RCM for Air Compressors

Value rises with age. New Air Compressor Reliability & Maintenance units rarely show developing faults during the first 1000-3000 operating hours. The middle of the asset life (years 2-7 typically) is where RCM catches the most actionable findings. Late-life equipment — past the 40K-100K hours mark — shows higher fault frequency and benefits from tighter monitoring intervals than the program baseline.

asset-by-asset over months is the baseline. Adjust based on duty cycle: assets running near rated capacity 24/7 get tighter intervals; intermittent-duty units can stretch the interval by 50%. The general rule for Air Compressor Reliability & Maintenance specifically is that PdM cadence should be no more than half the dominant failure mode's P-F interval. For most Air Compressor Reliability & Maintenance populations that lands at quarterly oil sampling, monthly vibration.

Yes. RCM measurements use function/failure mode mapping which capture at the bearing housing, terminal box, or sampling point without disrupting operation. The Air Compressors stay online during the route. Only deep diagnostic work or repairs that follow from findings require taking the equipment offline.
