Control Accessories
Speed Controls
Speed controls may be used
on model SP and CSP 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 do not exceed the control rating.
For use with shaded pole and permanent split capacitor (PSC)
motors. Available shipped loose or mounted internal or external.
Switches
Switches may be used on model
SP and CSP fans to enable manual
control of your fan or fan and light
combination. There are several
options to fit your application.
