Key Features
Counter-Rotating Fan Design
The dual-fan assembly uses counter-rotating impellers to support high-airflow and high-static-pressure cooling requirements.
636 CFM Maximum Airflow
The documented maximum airflow reaches 18 m³/min, equivalent to approximately 636 CFM, at the specified full-duty operating condition.
High Static Pressure
The specified maximum static pressure is 1,400 Pa (5.62 inH₂O), useful for evaluating equipment with restrictive airflow paths.
PWM Speed Control
The integrated PWM control function uses a specified 25 kHz input frequency to support compatible system-level fan speed management.
Pulse Sensor Feedback
Pulse sensor outputs allow compatible monitoring equipment to detect fan rotation and support cooling-system diagnostics.
Aluminum Frame Construction
The aluminum frame provides a rigid structure for the dual-fan assembly. The impellers use plastic classified UL 94V-0.
Integrated Motor Protection
Documented protection functions include locked-rotor burnout protection and reverse-polarity protection.
Applications
- Industrial inverter and drive cooling
- High-power electrical equipment ventilation
- Industrial power electronics cooling
- Telecommunications equipment cooling
- Server and high-density equipment airflow
- Industrial machinery thermal management
- Control system ventilation assemblies
- Replacement of compatible counter-rotating fan units
Purchase Information
We support purchase inquiries for the Sanyo Denki 9CR5748P9G001 counter-rotating DC axial fan. For bulk orders or related industrial cooling components, contact our team with your required quantity and equipment application. Before ordering, verify the complete model number, 48 VDC supply, 5.5 A rated current, 172 x 150 x 102 mm overall dimensions, dual-fan configuration, PWM control signal and pulse-sensor wiring. Because this is a counter-rotating assembly, confirm the airflow direction and inlet/outlet orientation against your existing equipment.
Frequently Asked Questions
What is Sanyo Denki 9CR5748P9G001?
It is a San Ace 172 series DC counter-rotating axial fan assembly designed for high-airflow industrial and electronic equipment cooling.
What voltage does 9CR5748P9G001 require?
The rated voltage is 48 VDC, with a specified operating voltage range of 36–72 VDC.
What are the rated current and input power?
At 100% PWM duty cycle, the manufacturer specifies a rated current of 5.5 A and input power of 264 W.
What are the overall dimensions?
The complete counter-rotating fan assembly measures approximately 172 x 150 x 102 mm. Confirm the installation clearance before ordering.
What does counter-rotating mean?
The assembly contains two fan sections that rotate in opposite directions. The inlet and outlet sections have different specified rotational speeds.
What are the inlet and outlet fan speeds?
At 100% PWM duty cycle, the specified inlet speed is 7,300 RPM and the outlet speed is 6,400 RPM.
What is the maximum airflow?
The documented maximum airflow is 18 m³/min, equivalent to 636 CFM, under the specified full-duty condition.
What is the maximum static pressure?
The specified maximum static pressure is 1,400 Pa, equivalent to approximately 5.62 inH₂O.
Does this fan support PWM speed control?
Yes. The model includes PWM speed control with a specified input frequency of 25 kHz. Confirm the control signal and wiring requirements before installation.
Does it provide fan rotation monitoring?
Yes. Pulse sensor outputs are provided for compatible fan monitoring circuits. Each fan section has its own connection requirements.
What motor protection functions are included?
The manufacturer documents locked-rotor burnout protection and reverse-polarity protection.
What is the operating temperature range?
The specified operating temperature range is -20°C to +70°C.
Can this fan replace another 172 mm fan?
Not automatically. Verify the complete model number, overall depth, counter-rotating arrangement, airflow direction, voltage, current, PWM interface, pulse-sensor wiring and mounting requirements.
What should be checked before ordering?
Confirm model 9CR5748P9G001, 48 VDC supply, 5.5 A rated current, 264 W input, 172 x 150 x 102 mm dimensions, four-wire connections for each fan section, and compatibility with the equipment control system.
