Tech Tips: Maintenance Checklist

Air Compressor Maintenance Checklist

If this section doesn't quite address what you want to know, feel free to email us or call us at any of our three, convenient locations for assistance. Our expert staff and technicians welcome the opportunity to help you keep your system operating at peak performance.

The following is a good start for basic maintenance of your air compressor.

  • Inlet Filter Cartridges – Inspect and clean or replace as per manufacturer specifications. Required frequency is often related to operating conditions. Dirty filters increase energy consumption.
  • Drain Traps – Clean out debris and check operation periodically.
  • Compressor Lubricant Level – Inspect daily and top-off or replace as per manufacturer specifications. Change lubricant filter as per manufacturer specifications.
  • Air Lubricant Separator (for lubricant-injected rotary screw compressors) – Change as per manufacturer specifications or when pressure drop exceeds 10 psid, whichever is less.
  • Lubricant Selection – Select compressor and electric motor lubricant as per manufacturer specifications.
  • Belt Condition – Check belts for wear and check/adjust tension as per manufacturer specifications.
  • Operating Temperature – Verify that operating temperature is per manufacturer specifications.
  • Air Line Filters – Replace particulate and lubricant removal elements when pressure drop exceeds 2 to 3 psid. Inspect all elements at least annually regardless of pressure drop indication.
  • Water Cooling System – For water-cooled systems, check water quality (especially pH and total dissolved solids), flow and temperature, and clean/replace filters and heat exchangers as per manufacturers specifications.
  • System Leaks – Check lines (especially joints), fittings, clamps, valves, hoses, disconnects, regulators, filters, lubricators, gauge connections and end-use equipment for leaks.
  • System Cleanliness – Check system for compressor and motor lubricant leaks and cleanliness.
