What is a air compressor service log book?

An air compressor service log book is a running record of every service, inspection and repair on a reciprocating or rotary screw air compressor and its air receiver over the life of the unit. Each entry captures the date, the running hours, the work done, the compressor oil, air and oil filters, belts and separator element replaced, the state of the receiver and its drain, and the check of the pressure safety valve. It is a chronological history that stays with the machine, so anyone can see when it was last serviced, what was done and when the next service falls due, rather than relying on scattered sheets or memory.

A compressor is often the utility that a whole workshop, plant or process depends on, and it stores energy in a pressurised air receiver, which makes the receiver a pressure vessel with its own inspection duties. AS/NZS 3788:2024 covers the in service inspection of pressure equipment, and its hazard level under AS 4343-2014 drives whether the receiver must be registered with the regulator and how often it is inspected. A poorly maintained receiver with a corroded shell or a stuck safety valve is a genuine explosion risk. A disciplined service log keeps the compressor reliable, records the receiver and safety valve checks needed for pressure equipment, and supports the duty to maintain plant under the model Work Health and Safety (WHS) Regulations (mirrored in each state and territory except Victoria, which uses the OHS Regulations 2017 (Vic)) and the asset management discipline of ISO 55001:2024.

What to include in a air compressor service log book

This air compressor service log book covers 10 key areas:

• Compressor ID or asset number, make, model and type (screw or reciprocating)
• Rated pressure, air receiver capacity and location
• Date of each service entry and running hours at service
• Service type: routine, minor, major, repair or receiver inspection
• Compressor oil, oil filter, air filter and separator element changes
• Belts, drive coupling and cooler condition
• Air receiver condition, internal or external inspection and drain
• Pressure safety or relief valve test and set pressure
• Pressure switch, unloader and controls operation
• Technician name, parts used and next service due (date or hours)

How often should you complete this form?

Follow the manufacturer schedule for the compressor: oil, filters and separator elements at set running hours, belts and coolers checked regularly, and a major service less often. Duty cycle, ambient dust and heat all shorten the effective interval, so a hard working unit in a dusty workshop needs more frequent attention than the hour meter alone suggests.

The air receiver is a pressure vessel and has its own inspection cadence under AS/NZS 3788:2024, set by its hazard level (AS 4343-2014) and a competent person: typically periodic external inspections plus less frequent internal inspection and, where required, hydrostatic testing. Drain condensate from the receiver frequently, daily on a humid site, and log the receiver and safety valve checks alongside the compressor services so the pressure equipment record stays current.

Applicable regulatory standards

This template aligns with the following regulations and standards:

• Model Work Health and Safety (WHS) Act and Regulations, as enacted in each state and territory (in Victoria, the Occupational Health and Safety Act 2004 (Vic) and OHS Regulations 2017 (Vic))
• Model WHS Regulations, regulation 213 (maintenance of plant) and Chapter 5 pressure equipment duties
• AS/NZS 3788:2024 Pressure equipment - In-service inspection (air receiver)
• AS 4343-2014 Pressure equipment - Hazard levels (drives registration and inspection frequency)
• AS/NZS 3760:2022 In-service safety inspection and testing of electrical equipment (electrical parts)
• ISO 55001:2024 Asset management - Asset management systems - Requirements (controlled maintenance records and asset history)
