing. The ULD detects these signatures, creating an audible sound through the supplied headphones and indicating the intensity via the front-facing LED display as the meter is brought closer to the origin.

The ULD comes with attachments allowing you to filter out background noise in a typical industrial plant and includes “+” or “-“ buttons for fine-tuning the meter’s sensitivity settings. This new model offers heightened ability to detect leaks in hard-to-reach areas while also complying with IEC 613326-1 standard that designates its ability to operate in typical electromagnetic environments found within an industrial plant.

In almost any industrial plant, huge amounts of savings can be realized rather easily by implementing a leak protection program. EXAIR has the Model 9207 Ultrasonic Leak Detector ready to ship same-day from stock. Get yours on order today and start saving money!
