FKD Series
Inline Centrifugal Fans
Description
A mixed flow centrifugal type exhaust/supply fan for moderate size ventilation applications specifically designed to bridge the transition from centrifugal
to axial. FKD Series fans offer substantially quieter performance and are easier to install than axial arrangements. Fans can be mounted at any angle in
any point along the duct work and straight-through air flow design allows easy installation. Fans can be easily removed from duct work for service. Fan
motors are capable of operating in air stream temperatures of 140
o
F. Motor bearings are a permanently sealed, self lubricating ball type. All fans are
100% speed controllable through a decrease in the voltage by using a solid state or transformer type control. All FKD Series fans are backed by
Fantech’s Three Year Warranty.
