• 100% speed controllable
• Airflow up to 6993 CFM
• 18” to 26” square duct dimensions
• External rotor motor
• Automatic reset thermal overload protection
• Excellent heat dissipation, ensuring long motor life
• Terminal box with pre-wired electrical strip
• Mixed flow impeller design incorporates high flow
with higher pressure, non-overloading characteristics
and automatic reset thermal overload protection
• Suitable for airstream temperatures of up to 140° F
• UL Listed
• Three-year warranty
AUGUST 2009
Fantech FSD mixed flow centrifugal type exhaust/supply fans
for moderate size ventilation applications were specifically
designed to provide the high flow of axial designs plus the
higher pressure, non-overloading characteristics of backward
curved impellers. Fan motors are capable of operating in air
stream temperatures up to 140°F. Motor bearings are a
permanently sealed, self lubricating ball type.
The square design provides a larger discharge area than tubular
centrifugal or vane axial fans, so outlet velocitites are reduced
for quieter operation. 100% speed controllable through voltage
reduction allowing for on-demand ventilation or precision
balancing of systems.
Total control for optimum results:
System balancing is achieved by measuring the system flow
or pressure and adjusting the fan performance by “dialing in”
or setting the fan speed using inexpensive solid state speed
controls. Direct drive eliminates the need for continuous belt
alignment, tension adjustment and ongoing maintenance.

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.
