Compressed Air Samplers – Airborne Contaminant Collection Systems

What is a Compressed Air Sampler?

A compressed air sampler is an instrument used to collect and analyze contaminants such as particles, microorganisms, and gases from pressurized air systems.

It ensures compressed air quality, contamination control, and regulatory compliance.

What Do Compressed Air Samplers Measure?

These systems measure:

• Microbial contamination

• Particulate matter

• Chemical contaminants (e.g., oil, VOCs)

Results help verify air purity in critical processes.

How Do Compressed Air Samplers Work? 

1. A portion of compressed air is diverted from the system

2. Air pressure and flow are regulated

3. Air passes through a collection medium (filter, agar, etc.)

4. Contaminants are captured

5. Samples are analyzed for microbial or particulate content

Controlled sampling ensures accurate representation of air quality.
