FSD 20 Specification Sheet

Fantech FSD Series 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. FSD Series fans offer substantially quieter
performance and are easier to install than axial arrangements. Fans could be mounted at any angle in any
point along the duct work and straight-through air flow design allows easy installation. Fans can easily be
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 FSD
Series fans are backed by Fantech’s Three Year Warranty.
