FAQs

Your fan powered terminal unit questions, answered.

Series fan-powered terminal units are used commonly in VAV zones that require heat during occupied hours and design higher supply airflows during all conditions.

The terminal unit fan is in series with the central fan. Primary air from the central fan always passes through the terminal unit fan.

The local series fan within the terminal unit operates whenever the unit is in the occupied mode. The fan can deliver either a constant or variable volume of air to the zone.

As the zone requires less cooling, the primary air damper closes. As the primary air damper closes, the air mixture supplied to the zone contains less cool air and more warm plenum air. Remote heat or terminal reheat can provide additional local heating.

Series fan-powered terminal units are also useful in low supply air temperature systems, since the terminal unit fan can be sized so that warm plenum air is always mixed with low temperature supply air. This raises the supply air temperature to an acceptable distribution level and reduces condensation potential.
