Oil-Free Air Compressors for Industry

Oil-free compression can be relevant where oil contamination could affect products, processes or equipment. The complete compressed air system, not only the compressor, determines the quality of air delivered at the point of use.

Applications

Food and beverage, pharmaceutical, electronics and other sensitive processes can require stringent compressed air specifications. The correct design depends on a documented risk assessment and application-specific quality targets.

Air Quality and ISO 8573-1

ISO 8573-1 provides a framework for expressing compressed air purity classes for particles, water and oil. Product specifications and independent test evidence must be checked before making any specific quality or certification claim.

Selection Checklist

• Required free air delivery and pressure
• Target particle, water and oil purity classes
• Energy consumption at realistic part-load demand
• Dryer and filter requirements
• Service accessibility, redundancy and operating risk
