Operio focused laminar air flow reduces the contamination in the operating room up to 95% and ensures that the instruments and the operating field maintain the sterility during surgery. The system is mobile and can immediately be used without any construction works. It is ideal to improve immediately aseptic conditions in existing operating rooms and especially suitable for implant surgeries. The focused laminar flow acts directly on the surgical site and instrument table without being impeded by surgical lights or medical staff, thus reducing by up to 95% the bacterial load on the surgical site and instrument table. The mobile laminar flow unit also complies with the rigorous standards of ISO class 5 for extreme sterile conditions in operating rooms.
