Compressed air is used throughout modern industry, from powering pneumatic equipment to coming into direct or indirect contact with products and production processes.
But while businesses often focus on compressor performance, pressure and energy efficiency, the quality of the compressed air itself can sometimes be overlooked.
Contaminants such as moisture, oil and particles can affect equipment reliability, product quality and the performance of your compressed air system.
At PCM Air Power, we provide compressed air solutions and support to businesses throughout Belfast, Northern Ireland and Scotland, helping customers maintain reliable and effective compressed air systems.
What’s Actually in Your Compressed Air?
Atmospheric air naturally contains moisture and airborne contaminants.
Once air enters a compressor and is compressed, contaminants can become concentrated within the system. Depending on the compressor, installation and application, compressed air can potentially contain:
- Water and water vapour
- Oil
- Dust and solid particles
- Other contaminants
That’s why producing compressed air isn’t always enough—the required air quality also needs to be considered.
1. Protect Product Quality
For businesses where compressed air comes into contact with products, packaging or sensitive manufacturing processes, air quality can be particularly important.
Contamination within the compressed air supply has the potential to compromise processes and affect finished-product quality.
Testing helps businesses understand the quality of the air being delivered rather than simply assuming the system is performing correctly.
2. Protect Pneumatic Equipment
Moisture and contaminants don’t only affect products—they can also damage equipment.
Poor-quality compressed air can contribute to corrosion, premature component wear and problems with pneumatic machinery.
Maintaining appropriate air quality helps protect downstream equipment and can contribute to improved reliability and longer component life.
3. Identify Problems Within Your System
Compressed air quality testing can provide valuable insight into how effectively the wider system is performing.
Unexpected levels of moisture, oil or particles may indicate that filtration, drying or other parts of the air treatment system require attention.
Identifying these issues early allows corrective action to be taken before they develop into larger problems.
4. Verify Your Air Treatment
Installing filters and dryers is an important step, but how do you know they’re delivering the required results?
Testing provides evidence of compressed air quality and helps verify that air treatment equipment is performing as intended.
This is particularly valuable in applications where maintaining a specified standard of compressed air is essential.
5. Match Air Quality to Your Application
Not every application requires the same level of compressed air quality.
The appropriate solution depends on how and where the air is being used.
Understanding your requirements allows the correct combination of compressors, dryers, filtration and air treatment equipment to be selected without unnecessarily over-treating or under-treating the air supply.
A Complete Approach to Compressed Air
Air quality should be considered as part of the complete compressed air system.
Compressor selection, filtration, drying, pipework, maintenance and regular testing all contribute to delivering reliable compressed air at the point of use.
Taking a system-wide approach can help protect equipment, support production quality and identify potential problems before they result in costly disruption.
