Technical Specifications

Working Principle
Conditioned air from the HVAC system enters the OT plenum and passes through an airflow equalization chamber. The air is then filtered through a high-efficiency HEPA filter, removing airborne particles, bacteria, and contaminants. The specially designed grille and equalizing screen ensure uniform laminar airflow across the surgical zone, creating a sterile environment and minimizing contamination risk during medical procedures.
