A fan powered terminal unit fptu commonly referred to as a fan powered box fpb is an air terminal unit which contains both a primary air inlet as well as a local motor and blower assembly.
This design allows the primary airflow to supply the cooling demand similar to single duct terminal units leaving the recirculating air section to provide the heating air volume.
Quiet type with dissipative silencers and hospital grade boxes are also available.
To be the most effective a box fan needs plenty of air behind them you can set it up on a.
Camair bx100 high performance box fan light gray.
The fan supplies a constant volume of air to the space consisting of primary air from the cooling system mixed with ceiling plenum re turn air.
This type of terminal unit provides a constant volume of air to the space but varies the ratio of plenum air to primary air to maintain the desired temperature.
Because the fan only handles the heating airflow which is typically less than the cooling airflow the fan can be smaller than the fan in series fptus.
The primary doas air is then sized for both the cooling load and the minimum ventilation air so the vav part of the box modulates the cool primary supply air to meet the load while the fan powered recirc air provides reheat capability.
Traditionally a permanent split capacitor psc type motor was employed in these air terminal units and was capable of local adjustment only.
The series box shown in figure 1 along with a parallel fan powered and a cooling only shut off box includes a supply fan in series with the vav damper.
The primary air and recirculated air sections operate independently of one another while both sections are controlled by the same input signal.
