Inline Mixed Flow Duct Fans
With Fantech's FKD Series fans, "going with the
flow" has never been easier. These fans are specifically designed to bridge the
transition between centrifugal and axial by combining the high flow of axial
designs with the higher pressure, non-overloading characteristics of backward
curved impellers. Fantech's "The Straight Way" inline designs minimize system
losses while being extremely compact. The round inline design keeps air
moving in ductwork sized from 8" to 20". 100% speed controllability gives
extreme flexibility where there is need for varying airflow.
The lightweight, compact design FKD Series fans mount at any angle, at any point
along the ductwork.
FKD’s performance features:
- Galvanized steel housing features baked
powder coat finish
- External rotor motor with built-in thermal
overload protection and automatic reset
- Tested and approved by UL and CSA (or equals)
- Suitable for airstream temperatures up to
140° F
- Permanently lubricated sealed ball bearings
- 100% speed controllable for highly efficient
and economical airflow
- Airflow up to 6291 CFM
- Terminal box with prewired electrical strip
- Mixed flow impeller
- Excellent heat dissipation to ensure long
motor life
- Three-year warranty
A balancing act that’s easy to perform
With FKD Series fans, 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, transformers or VFD's.
Direct drive eliminates the need for continuous belt alignment, tension
adjustment and ongoing maintenance.

Performance shown is for
installation type D - Ducted inlet, Ducted outlet. Speed (RPM) shown is nominal.
Performance is based on actual speed of test. Performance ratings do not include
the effects of appurtenances in the airstream.
* The sound ratings shown are loudness values in fan sones at 5ft. (1.5m) in
hemispherical free field calculated per AMCA Standard 301. Values shown are for
installation Type D: ducted inlet fan sone levels. Ratings do not include the
effect of duct end correction. All sone values shown are calculated at 0.5"
(static pressure in inches W.G.).
Note: Three phase motors are
wound for 230/460 volt. Motors are prewired for 460 volts but may be delivered
as 230 volt or may be rewired in the field.
1 Recommended speed
control rating 5A.
2 Recommended speed control rating 10A.
3 Recommended speed
control rating 15A.
