DJF（e）系列雙門式攏風筒排風機

DJF(e) series Butterfly Cone Fan

采用前置雙門打開機構，風阻小、密閉好、效率高；加長喇叭口設計，提高抽風壓力；Using advanced front double door opening device, small wind resistance, good sealing, high efficiency, lengthened cone design improve exhaust power.

外框鍍鋅板均采用275g/㎡鍍鋅層，有效避免生銹；Zinc coating weight of Galvanized sheet is 275g/㎡,avoiding rust effectively.

風機雙門關閉時加有橡膠密封裝置，當多臺風機根據環境情況，不同時啟動時，有效避免空氣回流，大大提高運行效率，與同功率風機相比，提高效率15-20%；Fan double doors closed with the rubber sealing which effectively avoid air backflow when start fans at different time. Greatly improve the operation efficiency by 15-20% compared with the same power fan.

三和風機特殊的風扇形狀設計使其可自行清潔以達到**效率，扇葉采用克虜伯自潔不銹鋼材料經模具沖壓成型制成，風量大、不變形、不斷裂、不掛灰、美觀耐用；不銹鋼厚度：1.2mm、表面光潔度：BASanhe fan blade is special designed for the biggest efficiency which made of Krupp stainless steel by punch forming. Large air volume, no deformation, no broken, no dust, attractive and durable. Thickness 1.2mm, surface finish BA grade.

風機扇葉均經過的電腦動平衡測試儀校正，**風機運行平穩、降低噪音、增強穩定性、延長使用壽命。Fan blades are adjusted by intelligent dynamic-balance tester, ensure the fan smooth running, lower vibration, less noise, increase stability.

風機均采用熱鍍鋅立柱、熱鍍鋅保護網，**今后使用過程中不生銹；Hot-dip galvanized blade support and safe net ensure never rust.

皮帶采用B型皮帶，與其他廠家的A型皮帶相比，使用壽命延長3倍；Use B-V belt, lifespan is 3 times longer than A-V belt. 

風機改為數控流水化生產，準確掌握產品質量，達到國際同行業的**水平，外形美觀。Complete new CNC production line improved fan quality up to grade, aesthetic appearance.
