FSD Series
Inline Mixed Flow Square Fans
Fantech, Inc. certify that the
Ventilators shown herein are
licensed to bear the AMCA
Seal. The ratings shown are
based on tests and procedures
performed in accordance with
AMCA Publication 211 and
AMCA Publication 311 and
comply with the requirements
of the AMCACertified Ratings
Program.
The FSD Series is a 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. 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.

Performance certified is for installation type A - Free inlet, free outlet. Speed (RPM) shown is nominal. Performance is based on actual speed of test. Performance ratings do not include the effects of
appurtenances (accessories). 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.
† 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 A: free inlet hemispherical fan
sone levels. All sone values are calculated at 0.5” (static pressure in inches W.G.).
‡ Sone Value at 0.75” (static pressure in inches W.G.).
