SF146D Series

Applications

For telecom cabinet and outdoor enclosure cooling where only a 48 V DC power bus is available, the SF146D-D092A8-01 (48 V DC, 1020 m³/h, 165 W) delivers high-volume centrifugal airflow without requiring an AC supply. In residential and light commercial HVAC equipment running on North American mains, the SF146D-E092A1-01 (115 V AC, 860 m³/h, 120 W) is suitable for standard ducted air handling, while the SF146D-E092A1-02 (115 V AC, 1050 m³/h, 165 W) provides the extra static pressure needed for longer duct runs or denser filter banks. For European and other 230 V AC installations, the SF146D-E092A3-01 (230 V AC, 860 m³/h, 120 W) serves as the energy-efficient baseline blower, and the SF146D-E092A3-02 (230 V AC, 1020 m³/h, 165 W) covers higher-demand air handling units and heat recovery ventilators. Where maximum airflow is critical, such as in data center CRAC units or industrial process cooling, the SF146D-E092B3-03 (230 V AC, 1160 m³/h, 220 W) provides the highest capacity in the series. All EC models offer precise speed control and low power consumption for variable-air-volume and smart building applications.
