The DC Blower Fan 7030 is a 75×75×30 mm DC brushless centrifugal blower series from Shenzhen Yunfan Power. It operates on 12 / 24 VDC with sleeve and ball bearing options, running 2500–5000 RPM and delivering up to 12.31 CFM with noise levels from 33.3 dBA. Its right-angle centrifugal outlet concentrates airflow through heatsinks, ducts and filters, ideal for projectors, storage nodes, telecom rectifiers and energy-storage cabinets. Wholesale pricing and OEM customization are supported.
Key Features
- High static pressure airflow — The centrifugal impeller exhausts at a right angle, pushing air through heatsinks, ducts and filters where axial fans stall.
- Function options: AS / FG / RD / PWM / TC — Auto restart, tach signal, rotation detection and PWM/TC speed control supported.
- Bearing options for every duty — Sleeve bearing for cost-sensitive builds; ball bearing for long-life 24/7 and any-angle mounting.
- Certified and procurement-ready — CE certified and RoHS compliant; certificates available with shipment.
- OEM / ODM customization — Custom voltage, speed, connectors, lead wires and private labeling from low MOQ.
Applications of the YUNFAN DC Blower Fan Series
- Projectors & optical engines — Directed cooling for DMD/LCD optical blocks in slim enclosures.
- Servers & storage nodes — Focused heatsink cooling where axial fans cannot reach hot spots.
- Telecom rectifiers & energy storage — High-pressure ducted cooling for power modules and battery cabinets.
- Air purifiers & dehumidifiers — Quiet ducted airflow through filters and heat-exchange cores.
- Industrial power supplies — Cooling of dense transformer and IGBT assemblies on DC buses.
Frequently Asked Questions — DC Blower Fan 7030
What is the difference between a DC blower and a DC axial fan?
A blower uses a centrifugal impeller and exhausts air at a right angle, producing higher static pressure — the right choice for heatsinks, ducts, filters and enclosed cabinets. Axial fans suit open, low-resistance paths.
What is the difference between sleeve and ball bearing versions?
Sleeve bearing is the most cost-effective and quietest option, best for horizontal mounting. Ball bearing lasts longer, tolerates any mounting angle and higher ambient temperature — recommended for 24/7 duty.
Can I order the 7030 with custom speed, connector or function options?
Yes. Custom RPM, voltage, lead connectors and function options (FG/RD signal, PWM/TC speed control, AS auto restart) are available. MOQ starts from 100 pieces and samples are supported for testing.
What is your lead time and warranty?
Standard models ship in 7–15 days; custom orders in 20–30 days. All fans carry a 2-year warranty with lifetime technical support.
