Troubleshooting

A reliable compressed air system is the backbone of your production. When pressure drops, oil leaks, the compressor overheats or the machine suddenly goes silent, every minute costs money. Our experienced technicians recognize the symptoms immediately and bring your system back to peak performance – often the same day.

Common Problems – and Why They Occur

1. The compressor fails to build sufficient pressure Pressure never reaches the desired level, tools become sluggish and production slows down. Frequently caused by dirty/clogged air intake filter, leaks in the pipe system (commonly 20–35% energy waste!), worn intake or unloading valves, low oil level or leaking piston rings/seals. The result? The compressor runs constantly without delivering – expensive electricity bills and unnecessary wear.

2. The compressor won’t start at all Complete silence where there should be a steady hum. Frustrating and expensive. The most common culprits are faulty pressure switch, burnt contacts, tripped fuse/circuit breaker, defective contactor, phase failure or simply a switched-off main power breaker. In the worst cases, the motor has overheated and tripped its thermal protection.

3. Overheating – compressor shuts down or trips on safety High temperature causes shutdown or alarm. Often due to dirty cooler, clogged air intake, low oil level, faulty thermostatic valve, blocked oil filter or simply the compressor operating in an environment with insufficient ventilation. The consequence is reduced service life and risk of serious damage to screw element or electric motor.

4. Abnormal noises – knocking, squealing or whining The compressor doesn’t sound right – a clear warning sign. Knocking can come from worn bearings or loose connecting rods, whining from leaking valves or broken belt, scraping from insufficient lubrication. If ignored, these noises often lead to complete breakdown within a few weeks.

5. Air leaking – pressure drops quickly when the machine is off The pressure gauge falls rapidly after shutdown. Almost always hidden leaks in couplings, hoses, quick-connect fittings, faulty blow-off valves or cracked tanks. A single large leak can cost tens of thousands of kronor per year in pure energy loss.

6. Condensate issues – water in the compressed air Tools rust, paintwork bubbles, products are ruined. Frequently caused by clogged condensate drain/automatic drain, defective refrigeration dryer, faulty aftercooler or simply that the system is undersized for the current humidity level.
