172×150×51mm AC Axial Fan | Industrial 17251 Cooling Fan
The Hongbo 172×150×51mm AC axial fan is a high-airflow industrial fan designed for large-format control cabinets, ventilation panels, and equipment requiring substantial forced-air cooling. This 172mm axial fan delivers 277–336 m³/hr (160–198 CFM) and operates across 110V, 220V, and 380V AC inputs at 50/60Hz. It is built with an aluminum alloy frame, a PBT thermoplastic impeller, and supports both ball and sleeve bearing configurations for flexible deployment.
Key Features
- Aluminum Alloy Frame: Rigid structural housing suitable for flush-panel and bracket mounting in industrial enclosures.
- High Airflow 277–336 m³/hr: Delivers strong air movement for enclosures with high heat-generating components such as drives, transformers, and rectifiers.
- Three-Phase and Single-Phase Voltage: Available at 110V, 220V, and 380V AC, covering single-phase and three-phase power supply configurations.
- PBT Thermoplastic Impeller: UL94-V0 rated; resists ignition and retains dimensional accuracy under sustained airflow loading.
- Thermal-Protected Motor: Shaded pole induction motor with built-in thermal protection; automatically limits overheating risk during continuous operation.
- 50,000-Hour Service Life (Ball Bearing): Ball bearing variant rated for extended duty cycles; sleeve bearing available for standard applications.
- UL and CE Approved: Complies with North American and European safety standards for industrial equipment.

FAQs
What makes the 172mm size suitable for industrial applications?
The 172×150×51mm format fits standard ventilation cutouts in industrial panels and delivers airflow levels suited for enclosures with high thermal loads, where smaller fans would be insufficient.
Which voltage is most commonly ordered?
220V single-phase is most common for export markets. 380V three-phase models are frequently ordered for industrial plant applications in Asia and Europe.
What is the difference between sleeve and ball bearing variants?
Ball bearing models are rated for 50,000 hours at 40°C and perform better in high-temperature environments. Sleeve bearing models are a cost-effective option for standard-duty applications.
Do you support OEM orders?
Yes. We support customization of voltage, bearing type, lead wire, and packaging. Contact our sales team with your specifications and volume requirements.
What is the minimum order quantity?
MOQ varies by model and configuration. Please contact us directly for details.
