VF Model Features
Material Properties
The VF series is widely used in unit canteens, hotels, restaurants, and other public catering places for kitchen exhaust, smoke extraction, and ventilation. The fan is designed to handle air containing oil fumes, with no viscous substances, dust/hard particles ≤150mg/m³, and medium temperature ≤80℃.
Benefits
· Grease-Resistant Design: The optimized impeller and casing with cleaning windows reduce grease buildup and simplify maintenance.
· Energy-Efficient Operation: The permanent magnet motor and inverter enable variable speed control, matching airflow to actual demand and reducing energy consumption.
· High Static Pressure: The multi-blade design provides strong static pressure to overcome long duct runs in commercial kitchen exhaust systems.
·
Fan Structure
The fan features an integrated steel casing with a side-mounted cleaning window. The impeller is made of anti-stick materials to minimize grease adhesion. The permanent magnet motor is directly coupled with a dedicated inverter for speed regulation.
Model Selection
The series covers models from 5A to 8A, with power ranging from 3kW to 22kW and speeds from 600 to 1100r/min. All models come standard with permanent magnet motors and dedicated inverters.
