Description
The Single Duct Supply Terminal consists of the
following components (see Figures 2 through 6).
· Galvanized steel round inlet duct, damper blade
in sizes from 4” (10.2 cm) to 16” (40.6 cm)
diameter; size 18 unit has a rectangular 16 × 24
inlet and two 16” (40.6 cm) diameter dampers.
· Four quadrant airflow measurement sensor.
· Rectangular, lined and insulated casing with slip
and drive outlet connections.
· Factory-mounted controls options.
· Electronic damper control – high speed or
standard speed
