Air Compressor Hire Perth
We hire towable diesel air compressors for Perth sites running jackhammers, breakers, rock drills, needle guns and air tools generally.
Compressors are sized on two numbers and people usually only quote one. Pressure in psi is the easy one. Volume in cfm is the one that decides whether your tool actually runs, and running two tools off one machine doubles what you need.
Delivered on site, fuelled and ready. Tell us the tools and how many run at once and we will get the size right first time.

cfm Decides Whether Your Tool Runs
Pressure, quoted in psi, is how hard the air pushes. Volume, quoted in cfm, is how much air the machine can keep delivering. Almost every tool on a Perth site wants a similar pressure, so pressure rarely decides anything.
Volume is what separates a compressor that runs your breaker all day from one that keeps the pressure gauge dropping and the tool stuttering. An undersized machine does not fail, it just works badly, which is why people put up with it for a whole hire.
| The Number | What It Describes | Why It Decides The Hire |
|---|---|---|
| cfm | The volume of air the compressor keeps supplying | Undersize it and the tool stutters and works slowly all day |
| psi | The pressure the air is delivered at | Most site tools want a similar pressure, so this rarely decides anything |
| Number of tools | How many run off the machine at the same time | Two tools want roughly double the cfm, not a slightly bigger machine |
| Hose length and diameter | How far the air travels and through what bore | A long thin hose loses pressure before the air reaches the tool |
| Duty | How much of the hour the tool is actually triggered | Continuous breaking is a very different load from occasional use |
Two Tools Is Not One Slightly Bigger Machine
Running two breakers off one compressor means adding their air demand together, and then some. Splitting an undersized machine across two tools is the fastest way to make both of them useless. Tell us the real number of tools at the booking.

Call Us NowWhat Perth Sites Run Off A Compressor
- Jackhammers and concrete breakers on driveways, slabs and footings
- Rock drills, which Perth limestone gives plenty of work to
- Needle guns and scabblers for concrete preparation
- Air saws and cut-off tools where a power lead is not practical
- Blowing out drilled holes, formwork and trenches before a pour
- Tyre inflation and general shop air on a yard or a depot
Breaking Limestone Is Often A Machine Job
If the job is a large area of Perth limestone or hard rock, a hydraulic breaker on an excavator will usually beat two people with jackhammers, on both time and cost. Our rock breaking page covers that side of it. A compressor is the right answer for confined, awkward or finish work where the machine cannot get in.
Hoses, Moisture And Getting Air To The Tool
Air loses pressure travelling down a hose, and it loses more the longer and thinner the hose is. A machine that is correctly sized at the compressor can still be undersized at the tool if the run is long.
Compressed air also carries moisture, and a humid Perth summer day makes more of it than a dry winter one. Water in the line ends up in the tool, which is what shortens its life.
Worth Sorting Before The Hire
- How far the tool works from where the compressor can park
- Whether you have hose of the right bore, or need it supplied
- Somewhere firm and level for a towable unit, with clearance for exhaust and airflow
- How close the nearest boundary is, because these are not quiet machines
- Ear protection for anyone near the tool, which is louder again than the compressor

It depends on the specific tool and how many run at once, and the number that matters is cfm rather than psi. A single breaker and two breakers are very different machines. Tell us the tools you are running and how far they work from where the compressor parks.
psi is the pressure the air is delivered at, cfm is the volume of air the machine keeps supplying. Most site tools want a similar pressure, so cfm is what actually decides the hire. An undersized machine on cfm does not fail outright, it just makes the tool work badly all day.
Only if the machine is sized for both together, which means adding their air demand rather than assuming a slightly bigger unit will cover it. Splitting an undersized compressor across two breakers usually makes both of them close to useless.
Tell us what you need when you book. Hose bore and length change how much pressure actually reaches the tool, so it is worth sorting at the same time as the machine rather than turning up with whatever is in the shed.
For confined, awkward or finish work, yes, because the machine cannot get in. For a large area of Perth limestone or hard rock, a hydraulic breaker on an excavator will usually beat two people with jackhammers on both time and cost.
