180-49 AC Centrifugal Blower Fan | Industrial Centrifugal Fan 180mm
The Hongbo 180-49 AC centrifugal blower fan is an industrial-grade forward or backward curved blade fan designed for directed, high-pressure airflow in HVAC systems, equipment cooling, and industrial ventilation applications. Unlike axial fans, this centrifugal blower fan 180 moves air perpendicular to the inlet, generating higher static pressure for effective performance in ducted or restricted airflow installations. It features a plastic PA66 impeller, IP44 protection, and insulation class F construction.
Key Features
- Centrifugal Airflow Design: Moves air at 90° to the inlet axis, producing higher static pressure than axial fans; suited for ducted systems and applications with airflow resistance.
- Plastic PA66 Impeller: High-strength polyamide impeller provides good chemical resistance and dimensional stability under sustained operation.
- IP44 Protection Rating: Protected against solid objects greater than 1mm and water splashing from any direction; suitable for semi-exposed industrial environments.
- Insulation Class F: Motor windings rated for continuous operation at elevated winding temperatures, supporting long-duty-cycle industrial applications.
- CCC and CE Certified: Meets China Compulsory Certification and European CE requirements for industrial electrical equipment.
- AC Power Operation: Operates on standard AC voltage; compatible with single-phase industrial power supplies.
- Compact Blower Format: Self-contained blower unit suitable for integration into equipment housings, duct connectors, and ventilation assemblies.

FAQs
When should I use a centrifugal fan instead of an axial fan?
Centrifugal fans are the preferred choice when airflow must overcome resistance — such as in ducted systems, filter assemblies, or equipment with restricted outlet paths. Axial fans are better suited for free-air or low-resistance applications.
What does the IP44 rating mean for this fan?
IP44 means the fan is protected against solid particles larger than 1mm and against water splashing from any direction. It is suitable for use in industrial environments where light moisture or dust exposure is possible.
What voltage options are available?
Available AC voltage configurations vary by model. Please contact our sales team with your power supply specification for the appropriate model recommendation.
Do you support OEM orders?
Yes. We support customization of voltage, blade type, rotation direction, lead wire, and packaging. Contact our sales team with your requirements.
What is the minimum order quantity?
MOQ varies by model and configuration. Please contact us directly for details.
