Industrial Air Compressor Maintenance Tips

Proper maintenance and routine inspections of your compressed air system help prevent costly downtime and emergency repairs. These preventative maintenance tasks may be performed by in-house technicians or by companies, like C&B, that offer compressed air services.

Air Compressor Maintenance and Inspection Checklists

The operator’s manual for your compressor should always be your first point of reference for service recommendations and maintenance intervals. The following are general air compressor maintenance tips based on the typical intervals we see for these services. Not all may apply to your compressor type, and your service intervals may be more or less frequent.

  • Air Filter – Change the air filter every 1000 hours or as needed. Check weekly and clean to remove any dust and debris.
  • Oil Filter – Change every 1000 hours or as needed.
  • Lubricant – Check level daily. Change every 4000 to 8000 hours (depending on type) or as required.
  • Separator Element – Change out when the lubricant is changed.
  • Motor Bearings – Grease every 2000 hours or as needed.
  • Belts – Check weekly for wear and tension. Adjust tension and replace belts as needed.
  • Intake Vents – Check weekly and clean as needed.

Regular inspections will help spot potential problems and keep your compressed air system running efficiently and cost-effectively. The following is a typical inspection checklist:

  1. Overall cleanliness of the unit
  2. Temperatures
  3. Pressures
  4. Voltage
  5. Amps
  6. Oil Level
  7. Vibration
  8. Belt tension and condition
  9. Check moisture drains for proper operation
  10. Check coolers for dirt accumulation and clean if needed
  11. Check coolers for dirt accumulation and clean if needed
  12. Controller settings
  13. Check for proper loading, unloading and modulation
  14. Check for oil and air leaks
  15. Operational check of compressed air dryer

Keeping inspection and service logs will promote accountability and provide insight into the condition of your compressed air equipment.

The Importance of Compressed Air Audits

Along with preventative maintenance, a compressed air audit can help you lower energy costs, reduce downtime, lessen equipment wear, and keep your system running at peak efficiency.

During an audit, a technician taps into the main air lines and measures cfm, pressure and amp load over the course of several days, during different shifts. Measuring the compressed air usage helps save the supply of air at point of use, and helps identify leaks in the system. Annual or bi-annual audits can help you keep on top of costly leaks and prioritize repairs.

The goal is to identify supply side compressed air equipment and, if possible, use existing equipment to reduce energy costs and improve air quality. This may include proper setting of the controls, reducing leakage at auto drains, properly sequencing multiple units, and reducing artificial air demand.
