||The capture efficiency of local exhaust systems is defined and the effect of exhaust systems on contamination reduction is discussed. The functional relation between capture efficiency and exhaust air flow may be described by S-shaped curves. The combined effect of capture efficiency and degree of use is considered; the level of combined effect depends mainly on the smaller of the 2 parameters. Local exhaust systems with a built-in filter and recirculated exhaust air are dealt with.
