    The Fantech FSD 20 Square Inline Duct Fan is a 3,225 CFM centrifugal supply and exhaust fan designed to provide high airflow with backward curved impellers. It is constructed for 20 inch square venting. FSD Series Duct Fans can install directly within equally sized square ductwork without the need for transitions. This unit is wired for 115 volts.
  • Backward Curved Impeller
  • Backward curved impeller blades allow particles to easily pass through the fan blades, preventing a build-up.
  • 100% Speed Controllable
  • On-demand ventilation and precision balancing of systems is controllable through voltage reduction.
  • External Rotor Motor
  • An external rotor motor allows the fan to operate in high-moisture or dust-laden areas.
  • Thermal Overload Protection
  • Thermal overload protection automatically resets the fan when temperatures get too high, avoiding potential damage to the unit due to overheating.
