HEPA/ULPA filtration and strict protocols keep cleanrooms compliant.
Pharmaceutical cleanrooms prevent contaminants from entering manufacturing areas, protecting product safety and compliance.
Maintain HVAC and filtration systems on schedule to keep cleanroom classifications within spec.
“Maintain HVAC and filtration systems on schedule to keep cleanroom classifications within spec.”
Willis Whitfield pioneered the modern cleanroom concept in 1962.
What is a cleanroom classification?
It describes the allowable number and size of airborne particles per cubic meter, often defined by ISO 14644.
How are cleanrooms kept clean?
Continuous filtration, controlled airflow, and strict protocols minimize contamination.
Do cleanrooms require special HVAC systems?
Yes. Cleanrooms use high‑efficiency filtration and precise airflow control to maintain standards.
