Why Is My Compressor Not Pressurizing? Common Causes and Solutions
Has your compressor stopped working properly and isn't building pressure? This is one of the most common problems reported by users of piston and screw compressors. In this article, we explain what might be causing the problem and how you can fix it.
1. Dirty air filter
A dirty filter restricts airflow, making it difficult to build up pressure. Regular filter replacement is essential – ideally every 500 hours of operation.
Solution: Check and replace the air filter. If necessary, order genuine parts from us – we offer a wide selection for various compressor models.
2. Damaged suction or discharge valve
Valves are responsible for ensuring air flows in the correct direction. If they are damaged, air can leak out of the cylinder.
Solution: Have your valves diagnosed. At Czemar.pl, we provide fast service for piston and screw valves.
3. Leak in the system
Leaks can occur in lines, valves, or the tank. Air escapes before it reaches the desired pressure.
Solution: Perform a leak test or use our compressed air system inspection service.
4. Wear of piston rings (in piston compressors)
If the piston rings are worn, the compressor loses compression and does not build up the proper pressure.
Solution: Replacing the rings is part of a standard compressor overhaul. We offer repairs and overhauls with a warranty.
5. Problems with the electric motor
Too low engine speed, overheating or phase loss can affect compressor performance.
Solution: Order an electrical inspection – our service will check the condition of the motor, contactors and protections.
