The area of the primary supply diffuser array shall extend a minimum of 12 inches beyond the footprint of the surgical table on each side. No more than 30 percent of the primary supply diffuser array area shall be use for nondiffuser uses such as lights or gas columns. Because the greatest amount of the bacteria found in the OR comes from the surgical team and their activities during surgery, turbulent air patterns within an operating room are to be avoided.

To provide a unidirectional air pattern, laminar flow diffuser arrays Group E , sized to introduce air into the room at low velocities of maximum face velocities of 20 to 35 fpm, are used. The velocity is low enough to prevent secondary entrainment of room air into the supply pattern. Two filter banks for air handling serving ORs are required.
