FKD Series FKD Series
The best of both worlds
The high airflow with the pressure build-up of a circular fan
Fantech FKD direct drive, mixed flow centrifugal fans blend the high flow of axial fans with the higher
pressure, non-overloading characteristics of backward curved impellers. An excellent choice for exhaust or
supply applications where quieter performance and easy installation are important. Perfect for commercial
and institutional structures such as offices, hospitals, beauty salons, veterinary clinics as well as
residential applications such as kitchen range hood exhaust.
Mixflow impeller
FKD is a mixed flow fan, i.e. the fan impeller is a combination between a radial
and an axial impeller. It gives considerably higher efficiency, more airflow than
radial fans and is the best fan impeller type for 12”-20” ducting. Suitable to
use for both supply and extract air systems with large air volumes and medium
pressures.
Easy installation
Brackets are supplied with the fans to make installation or removal easier and
prevent the transfer of vibration to the duct.

Circular Inline Fan
External Rotor Motor
All FKD 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 protection and sealed ball bearings that protects motors from
overheating.
Maintenance Free Operation
All motors and impellers are designed as one integral unit, allowing for
excellent motor heat dissipation, even at a low RPM. Motors are capable
of operating in airstream temperatures up to 140° F. Motor bearings are
permanently sealed, self lubricating ball type.
• Permanently lubricated sealed ball bearings
• Excellent heat dissipation to ensure long motor life
• Terminal box with prewired electrical strip
• AMCA Air and Sound Listed
• 3 year warranty
