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.
