The Fantech FSD 26 Square Inline Duct Fan is a 6,993 CFM centrifugal supply and exhaust fan designed to provide high airflow with backward curved impellers. It is constructed for 26 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 208/460 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.
