What is ISO 8573-1 Oil-Free Certification
The ISO 8573-1 standard sets stringent criteria for compressed air purity, categorizing oil content into five levels, with Class 0 representing the highest level of oil-free quality. To achieve this prestigious certification, DREAM's compressors underwent rigorous testing to ensure that their output contained minimal to no oil particles, meeting the most demanding requirements of industries such as food processing, pharmaceutical manufacturing, and semiconductor production.
The meticulous testing process covered all forms of oil contamination - aerosol, liquid, and vapor - ensuring that every molecule of compressed air leaving DREAM's machines was of the highest purity. DREAM's unwavering focus on innovation and quality has resulted in its air compressors surpassing even the stringent standards set by ISO 8573-1 Class 0.
