The HFJZ-A craftsman kitchen fan is a square-housed ultra-quiet multi-blade centrifugal fan specially designed for kitchen exhaust. It was engineered to meet the demand for low-noise kitchen fans in modern kitchens and the exhaust requirements of communal ductwork. Compared to conventional multi-blade fans, it offers advantages such as higher pressure and lower noise levels. Moreover, it features a high static pressure design to tackle long ductwork and high resistance typical of modern kitchen setups.
The fan features a double-layer volute casing design, with the inner volute constructed from welded perforated plates. A 3cm-thick layer of high-temperature-resistant sound-absorbing cotton fills the space between the inner and outer casings, effectively eliminating noise generated by gas flow. Both inlet and outlet can be optionally equipped with crafted silencers, boasting an exquisite appearance.
Perfectly suited for kitchen air supply in public venues such as canteens, hotels, restaurants, and other public establishments.
Optional accessories: craftsman silencers and vibration dampers.
