The Charnley-Howorth EXFLOW system has two important design parameters. One is the use of multiple extract points at ceiling height and the other is that the velocity across the supply face varies, being highest at the center and reducing outward to the periphery. This gradation of velocity is obtained by the use of an air diffuser plate, the center section having a greater number of holes and therefore a faster velocity. The operational experience with the EXFLOW systems installed in a hospital in Great Britain is described in detail.
