Talk to an expert The basics of buying a compressor

Your gateway to the world of compressed air - find what you need:

Atlas Copco Compressors is a leading manufacturer of energy efficient industrial air compressors, blowers, nitrogen and oxygen generators

Did you know the kW power rating of a compressor’s motor does not provide enough information to specify a new compressor?

There could be a number of pressure/flow variants within each air compressor kW category. E.g. Atlas Copco has four models in the 11 kW range that represent a 30% differential in flow rate (from 28.7 l/s to 35.8 l/s at 7 bar.g) and over 32% difference in the unit’s purchase price! So the question becomes how do you choose or size a compressor? Which air compressor is right for your business? Which air compressor supplier should I choose?

Modern compressed air equipment, when correctly matched in terms of compressor pressure and flow to process demands, can offer reduced specific energy requirements, improved productivity, and lower lifecycle costs. Their enhanced performance may allow a lower kW rated machine to be specified at a correspondingly smaller purchase price and reduced running costs in comparison to higher rated equipment. It pays to apply a few essential rules when choosing a new compressor:

Conduct an air audit

Assess present and future needs by first checking out the existing system, from air output to point of use, with a thorough air audit.

Match the air demand

Do not rely solely on the stated motor power rating to match the compressor performance to the process air demand.

Pressure + flow = energy = cost

Start with the pressure and flow requirement and then find the best fit in terms of drive motor power. Always keep in mind: pressure + flow = energy = cost

Always prioritise the flow and pressure
when you are choosing an air compressor!

Understanding compressed air quality and compressed air treatment


A small change can make a big difference in your pocket!

Air leaks, overdue servicing, inefficient running are all problems that face compressed air users everywhere. And though you may feel your installation is in good condition, you'd be surprised to find out what a trained eye can spot. Watch this video to find out why you should have an #airCHECK.
