220-64 AC Centrifugal Blower Fan | Industrial Centrifugal Fan 220mm
The Hongbo 220-64 AC centrifugal blower fan is a larger-format industrial-grade centrifugal blower designed for high-volume, high-pressure airflow in ducted HVAC systems and equipment cooling applications. This centrifugal blower fan 220 features a PA66 plastic impeller, IP44 protection rating, and insulation class F construction. The increased 220mm impeller diameter compared to the 180-49 model delivers greater airflow output for larger-scale industrial and commercial ventilation requirements.
Key Features
- 220mm Impeller Diameter: Larger swept area provides higher volumetric airflow and pressure compared to smaller centrifugal blowers; suited for medium-to-large ducted systems.
- High Static Pressure Output: The centrifugal blade design generates pressure significantly higher than axial fans of comparable size; effective for ducted or restricted-pathway installations.
- Plastic PA66 Impeller: High-strength polyamide material provides good chemical resistance, abrasion resistance, and dimensional stability under continuous loading.
- IP44 Protection: Protected against solid objects larger than 1mm and water splashing from any direction; suitable for industrial environments with light moisture or particulate exposure.
- Insulation Class F: Motor windings rated for continuous operation at temperatures up to 155°C, supporting demanding industrial duty cycles.
- AC Motor Drive: Uses robust AC induction motor technology for reliable, maintenance-free continuous operation.
- CCC and CE Certified: Meets China Compulsory Certification and European CE requirements for industrial electrical equipment.

FAQs
How does the 220-64 compare to the 180-49 model?
The 220-64 uses a larger 220mm impeller, delivering higher airflow and pressure compared to the 180-49. It is better suited for larger duct systems or applications with greater airflow requirements.
Is this fan suitable for outdoor installation?
The standard model has an IP44 rating, which protects against splashing water and solid objects larger than 1mm. For direct outdoor exposure, additional weather protection or a higher IP-rated model may be required. Contact us for outdoor-rated options.
What is the noise level at operating speed?
Noise levels vary by specific model and RPM configuration. Please contact us with your airflow and pressure requirements for model-specific acoustic data.
Do you support OEM orders?
Yes. We support customization of voltage, blade type, rotation direction, flanges, and packaging. Contact our sales team with your specifications.
What is the minimum order quantity?
MOQ varies by model and configuration. Please contact us directly for details.
