SXDOOL 8038 high-pressure DC fan for dense airflow paths
Engineering summary: This 80x80x38mm D/H platform is the high-pressure branch of the 8038 family. Its 7500-9000RPM catalog grades target compact systems with dense heat sinks, filters, or narrow flow passages and must not be confused with the quieter 4500-6000RPM M/L page.
| Product / model reference | SXD8038D / SXD8038H high-pressure grades |
|---|---|
| Fan family | Brushless DC axial fan |
| Dimensions | 80x80x38mm |
| Rated-voltage choices | 12V / 24V / 48V DC |
| Bearing selection | Sleeve or ball-bearing family options; the complete voltage, speed, bearing, cable, connector, and signal suffix must follow the approved production drawing |
| Signal options | Auto-restart, PWM speed input, FG speed feedback, and RD alarm are configuration-dependent options; none is included unless shown on the approved interface specification |
| Material / flammability boundary | Catalog family reference: plastic frame and impeller, UL94V-0. Final resin, colour, and compliance documentation must match the approved production specification |
| Catalog operating environment | -10 to 70C operation, 35%-85%RH; -40 to 80C storage, 35%-85%RH. Validate application-specific derating and condensation risk |
| Application fit | High-density electronics, server subsystems, power supplies, and filtered industrial air paths that require a high static-pressure reserve in an 80mm frame. |
| Page differentiation | This page covers the 7500-9000RPM D/H grades. For lower current and acoustic demand, compare the 4500-6000RPM M/L standard-output page. |
| 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. |
| Source and qualification boundary | DC family values are catalog-typical under nominal voltage. Catalog noise is referenced one meter from the air intake. Current approved model documents and samples govern the final specification. |

| SXD8038D | 24V | 1.50A | 9000RPM | 124.0CFM | 50.0mmH2O | 67dBA |
| SXD8038D | 48V | 0.80A | 9000RPM | 124.0CFM | 50.0mmH2O | 67dBA |
| SXD8038H | 12V | 1.60A | 7500RPM | 105.0CFM | 35.0mmH2O | 63dBA |
| SXD8038H | 24V | 0.80A | 7500RPM | 105.0CFM | 35.0mmH2O | 63dBA |
| SXD8038H | 48V | 0.45A | 7500RPM | 105.0CFM | 35.0mmH2O | 63dBA |
Engineering release rule: Catalog values are typical reference data under nominal test conditions. The current approved drawing, controlled datasheet, sample label, and validated equipment test govern the final purchasable configuration.
Model-specific engineering FAQ
What system evidence justifies selecting SXD8038D rather than SXD8038H?
Select the D grade only when the measured system curve and thermal target need the additional 50.0mmH2O and 124.0CFM catalog capability. If the H grade meets temperature limits at 35.0mmH2O, its lower current and speed may provide a better electrical and acoustic margin.
How large should the power-supply margin be for a 12V 9000RPM 8038 fan?
The catalog rated current is 2.80A at 12V for SXD8038D, but the supply must also tolerate startup and transient demand. Confirm the approved startup-current profile, connector rating, wire gauge, voltage drop, protection strategy, and the number of fans starting simultaneously.
Why can a 124CFM high-pressure fan still underperform behind a restrictive filter?
Free-air CFM and static-pressure capability describe different points on the fan curve. A loaded filter, small louver, blocked inlet, or recirculating outlet can move the operating point below the required airflow, so the complete resistance path and dirty-filter condition must be tested.
Which mechanical risks increase at 7500-9000RPM?
Fastener retention, guard clearance, inlet turbulence, panel resonance, cable restraint, fan orientation, and dynamic vibration become more important. Validate the approved sample in the production mounting stack and inspect the structure after representative thermal and vibration exposure.
