ISO 8573-1 Compressed Air Quality Standards

This technical article discusses ISO 8573-1, which defines the quality of compressed air in three categories: particles, water, and oil. Each category is assigned a rating, with lower class numbers indicating cleaner air. The article outlines the significance of maintaining compressed air quality, noting that contaminants can lead to equipment damage, product quality issues, and operational downtime. It emphasizes the importance of achieving compliance with ISO 8573-1 standards to safeguard production processes and reduce maintenance costs. The article details the types of dryers and filters suitable for maintaining air quality, including refrigerant, desiccant, and membrane dryers, as well as particulate and coalescing filters. It also highlights the necessity of strategic equipment placement and regular maintenance, such as tracking pressure drops and servicing filters. The article concludes by encouraging readers to assess their systems to ensure compliance with ISO 8573-1, thereby enhancing operational reliability and product quality.
