The most common VAV box is a single-duct terminal unit, which regulates the volume of air that each space requires by adjusting a damper with an automated controller and actuator. VAV terminals often include additional components such as hydronic or [electric heating coils](https://blog.priceindustries.com/what-are-electric-coils) and fans equipped with [variable-speed motors](https://blog.priceindustries.com/what-are-ec-motors).

The problem with pressure drop for terminal units is that there are a number of metrics that are often confused with one another despite referring to different performance variables. These include static pressure drop, velocity pressure drop, pressure drop associated with acoustics and pressure drop associated with accessories.
