Compressed Air Testing

Why It's Important:

Compressed air use in your manufacturing process must be controlled and monitored to provide a level of quality that meets your requirements. If compressed air comes into contact either directly or indirectly with your product, it must be considered as a potential hazard.

 

We can help you implement a robust monitoring plan to ensure that your compressed air system is in a state of control throughout the year.

What We Test:

  • PARTICLES - Rust, dirt, and metal shavings are just a few examples of possible particle contamination.

  • WATER - Length and condition of distribution piping, drops, dead-ends, condensate drain traps, and the 
    use of polymer tubing can contribute to excess moisture.

  • OIL - Even oil-free compressors can be contaminated with oil vapor (gaseous hydrocarbons) from intake air.

  • MICROORGANISMS - An improperly maintained compressor can provide conditions (water + oil + warm temperature) needed for microbial growth.

Audit Guide

Understanding your auditor’s terminology is essential to interpreting their requirements and passing your next audit. But even more importantly, knowing the proper terms and how to use them prevents miscommunication that can cost you time and money.

ISO 8573

ISO 8573 is an internationally recognized
standard that defines major contaminants in
compressed air and presents a
comprehensive system for air purity
designations. Testing according to this
standard will help ensure that your are able
to meet audit requirements.

  • Includes limits and sampling techniques for 
    Particles, Water, and Oil

  • Same standard used by filter manufacturers

  • Purity limits appropriate for many different uses

  • Purity classes 0-9, [P:W:O]

Regulating Associations

The food industry is currently in a state of
flux with regard to regulations. There are
many different regulating organizations,
and you may subscribe to one or many of
their requirements. Stay up-to-date.

  • SQF Safe Quality Food Institute

  • FDA Food & Drug Administration

  • BRC British Retail Consortium

  • FSSC Food Safety System Certification

  • GFSI Global Food Safety Initiative

  • IFS International Featured Standards on Food

  • FESP Canadian Food Safety Enhancement Program

Audit

Many manufacturers only begin testing their compressed air because of audit requirements or even
audit deficiencies. Knowing quality requirements and how to apply preventative measures is crucial to
creating a safe product, decreasing recalls, and taking proactive steps to passing your next audit.

Audit Lingo as it applies to Compressed Air:

  • HACCP - a preventative management system that identifies and analyzes hazards to food safety

  • Analysis Hazards – Compressed Air Contaminants: Particles, Water, Oil, and Microorganisms

  • Critical Control Points – Wherever compressed air comes into contact with the product or could become 
    contaminated: Point of Use, Valves, In-line filters, etc.

  • CCP Preventative Measures – Filter and Purification Equipment

  • Monitoring of CCP Preventative Measures – Regular testing of compressed air (quarterly, annually, etc.)

  • HACCP and CCP Log – Controlled document detailing the regular testing of compressed air and maintenance of filtration systems
