ExTERNAL ROTOR MOTORS
All FSD Series fans utilize our unique external rotor motors.
The motor’s enclosed design allows the fan to operate in high
moisture, lint and dust laden air. The motors are a permanent
split capacitor type, with automatic reset thermal overload
protection and sealed ball bearings.
These features ensure long life
and maintenance free operation.
All motors and impellers are
designed as one integral unit,
allowing for excellent motor heat
dissipation, even at a low RPM.
