SLD fabricates laminar airflow systems for ORs. AirFRAME® is born from downflow cleanrooms where air, lighting, and ceiling mounts form a single fixture. Modularity reduces schedule, coordination, and site conflicts, lowering costs. Indigo-Clean™ lighting reduces SSI rates by 73% and kills SARS-CoV-2. SLD products are 'Designed for Zero'™ (D4Z) infections.
