Compressed Air Quality Testing – Why It Matters

Compressed Air Quality Testing – Why It Matters

At Rotonair, we understand that compressed air plays a crucial role in countless commercial and industrial processes. In many industries, the quality of that air isn’t just important—it’s essential.

Poor air quality can lead to product contamination, increased maintenance costs, and even production downtime. The main culprits behind poor air quality? Water, oil, and particles—the three primary contaminants found in compressed air systems.

Where Contaminants Come From

Contaminants can enter your compressed air system from several key sources:

• Ambient Air Intake: The air drawn into your compressor brings in environmental pollutants like water vapour, dust, and hydrocarbon fumes.

• The Compression Process: Mechanical operation introduces additional contaminants, including compressor oil (especially in oil-lubricated systems), wear particles, and vaporised fluids.

• The Air System Itself: Older piping and tanks can harbour rust, scale, mineral build-up, and microbial growth, all of which degrade air quality over time.

Without proper air treatment and testing, your compressed air system could be a hidden liability—especially in sensitive sectors like food & beverage, pharmaceuticals, or electronics, where air may come into direct or indirect contact with products or packaging.

Site Testing & Compliance

Our trained engineers can visit your site with calibrated ISO 8573 air quality testing equipment* to carry out on-site compressed air purity testing. We provide certified results you can measure against ISO 8573-1 standards, covering:

• Particle content

• Dew point

• Oil vapour concentration

This periodic point-of-use testing helps ensure your system remains compliant, efficient, and fit for purpose.

Meeting Industry Standards

Whether you’re working toward ISO 8573, ISO 12500, or ISO 7183 compliance, maintaining high air quality is not optional—it’s a critical part of your hazard analysis and critical control point (HACCP) planning.

At Rotonair, we offer expert advice on your existing compressed air setup and provide high-quality, tailored solutions to help you achieve and maintain the air standards your business demands.

Our Approach: From System Design to Point-of-Use Purification

Clean air begins before it enters your distribution system. Pre-treatment is vital to protect your air receivers, pipes, and end-use equipment. But that’s only the start.

We also focus on point-of-use purification, ensuring that the air quality at each critical application meets the required specification. This targeted approach avoids unnecessary over-treatment and offers a cost-effective path to compliance.

It All Starts With a Question: What Air Quality Do You Need?

At Rotonair, every consultation begins with this essential question. We analyse your requirements based on your industry, environment, and system design to offer tailored, reliable recommendations.

By combining deep expertise with industry-leading testing and standards compliance, we help you build and maintain a system that meets your purity goals today—and adapts to your demands tomorrow.
