FC Fans With Inlet Guide Vanes
Trane’s forward-curved fans with inlet
guide vanes pre-rotate the air in the
direction of the fan wheel. This decreases
static pressure and horsepower. The
unloading characteristics of a Trane FC
fan with inlet guide vanes results in
superior part load performance.
Variable Frequency Drives (VFD)
Variable frequency drives are factory
installed, wired, and tested to provide
supply fan motor speed modulation.
VFD’s are quieter and more efficient than
inlet quide vanes and may even be
eligible for utility rebates. The VFD’s are
available with and without a manual
integrated bypass option, controlled
through the human interface (HI) panel.
Bypass control provides full nominal
airflow control to CV zone setpoints in the
unlikely event of a drive failure by
manually placing the drive in the bypass
mode.
Field Installed Accessories

without mixing box
• Programmable sensors with or without
night set back for CV and VAV systems
• ICS zone sensors used with Tracer ®
system for zone control
• Field installed module kits available for
field upgrade of controls
