How To Find Leak In The Air Compressor

Air compressor leaks are a common problem that can lead to wasted energy and increased costs. In fact, on average, 20-30% of the compressed air used in a manufacturing plant is wasted as leaked air. Therefore, it’s essential to detect and fix air compressor leaks as soon as possible to prevent losses.

Here are some steps you can take to find a leak in your air compressor system:

1. Listen for hissing sounds
   Walk around your air compressor and listen for a hissing sound. This could indicate a leak in the system. However, if you work in a loud factory or plant, this method may not be effective.
2. Use an ultrasonic acoustic detector
   The most reliable tool for detecting air compressor or air line leaks is an ultrasonic acoustic detector. These detectors can recognize the high-frequency hissing sounds associated with air leaks. The device consists of audio filters, microphones, amplifiers, and visual indicators or headphones that help in the detection of air leaks.
   These devices detect turbulent air flow caused by a leak somewhere in the line. This air creates a noise that is detected by the ultrasonic acoustic detector. These devices are ideal for noisy facilities because they can filter out background noise to accurately detect a leak.
3. Check the supply shut-off valve
   Locate the supply shut-off valve to the facility and turn it off. Let the compressor build up to set pressure and observe the pressure gauge over a period of time. If the pressure maintains, your compressor system is leak-free. If the pressure drops off, there is a leak somewhere in the system.
4. Inspect common areas for leaks
   The most common areas for leaks in an air compressor system include couplings, fittings, pipe sections, hoses, joints, drains, and external unloader valves. Tighten any loose fittings or valves and replace any damaged hoses or pipes.

Preventing air compressor leaks

Prevention is always better than cure. Therefore, regular maintenance of your air compressor system can prevent leaks from occurring in the first place. Here are some tips for preventing air compressor leaks:

1. Regularly Check And Replace Worn Out Parts
   Check hoses, couplings, and valves regularly for any signs of wear and tear. Replace any worn out or damaged parts to prevent leaks from occurring.
2. Ensure Proper Lubrication
   Make sure that moving parts are properly lubricated to prevent them from wearing out and causing leaks.
3. Clean Air Filters Regularly
   Regularly clean air filters to prevent blockages that can cause leaks in the system.
4. Implement A Leak Detection Program
   Implement a leak detection program and conduct regular audits to identify and fix any leaks promptly.

Air compressor leaks can lead to wasted energy, increased costs, and downtime. By following the steps outlined above, you can detect and fix air compressor leaks promptly. Additionally, regularly maintaining your air compressor system and implementing a leak detection program can help prevent leaks from occurring in the first place. By taking these steps, you can save energy, money, and time while extending the lifespan of your air compressor system.
