DJF（c）百叶窗拢风筒排风机（摆转重锤式打开机构）

DJF（c）系列百叶窗式拢风筒排风机（摆转重锤打开机构）
DJF（c) series Shutter Cone Fan ( Swung drop hammer Opening system)

合理的喇叭口设计，增加抽风力，风量大、排风量稳定；采用铝合金百叶窗，重量轻、有效提高室内美观度；
Reasonable cone design, improving exhaust power. Large air volume, Adopt aluminum alloy shutters, light weight and attractive.

百叶窗加有辅助开启机构，百叶窗开启灵活、角度合理、风阻小、提率，比同等产品更加节能；
Added with Swung Drop Hammer opening system,flexible opening,reasonable open angle,lower wind resistence,higher ventilation efficiency, save much more energy than the similar fan.

扇叶采用克虏伯自洁不锈钢材料经模具冲压成型制成，不挂灰、外形美观；特殊加强风扇形状设计，风量大、不变形、不断裂、风量始终如一；不锈钢厚度为1.2mm、表面光洁度：BA
Fan blade is made of Krupp stainless steel by punch forming. no dust, attractive and durable. Special blades shape design ensure large air volume, no deformation, no broken, keeping big air volume all the time. Thickness 1.2mm, surface finish BA grade.

皮带轮均采用高强度铝镁合金压铸制成，重量轻，耐腐蚀性能强，减轻扇叶重量；特殊三根加强筋皮带轮设计，表面经过喷砂处理，提高美观度，消除内应力，有效提高了自身强度，永无断裂；
Fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of propeller, high corrosion resistance. Special three reinforced ribs pulley design. Sand blasting treatment for attractive appearance, eliminate internal stress to improve its own rigidity and stability, never broken.

风机轴承均采用法国进口双列轴承，特殊的防水设计，使水不能进入轴承，强度高、噪音小、寿命长、免维护；
Fan bearing adopts imported double-row bearing with special waterproof design. High strength, low noise, free maintenance and long service life.

扇叶均经过的电脑动平衡测试仪校正，使风机运行平稳、降低噪音、增强稳定性、延长使用寿命。
Fan blades are adjusted by intelligent dynamic-balance tester, ensure smooth running, low noise,strong stability and long service life.

2011年开始风机均采用热镀锌立柱、热镀锌保护网，今后使用过程中不生锈；并提高标准件档次，使其不生锈。
Adopt hot-dip galvanized blades support and safe net since 2011, improve standard parts quality to ensure no rust.

风机完全改为数控流水化生产，准确掌握产品质量、外形美观。
