Centrifugal Fan
SF146C Series
DC EC
Applications
For precision cooling of telecom cabinets and industrial control panels, the SF146C-D092B0-03 (DC, 310 V DC, 1200 m³/h, 180 W) delivers high-volume, energy-efficient airflow where only a high-voltage DC bus is available. In North American commercial HVAC air-handling units and fan coil units, the SF146C-E092B1-02 (EC, 115 V AC, 1150 m³/h, 165 W) provides electronically commutated, speed-controllable ventilation on standard 115 V AC mains. For European and other 230 V AC single-phase installations such as data center CRAC units, cleanroom air circulation, and rooftop packaged systems, the SF146C-E092B3-01 (EC, 230 V AC, 1250 m³/h, 220 W) is suitable for higher-static, higher-airflow duty with integrated EC motor control.
