How much air moves
Add the consumption of tools that operate together, then allow for hose losses, duty cycle and a reasonable margin.
Practical hire guide
Choose air with confidence.
You do not need to speak in CFM and bar to hire well. Start with the job, then use this guide to understand the package around it.
Start with demand
Six questions size the job.
The best compressor is not automatically the biggest. Correct sizing protects tool performance, fuel use, noise levels and hire cost.
- 01
What will the air power?
List every tool or process, including anything likely to run at the same time.
- 02
How much flow is needed?
Airflow is measured in CFM. Combined demand—and a sensible working margin—determines compressor size.
- 03
What pressure is required?
Pressure is measured in bar. The compressor must maintain the required pressure at the point of use.
- 04
How clean and dry must it be?
Some processes tolerate standard site air; others need cooling, moisture removal or fine filtration.
- 05
Where will it operate?
Indoor, urban, restricted-access and emissions-sensitive sites can change the ideal power source and layout.
- 06
What if the air stops?
Critical production or shutdown work may need standby capacity, remote monitoring or a rapid swap plan.
Air basics
Flow. Pressure.
Quality.
Three different requirements, one joined-up package.
How hard the air pushes
Higher pressure is not a substitute for enough flow. The required pressure must reach the tool after distribution losses.
How clean the air must be
Moisture, particles and oil matter more for coating, instrumentation and production processes than for many site tools.
Indicative demand
Common applications.
These broad ranges help start the conversation; tool manufacturer data, simultaneous use and hose layout should always inform final sizing.

Complete the package
The equipment between compressor and tool matters.
We can supply and size the full air path so pressure, quality and safety hold together from outlet to point of use.
Ask us to build the package →Air hose
Connects the compressor to the work area. Bore and length affect pressure at the tool.
Manifold
Splits one supply safely between several tools or work zones.
Air receiver
Buffers demand, smooths pressure and supports short bursts of higher airflow.
Aftercooler
Lowers discharge-air temperature and helps remove condensed moisture.
Dryer & filtration
Controls moisture, oil carryover and particles for more sensitive applications.
Fuel management
Scheduled refuelling and telemetry options help keep longer hires running.
Before delivery
A site-ready checklist.
01Safe, level position with suitable ventilation
02Clear vehicle access and unloading route
03Confirmed connection sizes and hose route
04Space to separate exhaust from work areas
05Noise or working-hour restrictions identified
06Authorised site contact available on arrival
07Fuel arrangements agreed for longer hires
08Any critical standby requirement discussed
