TOUL Mobile laminar flow eliminates 99.995% of bacteria and viruses and prevents contamination of surgical instruments and the operating field throughout the surgery and without time limits. The TOUL mobile laminar flow is direct and eliminates obstacles such as the surgeons' head or the C-arm. Between the ultra-clean air outlet and the critical areas to be protected, there is always an obstacle in the way, in the case of cardiology the C-arch, in the case of the other specialties, the operating lamps and the surgeons' head. TOUL produces a horizontal laminar air flow that is directed on the instrument table and on the operating field, without any interposition of obstacles, maximizing the effectiveness of prevention. The reduction of bacterial load in the operating field and on the instrument table is essential to prevent any type of bacterial infection.
