Air Velocity Control

Existing research suggests that high velocity air at the surgical table can increase the risk of surgical site infection. Air curtain systems offer better control of air velocity over the surgical table than laminar flow diffusers.

As the relatively lower velocity air exits the laminar diffusers above the patient, the higher velocity air from the linear slot diffusers will pull the laminar flow outwards. The laminar flow will expand to fill the zone enclosed by the air curtain, mitigating the tendency for the cold air mass to accelerate as described earlier.

The net result is the ability to maintain air velocities at the operating table close to, or even slower than, those at the diffuser face.
