Purchase Information
We support purchase inquiries for the Nidec W12E12BS11B5-07 DC Axial Cooling 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, 12 VDC supply, 1.65 A current rating, 120 x 120 x 38 mm dimensions, connector configuration and airflow direction. Speed, airflow, static pressure and wiring details should be checked against the exact -07 variant because some available listings describe the related base model rather than the complete part number.
Frequently Asked Questions
What is Nidec W12E12BS11B5-07?
It is a Nidec UltraFlo DC axial cooling fan identified by the complete model number W12E12BS11B5-07.
What voltage does W12E12BS11B5-07 use?
Available model-specific listings identify a nominal rated voltage of 12 VDC. Verify the operating voltage range on the exact fan documentation.
What is the rated current?
The available supplier listings specify 1.65 A. Confirm the rating on the actual product label before installation.
What is the nominal input power?
Using the listed 12 V and 1.65 A ratings gives a calculated input of 19.8 W. Confirm the manufacturer's specified power rating for the exact variant.
What are the dimensions of this fan?
The listed dimensions are 120 x 120 x 38 mm. Check mounting-hole spacing and clearance before replacing an existing fan.
What is the rated speed?
Available listings report approximately 6,000–6,500 RPM. The figures differ between sources, so verify the exact -07 variant before using speed as a replacement criterion.
What airflow does this fan provide?
The related W12E12BS11B5 base model is listed at approximately 197 CFM. This value should not be treated as a confirmed specification for every suffix variant.
What is the maximum static pressure?
A related base-model listing reports 1.20 inH₂O. Confirm the applicable performance curve for the exact fan model and equipment airflow path.
How many wires does the fan use?
Supplier listings identify a four-wire connector. Verify the connector and pin assignment against the actual fan or equipment documentation.
Does this fan support PWM speed control?
Four-wire fans may use an additional control lead, but the exact PWM signal requirements for W12E12BS11B5-07 should be confirmed before connecting it to a controller.
Does this fan provide tachometer feedback?
Confirm the feedback function and signal pinout for the exact -07 variant before integrating it with a monitoring circuit.
Can this fan replace another 120 mm fan?
Not automatically. Verify the complete model number, frame thickness, voltage, current, airflow direction, connector pinout and any control or monitoring requirements.
What should be checked before ordering?
Confirm model W12E12BS11B5-07, 12 VDC, 1.65 A, 120 x 120 x 38 mm dimensions, four-wire connection and compatibility with the target equipment.
