Compressed Air System Inspection

Inspection template for evaluating compressed air system safety, maintenance, and air quality, including receiver tank condition, pressure relief devices, drains, compressor performance, and contamination controls.

Inspection Details and System Identification

• System location and asset ID documented
  Record the building, room, line, or area, plus the compressor or system asset identifier.
• Inspection date and inspector name recorded
  Capture the date/time of inspection and the responsible inspector.
• System type identified
  Identify the compressed air system configuration being inspected.
• Inspection scope confirmed against SOP or PM checklist
  Verify the inspection is being performed against the current site SOP, preventive maintenance checklist, or manufacturer guidance.
• Any recent changes, repairs, or abnormal events noted
  Document recent maintenance, alarms, shutdowns, leaks, contamination events, or process changes that may affect the inspection.

Compressor and Operating Performance

• Compressor starts, runs, and cycles normally
  Verify the unit starts without unusual delay, runs smoothly, and cycles within expected operating behavior.
• Operating pressure is within the approved range
  Measure actual discharge or system pressure and compare it to the approved operating range.
• Unusual noise, vibration, or overheating observed
  Check for abnormal mechanical noise, excessive vibration, hot surfaces, or signs of overheating.
• Oil level, lubricant condition, or oil carryover acceptable
  For lubricated systems, verify lubricant level and condition are within manufacturer limits and there is no visible excessive oil carryover.
• Belts, guards, couplings, and drive components in good condition
  Inspect accessible drive components for wear, looseness, missing guards, or damage.

Receiver Tank and Pressure Relief Devices

• Receiver tank exterior free of corrosion, dents, or visible damage
  Check the receiver tank shell, welds, supports, and base for corrosion, deformation, leaks, or other visible damage.
• Pressure relief device present, accessible, and properly tagged
  Verify a pressure relief device is installed, accessible, and identified per site requirements.
• Pressure relief device setpoint verified
  Record the relief device setpoint and confirm it matches the approved system design or manufacturer specification.
• Receiver tank drain functioning and free of blockage
  Verify manual or automatic drains are operational and removing condensate without blockage, leakage, or excessive accumulation.
• Tank gauge and fittings readable and intact
  Check that pressure gauges, valves, and visible fittings are intact, readable, and not leaking.

Air Quality, Filtration, and Contamination Controls

• Filters installed and service indicators within acceptable range
  Verify intake, coalescing, particulate, or dryer filters are installed as required and service indicators do not show end-of-life or bypass conditions.
• Moisture, oil mist, or particulate contamination observed at point of use
  Check hoses, outlets, and point-of-use equipment for visible contamination, excessive moisture, or oil carryover.
• Dryer performance acceptable
  Verify the air dryer is operating normally and delivering air within the site's required dryness specification.
• Condensate disposal method controlled and compliant with site procedure
  Confirm condensate is collected, treated, or disposed of according to site environmental and maintenance procedures.

Safety, Housekeeping, and Compliance

• Equipment area clear of obstructions and slip hazards
  Check that access to compressors, tanks, drains, and valves is unobstructed and that condensate or oil has not created a slip hazard.
• Warning labels, operating instructions, and pressure markings visible
  Verify required labels, pressure markings, and operating instructions are legible and in place.
• Lockout-tagout isolation points identified
  Confirm energy isolation points are identified and accessible for maintenance in accordance with OSHA 1910.147.
• Electrical and mechanical guards in place
  Check that guards and covers protecting moving or energized parts are installed and secure.
• Corrective actions documented for all deficiencies
  List each deficiency or non-conformance, the immediate control, and the responsible owner for follow-up.
