Conserve Air with the Electronic Flow Control

Published on by John BallLeave a comment

A system with gaps in the process could be a candidate for saving compressed air.  This is a hidden profit-reducing culprit that is not well recognized.  I would like to correlate it to the refrigerator light turning off.  When it is not needed, then why have it on?  If your system has gaps, you should turn off the compressed air during these times to save money.  In this blog, I will cover the Electronic Flow Control, or EFC, to help optimize your compressed air system.

EXAIR’s Electronic Flow Control provides precise timing control with a user-friendly module.  The timing is selectable from milliseconds to hours to optimize the on/off time of the solenoids.  They are CE and RoHS compliant.  The input power can range from 85 VAC to 264 VAC at 50 or 60 Hz.  It does come standard with a 120VAC Type B US plug or a NEMA 5-15P.  For other types of connections, please follow your local electrical standards.  The enclosure is NEMA 4 (IP 66) with a temperature rating from -13oF to 131oF (-25oC to 55oC).  The design of the EFC enclosure makes it very easy to mount onto your system. 

The EFC uses a photoelectric sensor to initiate the timing circuit.  It has a Light and Dark mode as well as a sensing range.  It will be factory set at 12” (305 mm), and it can be adjusted up to 3.3 feet (1 meter) with the sensitivity adjuster.  The sensor has a green light which means that the sensor has power, and an amber light which means that the sensor is triggered.  It comes standard with a 16.5 feet (5 meter) sensor cable. 

The EFC has seven timing selections.  The factory setting is set to R for an “Off” Delay, which operates when an object is detected. It will open the solenoid valve immediately and remain open for a set amount of time.  The other modes are “On” Delay, Single Shot – Rising Edge, Single Shot – Falling Edge, “On” Delay with control input, Single Shot – Rising Edge Supply voltage, and Clock Interval.    

EXAIR offers four different sized solenoid valves, ranging from ¼” NPT to 1” NPT sizes.  So, we can handle products that utilize high demands of compressed air.  We also can offer a dual solenoid type to operate two systems at the same time. 

The customers that purchase the Electronic Flow Control are people that need to improve their process for maximum savings, do not wish to purchase a PLC, have I/O boards that are loaded, or do not wish to contract an outside programmer.  As I mentioned above, they are simple to use.  If you have any questions about the EFC or wish to see the ROI, EXAIR has Application Engineers that can help you.

Finding and Fixing Compressed Air Leaks

Published on by jasonkirbyLeave a comment

One of the most significant challenges facing compressed air systems is the presence of leaks. The subtle hissing sound emanating from the pipelines can lead to substantial financial losses for your company. A university study revealed that in poorly maintained systems, approximately 30% of compressor capacity is wasted due to air leaks. Unfortunately, many organizations neglect to implement leak prevention programs, resulting in inefficient systems. To quantify the impact, an inaudible leak can cost as much as $130 annually, and this is just for a single leak within extensive compressed air lines. For audible leaks, the accompanying chart illustrates the potential financial waste based on the size of the leak. Unlike hydraulic systems, compressed air leaks do not create visible messes, making them harder to detect and requiring alternative methods for identification.

Leaks commonly occur at threaded fittings, connections, hoses, and pneumatic components such as valves, regulators, and drains. EXAIR’s Optimization products are specifically designed to enhance the efficiency of your compressed air system, with leak elimination being the most effective strategy. Utilizing Ultrasonic Leak Detectors allows for the identification of air leaks, while Digital Flowmeters enable monitoring of system flow, particularly during non-production periods. By incorporating these tools into a leak prevention program, you can significantly improve your ability to detect and address leaks, ensuring your compressed air system operates at peak performance.

When a leak occurs, it produces ultrasonic sounds due to turbulence, often at frequencies above 20 kHz, which are inaudible to the human ear. The EXAIR Ultrasonic Leak Detector, model 9207, is designed to detect these frequencies and convert them into audible sounds through a technique known as “heterodyning.” This device features a signal strength indicator and a bar graph display, enabling users to identify even the smallest leaks. It includes two attachments: a parabolic microphone for locating leaks from distances of up to 20 feet, and a tube attachment for pinpointing the exact source of a leak among multiple connections within a pipe. Once identified, leaks can be marked for repair.

Digital Flowmeters enable continuous monitoring for waste, particularly in pneumatic systems where air leaks can arise unexpectedly. By isolating different sections of your system, you can conduct systematic checks and analyze flow readings with the Digital Flowmeter. Additionally, tracking results over time can provide valuable insights into system performance. We also offer a USB Datalogger option, allowing you to set specific time intervals for recording air flows. After capturing the data, you can connect the USB to your computer and utilize downloadable software to review the information, which can also be exported to an Excel spreadsheet for further analysis. If you notice a consistent upward trend in flow readings for a particular process, you can employ an Ultrasonic Leak Detector to identify the presence and location of any leaks. Furthermore, the Digital Flow Meter serves as a proactive tool, helping to indicate potential failures in your pneumatic system by analyzing trends in the readings over time.

If you have questions about finding and fixing compressed air leaks, or anything regarding EXAIR and our products, please do not hesitate to reach out.

6 STEPS: [Step Four] Turn it off when not in use.

Published on by Jordan T ShouseLeave a comment

Turning off compressed air when it’s not in use is one of the fastest ways to reduce energy costs, extend equipment life, and improve overall efficiency. When paired with efficient air products and proper controls, the savings can be substantial and immediate.

Compressed air is valuable. Treat it that way. Here are some helpful ways to use it when you need it!

Start by walking the plant floor and identifying applications that run continuously, especially during breaks, shift changes, or downtime. Common culprits include open blow offs, cooling air left running, or vacuum systems operating without parts present. If air is flowing without adding value, it’s costing you money. So let’s find ways to turn it off.

  1. Tie Air Use to Production Activity
    • Compressed air should only be used when production is active. Connecting air supply to machine cycles, sensors, or PLC controls ensures air flows only when parts are present or a process is occurring. Automating on/off control not only reduces waste but also improves consistency and repeatability.
  2. Use Solenoid Valves for Automatic Shutoff
    • Solenoid valves are an effective way to shut off air when equipment is idle. When integrated into machine logic or timers, they prevent air from flowing during downtime, nights, and weekends. This is especially effective for blow off and cooling applications that don’t require constant air.
  3. Replace Open Blow offs with Efficient Nozzles
    • Open pipes and tubing waste enormous amounts of compressed air. High-efficiency air nozzles and air knives are engineered to amplify airflow while consuming significantly less compressed air. Upgrading these devices not only lowers air consumption but also improves safety by reducing noise levels.
  4. Monitor, Audit, and Reinforce
    • Turning the air off once isn’t enough, it needs to become part of the culture. Regular air audits, flow monitoring, and team accountability help ensure improvements stick. Encouraging operators and maintenance teams to report unnecessary air usage creates long-term savings and reinforces best practices.

Turning compressed air off when it’s not in use is a powerful first step—but real, lasting savings come from pairing good habits with the right technology. That’s where EXAIR solutions make the difference.

EXAIR Engineered Air Nozzles replace inefficient open pipes and tubing, delivering the force you need while dramatically reducing air consumption and noise. EXAIR Air Knives provide uniform, high-velocity airflow for drying, cooling, and cleaning—using far less compressed air than homemade blow offs. When higher airflow or vacuum is required, EXAIR Air Amplifiers generate powerful output without additional energy input.

To ensure those savings are measured and maintained, EXAIR Flow Meters give you real-time visibility into compressed air usage, helping you identify waste, verify improvements, and build accountability into your process.

Compressed air doesn’t have to be a hidden cost. With smart shutdown practices and proven EXAIR products, you can turn wasted air into measurable savings—every shift, every day.

Published on by Al WooffittLeave a comment

Here at EXAIR we are very proud of our Intelligent Compressed Air Products. We have spent a lot of time discussing their many benefits, including their efficiency, the fact that many have no moving parts, little to no maintenance, meeting or exceeding OSHA safety standards for noise or dead end pressure. One thing we don’t talk as much about is the accessories that go along with and complement our products. Several of these accessory items are the reason why our compressed air products can boast about having little to no maintenance, or reduced noise levels. In this blog I want to cover some of these unsung heroes.

From left to right, a few value-added accessories for your Vortex Tube: Hot Muffler, Cold Muffler, Automatic Drain Filter Separator, Oil Removal Filter, and Solenoid Valve/Thermostat Kit.

Some of the most popular accessories we offer are our compressed air Filters and Regulators. We suggest using these with all our products (or even with ones that aren’t ours).

The Filter Separator is designed to remove moisture, dirt, and rust from your compressed air system. The 5-micron filter element ensures that contaminants don’t clog or harm your compressed air equipment.

An Oil Removal Filter (which should always be installed after our Filter Separator) provides even more precise filtration by getting rid of oil and solid particles with a 0.03-micron element.

Our Pressure Regulators let you choose the operating pressure. At EXAIR, we always advise running at the lowest pressure necessary to complete the task. Pressure Regulators help you achieve that, reducing unnecessary air usage and fine-tuning the performance of EXAIR products for your specific application.

We have some accessories designed specifically for certain products. For our Line Vacs, there’s the Line Vac Hose. You can also find Thermostats and Solenoid Valves that work great with our Cabinet Coolers, and if you’re using Vortex Tubes, we suggest checking out our Mufflers.

When it comes to our Air Knives, we offer a variety of fantastic options:

If you’re looking for a simple and dependable way to mount your Air Knife, our Universal Air Knife Mounting System is just what you need.
