Model VFCD/VFCB Vertical Fan Coil

®

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.
