Speed Controls - Greenheck VFCB Installation, Operation And Maintenance Manual

Speed Controls

Speed controls may be used on Model VFCD fans
for manual adjustment of the fan's performance (for
final system balancing) or to control the fan's output
in confined spaces, such as conference or meeting
rooms. The fan can be adjusted to 60% of design
airflow with a speed control. This reduction in airflow
and fan speed is also accompanied by a reduction in
noise level. Solid state speed controls are available for
a range of applications up to 15 amps. Speed controls
can be used to operate more than one fan if the
combined total amperage of the fans does not exceed
the control rating.
