Single Inlet Centrifugal Housing Fans
BAS/BNS series are single inlet centrifugal fans. The core technologies—backward curved impeller with variable width—enable the fan operating in high-efficiency zone at 50/60Hz without VFD, delivering efficient, reliable airflow for equipment cooling, MAU (Make-up Air Units), exhaust systems, general ventilation applications with installation constraints.
