Rectangular Damper Selection Procedure
Locate the required CFM on the Rectangular Damper
Selection Data table below. This table is based on an
airflow velocity of 1000 FPM across the damper. This
is the recommended velocity for quiet operation and
normal pressure drop through the damper. When space
considerations or design criteria
dictate, dampers may
be selected for other face velocities by using the
multipliers listed in the notes associated with the table.
Move across the table and find the damper selection,
which will provide the required CFM and fit within
the ceiling area where the damper will be located.
Pressure drop across the damper is shown in parenthesis
below the CFM
