Typical Air Velocities in Ducts and Pipes

Typical air velocities in applications like ventilation systems or compressed air systems

Air velocities in ducts and pipes should not exceed certain limits to avoid high pressure loss and unacceptable noise generation. The values below can be used as guidelines for some typical applications.  

Air DuctsAir Velocity
(m/s)(ft/min)
Combustion air duct 12 - 20 2400 - 4000
Air inlet to boiler room 1 - 3 200 - 600
Warm air for house heating 0.8 - 1.0 150 - 200
Vacuum cleaning pipe 8 - 15 1500 - 3000
Compressed air pipe 20 - 30 4000 - 6000
Ventilation ducts in hospitals 5 - 8 1000 - 1500
Ventilation ducts in office buildings 7 - 11 1200 - 2000
