Small Centrifugal Fan Manufacturer DC, AC & EC Blowers for OEM
High static pressure · Compact design · Full customization · UL/CE/RoHS
FANACDC engineers small centrifugal fans (blower fans) for industrial equipment, electrical enclosures, telecom, and compact cooling applications. Backward-curved & forward-curved impellers, dual ball bearings, IP68 ready.
What is a Small Centrifugal Fan?
A small centrifugal fan (blower) draws air axially into the impeller and discharges it perpendicularly (90°) at higher static pressure. Unlike axial fans, centrifugal fans overcome system resistance — filters, grilles, long ducts, or compact electronics. Ideal for industrial cabinets, telecom shelters, medical devices, and 3D printers.
- High static pressure for restricted airflow
- Directional outlet for duct integration
- Compact footprint: 50mm to 200mm frame sizes
- AC, DC and EC motor options
Centrifugal vs Axial: Quick guide
| Axial fan | High airflow, low pressure |
| Centrifugal fan | Lower airflow, much higher static pressure |
Use centrifugal when air must pass through filters, heat exchangers, or narrow channels.

How to Choose the Right Small Centrifugal Fan
- 1. Voltage & power supply 12V/24V/48V DC for battery or control board; 110V/230V AC for direct line power.
- 2. Static pressure requirement Use centrifugal fans when system pressure drop > 40 Pa (filters, dense heatsinks).
- 3. IP rating & environment IP44 indoor; IP55 outdoor/rain; IP68 washdown or submersible.
- 4. Bearing type Dual ball bearings for long life (70,000 hrs) and high temp; sleeve for budget/low cycles.
- 5. Speed control PWM or voltage regulation for DC/EC fans; AC fans can use external triac control.
- 6. Connector & integration We match your existing wiring harness – free engineering support.
Quality Control & Reliability
- RPM & current tolerance test
- Dielectric strength (Hi-Pot)
- Noise measurement (semi-anechoic chamber)
- Insulation resistance
- Lifecycle sample test (70k hrs L10)
- IP rating verification
