  • Comparison of airflow and contaminant distributions in

    Figure 1(b), linear diffusers in Figure 1(c), and perforated-floor-panel diffusers in Figure 1(d). Among these diffusers, the swirl diffusers and perforated-floor-panel diffusers generate low-height throws, which means that the air velocity from the diffusers decays quickly and becomes less than 0.3 m/s (60 fpm) at 1.35 m (4.5 ft) above the floor.
