The Carnes Model AC Constant Volume (Series Flow) fan terminals are designed for
commercial HVAC applications that require accurate temperature control and constant airflow to the conditioned space.
The internal fan runs continuous in the occupied mode. Controls modulate the damper to provide the proper amount of blending
between the primary air and the warm floor plenum air. Hot water or electric heating coils may be added to provide additional
heat if required. Constant Volume fan powered terminals typically serve the perimeter zones the may require heat while the
interior zones demand cooling. Significant operating savings are gained through the recovery of floor plenum heat and the
reduced central fan horsepower requirements.
