Could Compressed Air Leaks Be Reducing Your System Capacity? 

When your compressed air system can no longer keep up with production demand, the first conclusion may be that you need to increase compressor capacity. 

But before investing in another air compressor, there is another question worth asking: 

 

Are you actually using all of the compressed air your system is producing? 

Compressed air leaks can quietly reduce the available capacity in your system. Your compressors then have to work harder, while less air remains available for your equipment and processes. 

Over time, these losses can contribute to pressure problems, higher energy costs, and the impression that your facility has outgrown the capacity of its existing equipment. 

Before adding another compressor, detecting and repairing leaks may allow you to recover some of the capacity you already have. 

 

Why Do Compressed Air Leaks Affect System Capacity? 

Every compressor can supply a limited amount of compressed air. Ideally, that air reaches the equipment and processes that need it. 

A leak diverts some of that air before it can even be used. 

A small leak may seem insignificant. However, in an industrial compressed air system, losses can occur at multiple points throughout the facility. Fittings, hoses, valves, couplings, and other components can all become sources of leaks. 

As these losses add up, your compressors still have to produce that air, but your operation does not benefit from using it. 

Your system may then have more difficulty maintaining the pressure and airflow required for your operations. 

 

The Impact of Higher Pressure on Your Energy Costs 

To compensate for pressure losses in a compressed air system, it can be tempting to increase operating pressure. However, this can lead to additional energy consumption. 

As a general guideline, increasing pressure by 2 psi can raise energy consumption by approximately 1% under certain conditions. Even a small increase in pressure can therefore have an impact on long-term operating costs without actually addressing the leaks causing the problem. 

 

Signs Leaks May Be Reducing Your Available Capacity 

A lack of capacity does not necessarily mean your compressor is too small. 

Here are some signs that may indicate it is time to take a closer look at the performance of your compressed air system: 

  • System pressure drops during periods of high demand 
  • Compressors run longer or more frequently than they used to 
  • Production equipment does not receive consistent air pressure 
  • Compressed air energy costs increase without a clear increase in production 
  • Additional compressors need to come online more often 
  • The system has difficulty keeping up during peak demand 
  • Compressors continue to run or cycle when production demand is low 

These symptoms can have several causes and do not automatically mean leaks are responsible. 

However, they are good reasons to evaluate the overall performance of your compressed air system. 

 

Do You Really Need Another Air Compressor? 

If your facility is short on compressed air, adding another compressor may eventually be the right solution, especially if production has increased beyond the true capacity of your existing system. 

However, adding equipment without understanding where your current compressed air is going can simply add capacity to an inefficient system. 

Imagine that your compressors are producing enough air to meet your facility’s needs, but some of that air is continuously escaping through leaks. 

Installing another compressor will increase the amount of available air, but it will not correct the existing losses. 

Identifying and repairing significant leaks first can help you better understand how much compressed air your facility actually needs. 

In some cases, this can help recover usable capacity that is already available in your system. 

In other cases, additional capacity may still be necessary, but your decision will then be based on a better understanding of your system’s actual demand. 

 

How Can Leak Detection Reveal Unused Capacity? 

Compressed air leaks are not always easy to detect during normal plant operations. 

In a noisy industrial environment, some leaks can go unnoticed while wasting compressed air every day. 

A professional compressed air leak detection program can identify where air is being lost throughout the system. 

At Compresseurs Québec, leak detection is performed using ultrasonic detection methods to evaluate the compressed air system quickly and effectively. 

Following the inspection, your team can receive information on: 

  • The precise location of identified leaks 
  • An estimate of the airflow associated with the leaks 
  • An estimate of the cost caused by compressed air losses 
  • The potential return on investment associated with repairing the leaks 

This information gives your maintenance team actionable data to determine which repairs should be prioritized.

 

Get More From the Compressed Air Capacity You Already Have 

When a compressed air system can no longer keep up with demand, purchasing another compressor should not necessarily be the first step. 

Understanding where your current capacity is going can help you make a more informed decision. 

Compresseurs Québec provides compressed air leak detection services in Montreal, the Greater Montreal area, and throughout Quebec to help businesses identify air losses, better understand their impact, and improve system performance. 

Before adding more capacity to your system, first determine whether some of the compressed air you are already producing is escaping through leaks.
