Laminar flow theatres aim to reduce the number of infective organisms in the theatre air by generating a continuous flow of bacteria free air. Then clean properly the working chamber from ceiling followed by side glass. Laminar air flow LAF ventilation systems in operating rooms were popularized by Sir John Charnley in the 1960s for use during joint replacement implantations after a series of trials showed a significant decrease in infections attributed to laminar flow use.
Vertical laminar flow with air curtain system is also more friendly to design as it provides only one third of its volume through the center panels which are usually uniformly spaced within the air curtain and over the operating table.
