Here are some great Air Compressor Trouble Shooting Tips
to help you or anyone providing the regular maintenance for your compressed air system.
Below are listed several very common problems, their probable cause and some usual remedies for the trouble.
Of course, there can be multiple problems and unique circumstances to every compressor issue…but these tend to solve the most common situations.
Leaks in distribution piping – Check lines, connections and valves for leaks
Clogged filter elements – Clean or replace filter elements
Fouled dryer heat exchanger – Clean heat exchanger
Low pressure at compressor discharge
See BelowFor systems with modulating load controls, improper adjustment of air capacity system:
Follow manufacturer’s recommendation for adjustment of air capacity system
Worn or broken valves Improper air pressure switch setting: Check valves and repair or replace as required
Follow manufacturer’s recommendations for setting air pressure switch
Improper air pressure switch setting: Follow manufacturer’s recommendations for setting air pressure switch
Failed condensate traps: Clean, repair, or replace the trap
Failed or undersized compressed air dryer: Repair or replace dryer. If you do not have a Compressed Air Dryer, consider adding this equipment.
Faulty air/oil separation: Check air/oil separation system; change separator element
Compressor oil level too high: Follow manufacturer’s recommendation for proper oil level
In the absence of liquid water, normal aging of the air lines: Install filters at point of use
System idling too much: For multiple compressor system: consider sequencing controls to minimize compressor idle time
Adjust idle time according to manufacturer’s recommendations
Improper pressure switch setting: Readjust according to manufacturer’s recommendations
Restricted airflow: Clean cooler exterior and check inlet filter mats
Check water flow, pressure, and quality; clean heat exchanger as needed
Check compressor oil level, add oil as required
Remove restriction, replace parts as required
Improper ventilation to compressor; check with manufacturer to determine maximum operating temperature.
