190FLW AC Centrifugal Blower Fan | Industrial Centrifugal Fan 190mm
The Hongbo 190FLW is a compact backward-curved AC centrifugal fan designed for HVAC, industrial ventilation and equipment cooling. It delivers airflow up to 580 mยณ/h and static pressure up to 335 Pa, with 220V and 380V configurations available.
Key Features
- Centrifugal Airflow Design:ย Moves air at 90ยฐ to the inlet axis, producing higher static pressure than axial fans; suited for ducted systems and applications with airflow resistance.
- Plastic PA6+25%GF Impeller:ย High-strength polyamide impeller provides good chemical resistance and dimensional stability under sustained operation.
- IP44 Protection Rating:ย Protected against solid objects greater than 1mm and water splashing from any direction; suitable for semi-exposed industrial environments.
- Insulation Class F:ย Motor windings rated for continuous operation at elevated winding temperatures, supporting long-duty-cycle industrial applications.
- Certification: CE and CQC certified configurations available. Manufactured under an ISO 9001 quality management system.
- AC Power Operation: Operates on standard AC voltage; available in 220V and 380V AC configurations..
- Compact Blower Format:ย Self-contained blower unit suitable for integration into equipment housings, duct connectors, and ventilation assemblies.
