Product Introduction
The HF Diagonal Flow Duct Fan is a hybrid ventilation solution that combines the advantages of both axial flow and centrifugal fans. It delivers high airflow at medium pressure with low noise levels, making it ideal for applications where efficient duct ventilation is required.
This fan is widely used in HVAC systems, tunnels, basements, factories, warehouses, and commercial buildings to ensure continuous air circulation, exhaust, and cooling.
Application Industries & Uses:
- HVAC and ducted ventilation systems
- Factories and production workshops
- Basements and underground structures
- Tunnels and long pipeline ventilation
- Commercial and public buildings
Features & Construction
- Impeller:
- Diagonal blade design (between axial and centrifugal)
- Ensures higher pressure than axial fans and larger airflow than centrifugal fans
- Balanced for low vibration and noise reduction
- Casing & Housing:
- Cylindrical steel housing with corrosion-resistant finish
- Compact and easy to install within ducts
- Motor:
- Direct-driven pure copper motor
- Energy-efficient and reliable for continuous operation
- Performance:
- Suitable for medium pressure, long-distance ventilation
- Delivers stable airflow with minimal noise
