In modern industrial environments, compressed air is a critical energy source, powering machinery, automation systems, welding robots, and powder coating equipment. However, compressed air systems often suffer from air leaks—a silent yet costly issue that leads to energy waste, increased operational costs, and unplanned downtime.

One of the world’s leading manufacturers recently shared their experience with managing air leaks in a 13,935.5 m² facility, where a 200 HP compressor powers approximately 400 air-operated tools and systems.

“We use compressed air everywhere in our plant—from pneumatic actuators and welding robots to laser cutters and powder coating equipment,” said the company president.

🎯 The Challenge: Air Leaks Are Hard to Detect and Costly

Due to years of plant mergers and integration of older systems, the likelihood of air leaks increased significantly. These leaks force compressors to run harder and longer, driving up energy consumption and maintenance costs.

In a noisy production environment, locating leaks by ear becomes nearly impossible. The maintenance team used to wait until after working hours or during scheduled downtime to listen for leaks.

“We typically wait until the building is quiet—after a shift ends or during maintenance windows—and try to hear leaks manually. We also spray soapy water on suspected areas and look for bubbles,” said a maintenance supervisor.

This manual approach requires maintenance staff to be physically close to potential leak points, which may be located overhead or in difficult-to-reach areas. Even ultrasonic leak detectors, while effective, require trained technicians and considerable time to cover a full facility.

🔍 The Solution: “See” the Sound with Fluke’s Acoustic Imaging Technology

To address these limitations, Fluke introduced the team to the Fluke ii900 Industrial Acoustic Imager, a powerful tool capable of:

• Detecting leaks up to 50 meters away
• Functioning effectively in noisy environments
• Generating real-time SoundMap™ visuals of leak locations
• Overlaying sound frequency data on visual images for clarity
• Refreshing data 10–20 times per second for real-time feedback

Initially skeptical, the plant’s maintenance crew agreed to test the ii900. Over the course of a single 8-hour shift, two technicians used two ii900 devices to scan the entire compressed air system throughout the plant.

The results were eye-opening: 143 leaks were detected in just one day, ranging from large to minute leaks that were otherwise impossible to detect.

“I was unsure about some spots the ii900 flagged, so I double-checked with soapy water—and it was right. There was a leak exactly where it indicated,” said a technician.

🚀 Detecting Hard-to-Reach Leaks Without Stopping Operations

One notable detection was an overhead leak about 8 meters above ground—an area previously too difficult or dangerous to inspect during operating hours. With the ii900, technicians were able to locate it effortlessly from the ground.

“I was amazed at how easily I could walk down the aisle, point the Fluke acoustic imager upward, and quickly find the leak,” said the maintenance manager.

💡 Real-World Benefits: Time Savings, Energy Efficiency, and Lower Labor Costs

The benefits of using Fluke ii900 go beyond leak detection. By enabling quick, accurate scans during regular shifts, the tool eliminates the need for overtime or after-hours inspections.

“After identifying and fixing most of the leaks, we now monitor the plant routinely during normal hours,” the maintenance director explained.

In addition to saving labor time, the team now reduces wear on air compressors and avoids unnecessary energy loss. The ability to capture and share leak images helps direct repair teams precisely to the problem area.

“With visual leak images, our repair teams know exactly where to go. That alone saves us significant labor and energy costs,” he added.

✅ Conclusion: Fluke ii900 is a Game-Changer for Compressed Air Maintenance

Air leaks are common but often overlooked issues in industrial plants. With the Fluke ii900 Industrial Acoustic Imager, maintenance teams can now visualize sound, locate leaks efficiently, and take corrective action faster—without interrupting operations.
