Pro Tips for Effective Air Compressor Inspection
Inspect Before Starting: Always perform visual inspections with the compressor turned off and cooled down. This prevents potential injuries and allows for accurate fluid level checks.
Listen During Operation: After visual inspection, run the compressor briefly and listen for unusual sounds like knocking, rattling, or excessive vibration which can indicate internal problems.
Check Output Air Quality: Periodically test the air quality by running the compressor and feeling for moisture or oil in the output air, which could indicate internal issues with the air/oil separator or moisture trap.
