Cut Carbon with Efficient VSD Screw Compressors

Practical advice for QA and plant managers in South Africa’s FMCG sector

In South Africa’s highly regulated FMCG environment, compressed air is treated as a direct ingredient in many food and beverage processes. Whether it is used for packaging, sorting, conveying, aeration, bottling, or cleaning, air quality directly affects product safety and regulatory compliance.

For QA teams, plant managers, and engineering leads, understanding ISO 8573 compliance, air purity levels, and contamination risks is essential. At Wright Air, we work with top FMCG manufacturers across South Africa to design, audit, and optimise food-grade compressed air systems that meet global safety standards.

Why Compressed Air Purity Matters in Food Manufacturing

Compressed air often contains:

Water vapour & liquid water
Oil aerosols & vapours
Solid particles (dust, rust, microorganisms)
Hydrocarbons and odours

These contaminants can lead to product spoilage, microbial contamination, packaging failures, safety breaches, HACCP non-compliance, and costly recalls.

ISO 8573: The Air Purity Standard

ISO 8573 defines allowable limits for Particles, Water, and Oil.

Food plants typically require:

Class 1–2 for particles
Class 1–2 for oil
Class 2–3 for moisture

Direct vs Indirect Contact Air

Direct Contact examples:
• Mixing, cutting, cooling, drying, blowing off product, filling & aeration
Requires ISO 8573 Class 1.

Indirect Contact examples:
• Conveying, sorting, pneumatic control, robotics, packaging equipment
Requires moderate to high purity depending on risk.

Top Contamination Risks
1. Water contamination – microbial growth.
2. Oil contamination – product taint and residue.
3. Particulates – dust, rust, microorganisms.
4. Poor filtration maintenance.
5. Incorrect piping design.

How FMCG Facilities Can Ensure Compliance
1. Implement an ISO 8573 purity roadmap.
2. Test compressed air regularly.
3. Use correct filtration and drying.
4. Select the right compressor (oil-free ideal).
5. Maintain compliance with monitoring tools.
