The Sterilflo System® is designed to adapt to the ceiling of the modern operating room. Unlike a straight laminar solution, which requires an unbroken array of diffusers, the Sterilflo System® utilizes specially designed laminar panels in conjunction with perimeter panels that produce an air curtain of a known profile. This permits discrete locations of the laminar panels, making it possible to place surgical lights, gas columns, intravenous tracks, and other items in logical locations between the perimeter and center panels. Thus, the Sterilflo System® adapts to the ceiling plan rather than adapting the ceiling plan to the system.
