- Product Introduction
The centrifugal cooker hood fan serves as the core airflow component in modern kitchen ventilation. Utilizing high-speed rotation and forward-curved impellers, it continuously pulls grease-laden air, smoke, and moisture away from cooking surfaces through ducting networks.
Unlike axial fans, these centrifugal units are specifically built to handle heavy static pressure resistance caused by complex internal baffle filters, charcoal filters, and multi-meter exhaust pipes.

Key Performance Capabilities
High Static Pressure Extraction
Aerodynamically matched scroll housings and impeller blade pitch deliver strong static pressure. This prevents backdraft and suction loss when ductwork is long or fitted with restrictive filtration.
Dynamic Balance & Acoustic Optimization
Each metal or plastic impeller undergoes automated dynamic balancing to mitigate mechanical vibration. Smooth air entry bell-mouths reduce internal air turbulence and low-frequency noise emissions.
Motor Durability in Harsh Air Environments
Motors feature enclosed ball bearings, internal thermal overload protectors, and anti-grease sealings. These design elements protect copper windings from high ambient heat and accumulated vaporized oil.
Energy Efficiency Options
Available with high-efficiency BLDC motor platforms that lower electrical power consumption while enabling smart features such as automatic constant airflow compensation.
