TORQUE
COUPLING

The

torque
coupling
keeps
the
fan

speed
at
2
900

rpm
rated

or
below
to

conserve

horsepower
at

high

engine

speed
It
also

helps
reduce
fan
noise
to

a
minimum

during

opera

tion

This
unit
is
filled
with
a

special

silicone
oil
used

as
a
fluid

coupling

which
controls
the

fan

speed
Silicone

oil

can
not
