12V Centrifugal Blower Fan 9733, 46 CFM, 4-Wire PWM, Dual Ball Bearings

Model bfb1012eh 12V DC cooling fan designed for compact, high airflow cooling in electronic and industrial applications. Key benefits and reasons to choose this fan: - Reliable high airflow for effective heat removal, delivering 46 cfm to keep components running at stable temperatures. - Strong static pressure performance of 2.814 inches H2O to push air through tight passages, filters, or dense heat sinks. - Compact footprint of 97 x 94 x 33 mm to fit constrained spaces where larger fans will not. - Wide operating voltage range from 7.0 to 12.6 V for compatibility with varied 12V DC systems. - Four wire connection for secure electrical integration and control-ready wiring. - Balanced performance and power consumption with a rated current of 2.94 A and power draw of 35.28 W, providing predictable electrical load for system design. - High rotational speed of 5300 RPM for rapid air circulation where quick cooling response is required. - Measured noise level of 64 dBA to help set realistic expectations for audible operation in equipment enclosures. Key specifications: - Model: bfb1012eh. - Connection: 4 wire. - Size: 97 x 94 x 33 mm. - Nominal voltage: 12 V DC. - Voltage operating range: 7.0 to 12.6 V. - Current: 2.94 A. - Power: 35.28 W. - Speed: 5300 RPM. - Airflow: 46 cfm. - Static pressure: 2.814 inches H2O. - Noise: 64 dBA. Compatibility and practical notes: - Intended for use in 12V DC systems and devices designed to accept a fan with a 97 x 94 x 33 mm envelope and a 4 wire connection. - Verify electrical supply can provide up to 2.94 A at the chosen operating voltage and confirm mounting dimensions before installation. - Suitable for applications that require both airflow and static pressure rather than low-noise operation, given the 64 dBA sound level. Typical use scenarios: - Server cabinets and network equipment enclosures where high airflow and pressure are needed to move air through rack components and filters. - Power electronics and industrial control enclosures that require compact fans to dissipate heat from power supplies and drivers. - 3D printer or CNC machine enclosures and cooling ducts where a compact, powerful fan helps control internal temperature during extended runs. This model offers a compact form factor, strong airflow and pressure, and clear electrical specifications to support reliable integration into 12V cooling systems.
