多级罗茨型干泵

LR 系列

LR421-T

アルバック

干泵LR系列,根据独有的高温均热化技术,有效利用压缩热,实现了在CVD,蚀刻等硬工艺中的高耐久性。在轻工艺中,与ECO-SHOCK的组合最多可节省约80%的电力。 另外,提高了维护性和降低了噪音,全部型号CE对应可能(可选)。关于ECO-SHOCK的详细信息,请参考关联信息。

特点

  • LR系列:低温领域
    不单是惰性气体,还特别适用于装载和卸载室中的排气,缩短排气时间以增加产量。
  • HR系列/UR系列:高温领域
    CVD,蚀刻等产生的可升华的废气物质可以在气体状态下排出。
  • 1000毫秒内瞬时中断。
  • 符合CE标志(可选)。

用途

  • 活性气体(CVD、干刻等)
  • 惰性气体(溅射,蒸发,热处理等)
  • 放入取出室排气时间缩短(LR系列)
  • 产生粉尘的工艺的排气(Si单晶体上升等)
  • 作为辅助排气泵(涡轮分子泵、机械增压泵的辅助排气)

*Please specify voltage at the time of ordering.
*LR pump designed for low operating temperature of the pump body. The HR is for high temperature pump body operation. While the UR series is for Ultra High pump body temperature.
*The HR300, HR600, HR1200,UR600,UR1200,UR1800 and UR3601-TT models should all be operated below 200Pa (1.5 Torr).
*The LR3601-R/TR/TTR is an improved exhaust performance model in the high-pressure area.

*MBP of LR300, LR600, LR1200, LR1800, can choose the existence of a surface treatment.
*Additionally, a pump with gasballast use is possible to quote. Please contact us for the selection and quotation.
