Compressed Air Quality Testing for Compliance, Safety and System Performance
Professional compressed air quality testing helps verify that your air supply is suitable for its intended use. Tanair Compressors supports businesses with air quality testing for breathing air, process air and critical applications where contamination, moisture, oil or particulates can create risk.
Why Compressed Air Quality Testing Matters
Compressed air systems can be contaminated at multiple stages, from intake filtration through to point-of-use delivery. Regular testing helps businesses reduce risk, protect equipment, support workforce safety and maintain confidence in air quality for breathing air and process-critical applications.
The current live page also positions this service around COSHH, BS EN 12021 and air quality verification for UK businesses, so this rewrite keeps that same service focus while presenting it more clearly.
What We Test For
Compressed air quality testing helps assess the presence of key contaminants that can affect compliance, product quality, worker safety and system performance.
- Oxygen levels
- Carbon monoxide
- Carbon dioxide
- Oil aerosols, droplets or mist
- Water and moisture content
- Additional contaminants where required by your application or risk assessment
Who Air Quality Testing Helps
Testing is especially important where compressed air comes into contact with people, products or sensitive processes. This can include breathing air systems, food production, engineering operations, manufacturing and other environments where air contamination could create risk.
If your compressed air system needs to meet internal quality requirements, customer expectations or recognised standards, regular testing provides valuable assurance.
Breathing Air Contaminant Limits
Your current live page includes BS EN 12021 contaminant limits for breathing air. Below, that information has been converted into a cleaner HTML table so it is easier to read, compare and maintain.
| Substance | Limit / Requirement | Notes |
|---|---|---|
| Oxygen | 21% +/- 1% | Helps confirm suitable oxygen balance within the breathing air supply. |
| Carbon Monoxide | As low as possible, not more than 15 ml/m3 | Critical for breathing air safety due to toxicity risk. |
| Carbon Dioxide | Not more than 500 ml/m3 | Excessive levels can indicate air quality issues within the system. |
| Oil (droplets or mist) | Not more than 0.5 mg/m3 | Oil contamination can affect both safety and downstream equipment. |
| Contaminants | Kept as low as possible | Additional contaminants can be tested where required by your COSHH risk assessment or site requirements. |
| Water | Pressure dew point low enough to prevent condensation and freezing | Where usage and storage conditions are unknown, the live page states the pressure dew point should not exceed -11°C. |
Important: These limits are based on the BS EN 12021 contaminant section currently shown on your live Air Quality Testing page.
Review
We assess the application, air usage and any relevant quality or compliance requirements for your site.
Test
Samples and readings are taken to assess the condition and quality of your compressed air supply.
Report
You receive clear results with practical guidance on any actions, upgrades or maintenance that may be required.
Common Risks of Poor Air Quality
When compressed air quality is not properly controlled, problems can affect far more than just the compressor itself.
- Product contamination in quality-sensitive environments
- Increased moisture-related corrosion or system damage
- Oil carryover affecting downstream equipment
- Reduced confidence in breathing air safety
- Unexpected downtime linked to hidden air quality problems
- Difficulty demonstrating compliance or quality control

Frequently Asked Questions
A few of the most common questions businesses ask about compressed air quality testing.
What is compressed air quality testing?
It is the process of checking compressed air for contaminants such as oil, moisture, gases and particulates to help verify whether the air is suitable for its intended use.
Who needs air quality testing?
Any business using compressed air in breathing applications, regulated environments or quality-sensitive production processes can benefit from routine testing.
Can you test for specific contaminants?
Yes. If your site risk assessment or application requires checks for particular contaminants, testing can be tailored accordingly.
How often should compressed air be tested?
Testing frequency depends on application and risk. Breathing air and higher-risk uses are usually tested more frequently than general process air systems.
