We custom-designed this high-pressure radial induced draft fan for a scrubber application, with alloy 2205 airstream construction, custom purge air shaft seals, pie-split housing, and an integral inlet box. Configured as a center-hung Arrangement 7 fan, a flexible coupling is used to connect the fan shaft to the motor shaft, and the entire fan assembly is mounted on a unitary base. The application required a severe duty motor rated for use with a Variable Frequency Drive (VFD).
