RKC 250 D3 ErP outdrawn tc

Product marked with this symbol has an AC motor. An induction motor is an electric motor were the rotor speed is asynchronous with the input voltage frequency.

This product is compliant with the Lot 6 directive (1253/2014) and approved for use in the EU and EFTA, also after 2018.

RKC是为圆形管道所设计的直流离心管道风机，结构紧凑，容量大，操作噪音低，可以安装在任何区域。RKC风机配备了前曲式叶轮，不仅耐高压，还适应长管道运行。这些风机配备了镀锌钢坚硬外壳，具有耐湿性，可应用于户外设施。马达免于维护，由热敏开关防止温度过高。叶轮只需偶尔清洗，RKC转位式的设计使清洗变得极为方便。所有风机配线完整，并且将被安装在密封的单元内。建议不要使用这些风机来输送研磨粉，煤烟或其他类似物质。RKC具有10种尺寸。
