North‑American food & pharma sectors raise procurement thresholds for Class 0 oil‑free compressors

Updated technical specifications for North‑American food and pharmaceutical projects list ISO8573‑1 Class 0 oil‑free compressed air as a mandatory tender requirement. End‑users phase out oil‑injected screw compressors and increase purchases of VSD oil‑free models. Buyers require third‑party air‑purity test reports alongside standard certifications. Chinese exporters shall prepare complete documentation to avoid customs and project‑acceptance risks.
