Uni-directional Theatre Flow Units
The way in which laminar flow theatres work is, very basically, to filter the air and create a powerful, calm and uniform unidirectional airflow.
They rely on fans to create air velocity, which may be downward. There can be multiple laminar flow diffusers in a single operating theatre.
Any turbulence can negate the bacterial reduction and removal effect of the system, so it is very important that operating theatre personnel move around carefully and deliberately.

A unidirectional flow theatre is an absolute necessity when it comes to preventing surgical sight infections in operational theatres.
High efficiency particulate air (HEPA) filters play a key role in almost completely reducing the number of airborne bacteria which are the cause of most hospital acquired diseases.
