Pressure Vessel Inspections for Air Receivers in NSW

Your air receiver stores compressed air under pressure, and by law it has to be inspected regularly while it is in service. Adaptive Air Compressors carries out onsite inspections across NSW to AS/NZS 3788, the Australian Standard for in-service inspection of pressure equipment.

How often does an air receiver need inspecting?
Every two years, alternating between an external and an internal inspection:
- External inspection – the outside of the vessel, its fittings and safety devices, checked while the receiver stays in place.
- Internal inspection – the vessel is isolated and opened so the inside can be checked for corrosion and damage.
So if this year’s inspection is external, the next one in two years is internal, and so on.
What we check
- The vessel shell, welds and supports, for corrosion, dents and damage
- The safety relief valve and pressure gauge
- Drains, fittings and connected pipework
- The compliance plate and vessel details
What you receive
A written inspection report for each vessel, recording its condition, anything that needs attention and when the next inspection is due. Keep it with your plant records; it is what an auditor or SafeWork inspector will ask to see.
If the inspection finds a fault, we can usually repair or replace the part on the same visit.
Who does the inspection
Our inspections are carried out by experienced compressed air technicians who meet the competency requirements of the standard. They work on air receivers every day, so they know what a healthy vessel looks like and what fails first.
Registering your vessel
Some pressure vessels must also be registered as plant in NSW. Registration is done by the owner, not by us, through Service NSW: Apply to register an item of plant.
Our inspection report gives you the vessel details you will need for the application.
Save a trip: inspect at your next service
We can inspect your receiver during a scheduled compressor service, so you only have one visit and one lot of downtime. Ask about it when you book.
Book a pressure vessel inspection
A pressure vessel inspection is carried out on site and can be combined with your next compressor service, so the receiver is only out of use once. We inspect air receivers across NSW from our Wyong workshop, and through our Wollongong branch for the Illawarra and South Coast. To book a pressure vessel inspection, contact us or call (02) 4393 1865.



If you are not sure when your last pressure vessel inspection was, check the report or the tag on the receiver, or send us the vessel details and we will help you work out what is due. Keeping each pressure vessel inspection on a schedule with your servicing means it is not missed.
