Compressed air can contact food directly or indirectly through packaging, conveying, cleaning and instrumentation. In these applications, oil contamination is a quality and compliance risk.
Define the air-quality class
ISO 8573-1 defines purity classes for particles, water and oil. The correct class comes from the process risk assessment and applicable food-safety standard.
Compression technology matters
An oil-free compressor removes oil from the compression chamber. The rest of the system still needs appropriate filtration, drying and monitoring to reach the required point-of-use quality.
Document the system
Keep equipment certificates, maintenance records, air-quality test results and change-control documents available for audits.
Our team can help configure an oil-free package for food, beverage and packaging applications.
