Preventive maintenance
Daily
  • Check fluid level in sight glass at running temp
  • Listen for unusual noise / vibration
  • Check discharge pressure & temperature vs baseline
  • Verify condensate drain function
  • Log package amps if metered
Weekly
  • Blow down receiver and drain traps
  • Check for oil carryover at first drop leg
  • Inspect for fluid or air leaks around airend and separator tank
  • Verify safety valve is not weeping
Every 2,000 hr / 6 mo
  • Change fluid filter
  • Change air filter (or sooner per ΔP)
  • Sample fluid for TAN / metals / water
  • Clean cooler exterior with low-pressure air (never > 30 psi against fins)
Every 4,000 hr / 12 mo
  • Change separator element
  • Change fluid
  • Inspect scavenge line & orifice for coking
  • Check coupling / belt alignment & wear
  • Torque electrical lugs to spec (typ. 45–75 in-lb #4–2/0 AWG)
Every 8,000 hr
  • Rebuild inlet valve
  • Rebuild minimum-pressure check valve
  • Regrease or replace motor bearings per OEM interval
  • Verify safety valve setpoint against gauge
Common faults & first checks
  • High air temp on cooler pluggage
  • Sep ΔP at 4k hr
