Short answer

An air compressor inspection checklist records checks on the receiver tank, pressure gauge, safety valve, drain, belts, hoses, filter, oil and electrical connections. Operators check it before each use on site; workshop compressors are typically checked daily or weekly with a monthly inspection, or as the manufacturer recommends. Regulation 224 of the model WHS Regulations requires pressure equipment to be inspected regularly by a competent person.

What is an air compressor inspection checklist?

An air compressor inspection checklist is a systematic list of checks performed on an air compressor to confirm it is safe, mechanically sound and fit for use. It is also called an air compressor checklist, a compressor inspection form or, for the tank on its own, an air receiver inspection checklist. It covers the receiver tank and pressure system, mechanical components (belts, hoses, filter, oil), electrical connections, safety devices (relief valve, pressure gauge) and the frame or mounting. The checklist is completed before each use or at scheduled intervals and provides documented evidence that the compressor has been inspected.

Air compressor receiver tanks are pressure equipment and carry risks from stored energy. Model WHS Regulation 224 requires pressure equipment at a workplace to be inspected on a regular basis by a competent person. AS 1210-2010 covers pressure-vessel design and construction, while the current AS/NZS 3788:2024 edition covers in-service inspection, including how the inspection strategy, scope and interval are determined. Registration and inspection duties vary by equipment and jurisdiction, so confirm the applicable state or territory requirements, manufacturer instructions and approved inspection plan. For electric compressors, check the current electrical in-service inspection requirements that apply to the equipment and work environment.

What to include in an air compressor inspection checklist

This air compressor inspection checklist covers 9 key areas:

  • Compressor details: asset ID, make/model, serial number, site/location, date, inspector name, type (portable/fixed) and current hours.
  • Tank and pressure system: receiver tank condition (corrosion, dents, damage), pressure rating plate legible, pressure gauge accuracy, safety/relief valve operation, condensate drain function and tank drain valve.
  • Mechanical and drive: drive belts (tension, wear, alignment), pulleys, motor mounting, vibration, coupling/shaft condition and belt guard in place.
  • Air system: air filter (clean, seated), hoses and fittings (cracks, leaks, clamps), regulators, outlets and quick-connect fittings.
  • Lubrication: oil level and condition, no leaks, oil type correct for compressor.
  • Electrical: power lead, plug, isolator, RCD test, motor condition, wiring and earthing.
  • Guards, frame and wheels: belt guard secure, wheel condition (portable units), frame/mounting, handle/tow bar, general cleanliness.
  • Overall result: Pass/Fail with a defect register for failed items.
  • Declaration and signatures: inspector sign-off and supervisor acknowledgement.

How to use this air compressor inspection checklist

  1. Record compressor details (asset ID, make/model, serial number, site, date, hours) at the top of the form.: Locate the data plate on the compressor to verify make, model and serial number. Read the hour meter and record the current reading. Note the site name or location code used in your asset register.
  2. Ensure the compressor is isolated and depressurised before starting the physical inspection (unless a check specifically requires the unit to be running).: Switch off the engine or motor and disconnect the power supply for electric units. Open the manual drain valve and confirm the receiver gauge reads zero. For portable units, chock the wheels to prevent movement during inspection.
  3. Work through each section in order - tank and pressure system, mechanical, air system, lubrication, electrical, then guards and frame. Mark Pass, Fail or N/A for each item.: Inspect the receiver tank for dents, corrosion or paint bubbling. Verify the pressure rating plate is legible. Test the safety relief valve by lifting the lever. Check belt tension by pressing the belt midpoint and confirming 10-15 mm deflection. Test the RCD by pressing the test button.
  4. For any Fail item, add a note describing the fault. Do not use the compressor until the fault has been assessed and rectified.: Describe the fault location, severity and any immediate risk. Attach a "Do Not Use" tag or lockout device to the compressor if a critical safety item fails. Escalate pressure vessel defects to a competent person for assessment under AS 3788.
  5. Drain the condensate from the receiver tank after the inspection (or confirm it was drained).: Open the drain valve at the lowest point of the receiver tank and allow all water and oil condensate to discharge into a suitable container. Dispose of condensate according to your site environmental management plan, as it may contain oil residue.
  6. Complete the overall result (Pass/Fail) and record all failed items in the defects register.: Mark the checklist as Pass only if every critical item passes. Transfer all failed items to the defect register with a unique reference number, assigned owner and due date for rectification.
  7. Sign and date the declaration. The supervisor or reviewer signs the acknowledgement section.: The inspector signs to confirm the inspection was performed thoroughly and accurately. The supervisor reviews the findings, approves or escalates defect actions, and countersigns within 24 hours of the inspection.

How often should you complete this checklist?

Portable air compressors used on construction sites should be inspected before each use or at the start of each shift. Fixed workshop compressors are typically checked daily or weekly, with more thorough inspections monthly. Condensate should be drained from the receiver tank after every use session or at least daily.

Beyond routine pre-use checks, pressure vessels are subject to in-service inspection requirements under AS/NZS 3788 and state/territory WHS regulations, including external visual inspections, internal inspections and hydrostatic testing at intervals determined by the equipment's hazard level. Safety/relief valves should be tested or replaced at intervals specified by the manufacturer. Follow the most stringent applicable requirement.

Frequently asked questions

An air compressor inspection checklist should cover: receiver tank condition (corrosion, damage, pressure rating plate), pressure gauge accuracy, safety/relief valve operation, condensate drain function, drive belts (tension, wear, alignment), hoses and fittings (cracks, leaks, clamps), air filter (clean, seated correctly), oil level and condition, electrical connections (leads, plug, isolator, RCD), guards and covers (belt guard, moving parts), and wheels/frame/mounting (secure, no cracks, stable). Include space for overall result, defects and sign-off.

Portable compressors on construction sites are usually checked before each use or at the start of each shift, and fixed workshop compressors daily or weekly with a more thorough monthly check. Where the model WHS Regulations apply, which is every state and territory except Victoria, regulation 213 requires plant to be inspected by a competent person, following the manufacturer's recommendations, or a competent person's recommendations if there are none, and annually if neither is reasonably practicable. Regulation 224 adds that pressure equipment must be inspected on a regular basis by a competent person.

In every state and territory except Victoria, where the model WHS laws have not been implemented, yes. The receiver tank is a pressure vessel, which the model WHS Regulations treat as pressure equipment, and regulation 224 requires pressure equipment at a workplace to be inspected on a regular basis by a competent person. Regulation 213 also requires the maintenance, inspection and, if necessary, testing of plant to be carried out by a competent person. Whether the receiver must be registered depends on its hazard level and the exceptions in Schedule 5, and AS 3788:2024 covers in-service inspection.

Common faults include: moisture build-up in the receiver tank (not draining condensate regularly), worn or slipping belts, blocked air filters reducing efficiency, oil leaks or low oil levels, faulty pressure gauges giving inaccurate readings, seized or leaking safety/relief valves, damaged hoses or fittings, and electrical faults (damaged leads, tripped RCDs). Catching these early prevents breakdowns, reduces fire risk and avoids pressure vessel incidents.

If you want to schedule compressor inspections digitally, track inspection history per asset and receive automatic reminders when inspections are due, MapTrack can do that. Book a demo to see how.

OSHA 29 CFR 1910.169 covers compressed air receivers. Each receiver needs a drain pipe and valve at its lowest point, and the drain must be opened and the receiver completely drained often enough to stop excessive amounts of liquid building up. Every receiver needs a readable pressure gauge and one or more spring-loaded safety valves, with no valve of any type between the receiver and its safety valves, and all safety valves must be tested frequently and at regular intervals. Drains, handholes and manholes must be easy to reach.

Often enough to stop excessive water and oil building up in the receiver. OSHA 29 CFR 1910.169 requires the drain valve to be opened and the receiver completely drained frequently, at intervals that prevent excessive liquid accumulating, and it allows automatic traps in addition to the drain valve. This checklist treats draining as an after-use or at least daily task. The condensate can contain oil residue, so collect it and dispose of it under your site environmental plan.

It depends on the size of the receiver. In Great Britain, regulation 8 of the Pressure Systems Safety Regulations 2000 stops the user of an installed system, or the owner of a mobile one, from operating it without a written scheme for periodic examination by a competent person of its protective devices and of any pressure vessel or pipework where a defect could cause danger. Compressed air above 0.5 bar is a relevant fluid, and for it Schedule 1 lifts that duty where each vessel's pressure in bar multiplied by its internal volume in litres is less than 250. Northern Ireland has its own 2004 regulations.
