DJF（e）系列雙門式攏風(fēng)筒排風(fēng)機(jī)

DJF(e) series Butterfly Cone Fan

采用前置雙門打開(kāi)機(jī)構(gòu)，風(fēng)阻小、密閉好、效率高；加長(zhǎng)喇叭口設(shè)計(jì)，提高抽風(fēng)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(fēng)機(jī)雙門關(guān)閉時(shí)加有橡膠密封裝置，當(dāng)多臺(tái)風(fēng)機(jī)根據(jù)環(huán)境情況，不同時(shí)啟動(dòng)時(shí)，有效避免空氣回流，大大提高運(yùn)行效率，與同功率風(fēng)機(jī)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(fēng)機(jī)特殊的風(fēng)扇形狀設(shè)計(jì)使其可自行清潔以達(dá)到**效率，扇葉采用克虜伯自潔不銹鋼材料經(jīng)模具沖壓成型制成，風(fēng)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(fēng)機(jī)扇葉均經(jīng)過(guò)的電腦動(dòng)平衡測(cè)試儀校正，**風(fēng)機(jī)運(yùn)行平穩(wěn)、降低噪音、增強(qiáng)穩(wěn)定性、延長(zhǎng)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(fēng)機(jī)均采用熱鍍鋅立柱、熱鍍鋅保護(hù)網(wǎng)，**今后使用過(guò)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(zhǎng)3倍；Use B-V belt, lifespan is 3 times longer than A-V belt. 

風(fēng)機(jī)改為數(shù)控流水化生產(chǎn)，準(zhǔn)確掌握產(chǎn)品質(zhì)量，達(dá)到國(guó)際同行業(yè)的**水平，外形美觀。Complete new CNC production line improved fan quality up to grade, aesthetic appearance.
