Guidelines For Air Velocities - Capital Coil Air

If you are purchasing an air handler unit, you probably will not have worry about the coil’s face velocity as most coils come pre-sized at the acceptable face velocities. Fan coils also come pre-sized with the correct CFM’s. However, if you are replacing an existing cooling coil, the face velocity must remain at or below 550 ft/minute!!

Air Velocity Measurement Dwyer Instruments

In air conditioning, heating and ventilating work, it is helpful to understand the techniques used to determine air velocity. In this field, air velocity (distance traveled per unit of time) is usually expressed in feet per minute (FPM).By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time.
