Small decreases in pressure are inevitable in any air compressor system, however significant pressure drop can lead to considerable problems. For those using air compression systems, it would be no secret that pressure drops can decrease performance, increase your power and operating costs, put more strain on your compressor meaning more regular maintenance, and even result in dirtier air in your workshop.

To help get the most out of your equipment, here’s a range of things you can do to minimise pressure drop in your air compressor system.

1. Re-Think your System Layout

Pressure drop can be caused by the air having to travel too far between your compressor and tools. Considering the layout of your piping, tools, and even where your compressor sits can ensure a tighter airflow. You’ll also want to consider the amount of connections your air must pass through – if some of these can be eliminated, you can further reduce the risk of pressure drop.

2.  Replace Hoses and Tubing

Leaking hoses and tubing can account for many instances of pressure drop. Kinks and folds in hoses and tubing can cause the material to crack, causing leaks. When checking your hoses and tubing, also make sure the ends are sealed and you’re not experiencing leaks around your end-use devices.

3. Check All Connection Points

In most compressed air systems, the air needs to pass through several connection points. These are common causes of leaks if not tightened correctly. Incorrectly sized connections can also cause leaks and subsequent pressure drops.

4. Clean Filters

The main job of a filter is to ensure a smooth, unhindered airflow through your system. If these are dirty or clogged, the air won’t move as freely as you want it to. This can result in a pressure drop at the end use point, so make sure filters are cleaned and replaced regularly.

5. Replace After-Cooler, Separators and Dryers

Any part of your compression system that has a job of treating air, such as after-coolers, separators and dryers can cause a pressure drop if not working correctly. Faulty air treatment components can cause a whole range of issues, so if any of these items need to be replaced, we recommend considering units that are rated for the lowest possible pressure drops at maximum operating capacity.

6. Reset your Regulators

Regulators should be adjusted regularly to ensure you’re not using excess energy to power your system. However, faulty regulators can also cause pressure drops and newer replacement units are designed for maximum pressure drop reduction.

7. Change Lubricators

A common cause of pressure drop in compressed air systems can be incorrectly sized lubricators. If your lubricators are sized for the average flow rate rather than the actual flow rate of your system, they won’t function correctly. Again, replacing them with correctly sized, newer lubricators that are rated for maximum pressure drop reduction is a way to make sure your system keeps running smoothly.
