Read our privacy policyThe FG Series is a centrifugal inline exhaust and supply fan designed for efficient ventilation in medium-sized applications. Its straight-through airflow design allows easy installation at any point in the duct system and in any mounting position. Using optional FC mounting clamps, the fan can be quickly removed for cleaning or maintenance. Built to fit standard spiral duct dimensions, it eliminates the need for transition pieces and simplifies setup. The fan’s motor operates reliably in airstreams up to 140°F, featuring permanently sealed, self-lubricating ball bearings for maintenance-free performance. Speed can be precisely adjusted with either solid-state or transformer-type controls.
