In a hospital setting, air quality is literally a matter of life and death. However, a "one-size-fits-all" approach to air filtration does not work in healthcare. In this FAQ, DSX Purification details the highly specific Fan Filter Unit (FFU) engineering requirements across four critical medical zones: Operating Rooms (OR), Intensive Care Units (ICU), Airborne Infection Isolation Rooms (AIIR), and Hospital Pharmacies/Labs. Discover how custom airflow dynamics, negative pressure management, and Room-Side Replaceable (RSR) designs ensure strict infection control, patient safety, and medical compliance.
