DC fans are brushless cooling fans powered by a low-voltage DC source โ ideal for any equipment running on battery, solar, or a DC bus. With built-in driver electronics they offer precise PWM speed control, tachometer feedback, and 30%+ better energy efficiency than AC fans. Hongbo manufactures a full range of brushless DC axial fans โ 25mm to 200mm in 12V, 24V and 48V โ engineered for a 50,000โ70,000 hour service life with locked-rotor protection and reverse-polarity protection as standard. Custom voltage (5Vโ60V), connector, PWM curve, and IP68 waterproofing are available for OEM projects.

What Our Clients Say
A charger maker needed fans surviving rain and dust on cabinet intakes. Our HB12038-DC IP67 ran 2 years outdoors with no sealing failures.
EV Charger OEM
Charging Infrastructure | Germany
Urban noise limits ruled out the previous fan. Our sleeve-bearing HB9225-DC dropped node noise below the local 40 dB-A threshold.
5G Equipment Integrator
Telecom Equipment | South Korea
An imaging OEM required near-silent cooling near patients. Custom low-RPM HB8025-DC met their acoustic spec without thermal compromise.
Medical Device OEM
Diagnostic Equipment | United States

Frequently Asked Questions
No fixed MOQ. We accept orders of any size โ from a few pieces for prototyping up to container-scale volume production. Many long-term customers start with a small trial order of DC Fans to validate fit before scaling up. Tell us your quantity and we’ll quote accordingly.
Yes โ samples are free. You only cover the courier cost (typically $30โ60 via DHL/FedEx, 3โ5 days door to door). Standard-model samples dispatch within 7 days of your request so you can evaluate real performance before committing.
We accept T/T (telegraphic transfer / bank wire). For new orders the standard arrangement is a deposit with the balance before shipment; exact split is confirmed on the proforma invoice. Terms can be discussed for established repeat customers.
All Hongbo DC Fans carry a 24-month warranty from the shipment date. Verified manufacturing defects are replaced free of charge in your next shipment or credited. Our field return rate is below 0.5%, and we run full root-cause analysis on any batch-level issue.
Standard models ship from stock within 7 days. Bulk orders of 5,000โ20,000 units take 25โ35 days. We confirm a firm ship date on the proforma invoice and send production progress photos at the midpoint of manufacturing.
Yes. You’re welcome to send BV, SGS, TรV, or your own QC team to inspect before shipment. We also provide our own AQL 1.0 inspection report and 100% Hi-POT test records with every shipment at no extra charge
A DC fan runs on low DC voltage (12V/24V/48V) with a brushless motor and built-in electronics, enabling PWM speed control, tachometer feedback, and 30%+ better efficiency. AC fans run directly from mains at fixed speed. Choose DC when your equipment has a DC rail or needs variable speed; see ourย AC Axial Fanย andย EC Fanย pages.
Yes. Most support 25 kHz PWM by default. We can customize PWM frequency (1โ30 kHz), duty-cycle response curve, and minimum-speed lockout. FG and RD tachometer outputs are available for fault monitoring.
Yes โ we routinely build for 5V, 19V, 36V, 56V, and 60V. Send your voltage spec and operating environment for a custom winding quote.
Standard models are IP54. IP55/IP67/IP68 housings are available for outdoor, EV charging, and energy-storage applications. IP68 versions are validated for 1m submersion.
Yes โ see ourย Fan Guardย andย Fan Filterย categories. Matched assemblies available for every standard frame size.
