|---|---|
| Fan family | High-speed brushless DC axial fan |
| Dimensions | 120x120x25mm |
| Rated voltage | 12V DC |
| Published rated current | 0.56A; verify startup demand and supply margin on the approved sample |
| Published speed | 4400RPM |
| Published airflow | 135.5CFM nominal free-air value; not the guaranteed airflow through a restricted enclosure |
| Static pressure | No numeric pressure point is asserted here; validate the operating point against system resistance |
| Noise | No universal dBA value is asserted here; high-speed acoustic performance must be checked in the actual installation |
| Power reference | Approximately 6.72W from the published 12V and 0.56A rated values; confirm approved tolerances before design release |
| Bearing type | Dual ball bearing construction |
| Signal / wiring | A 4-pin PWM interface is not asserted for this model. Confirm lead count, polarity, optional feedback requirement, cable, and connector on the approved drawing |
| Material / flammability | Housing and impeller material grade, including any UL94 classification, must follow the approved production specification; no universal grade is asserted on this page |
| Best-fit buyer intent | High free-air cooling for 12V power electronics, inverters, servers, and control equipment after pressure, temperature, current, vibration, and acoustic validation |
| Manufacturer and quality review | SENSDA ELECTRONICS LIMITED / SXDOOL. ISO 9001:2015 quality-management documentation, OEM/ODM cable and connector requirements, Dynamic Balancing, and 100% End-of-Line Testing can be reviewed against the approved production control plan. |
Model-specific engineering FAQ
What does 135.5CFM mean for a restrictive server or inverter airflow path?
It is a nominal free-air reference, not the final equipment airflow. Establish the pressure loss of the inlet, heat sink, component field, filters, and outlet, then verify temperatures and delivered airflow with an approved sample.
Is this 0.56A high-speed model the same as the 0.80A 4-pin PWM product?
No. This page identifies the 0.56A, 4400RPM, 135.5CFM high-speed variant. The 0.80A product is a separate 143.1CFM 4-pin PWM option with a different electrical interface and must not be substituted without controller review.
How should the 12V supply be qualified for this high-speed fan?
Use the published 0.56A value for initial budgeting, then confirm startup current, supply tolerance, voltage drop through the harness, connector rating, polarity, and transient behavior on the approved sample. Do not size the supply from airflow alone.
Which tests matter most before using this fan continuously in industrial equipment?
Run the fan in the real orientation and restriction path while recording component temperature, airflow or pressure, current, startup behavior, vibration, acoustic result, cable temperature, and restart behavior after representative thermal cycling.
Continue with the DC axial fan family, use the fan selector, review system-airflow application guidance, compare the 12V 0.80A 4-pin PWM variant, or submit a model-specific RFQ.
