The VF series multi-blade centrifugal fan for kitchen fume extraction utilizes the XBF-C blade configuration. While the impeller is effective for kitchen fume exhaust, it is difficult to clean oil residue from it. The fan benefits from refined manufacturing techniques and extensive design and production experience. The housing includes standard cleaning windows. The unit is equipped with a permanent magnet motor and an inverter. It is widely suitable for fume exhaust, smoke ventilation, or air movement in institutional canteens, hotels, restaurants, and other public kitchens. The transmission medium is air or other non-self-igniting gases that are harmless to the human body. The medium must contain no viscous substances, operate at temperatures below 80°C, and have dust and hard particle content less than 150 mg/m³.
