WebCommonly accepted duct velocities are indicated in the table below. Ducts are commonly classified as Low Velocity Systems - with air velocities up to 2000 fpm (10 m/s) Medium Velocity Systems - with air velocities in the range 2000 to 2500 fpm (10 - 13 m/s) High Velocity Systems - with air velocities greater than 2500 fpm (> 13 m/s) Web1) Maintain a 20 to 60 feet per minute velocity at the front edge. The edge velocity is in part related to the speed of exhaust gases entering the filters but diminished by the …
