VFD compressors need care for both the mechanical side and the drive electronics. A few common mistakes cause most early failures.
Ignoring the Drive Cooling
Dust on the heatsink and a blocked fan overheat the converter. Keep the electrical cabinet clean and cool.
Wrong Filter or Oil Intervals
Extended intervals or non-genuine parts compromise the air end and separator.
Frequent Hard Stops
Always follow the normal stop sequence; sudden power cuts stress the drive and bearings.
Neglecting Parameter Checks
Do not alter drive parameters without confirming the correct values for the machine.
