Effective utilization of compressed heat which is own high temperature uniformity technology has given this dry pump series a high durability in the hard processes of CVD, etching etc. In the light processes, approximately up to 70% of electric power consumption reduction is possible by having the ECHO-SHOCK on the pump. CE marking is available for all series (optional).
- LR series: Uniformity of low temperature distribution. The optimum pump for the evacuation of LL chamber, in addition to the PVD processes, in which reduction of exhaust time is important to up the throughput.
HR series: Uniformity of high temperature distribution. It is possible to exhaust the sublimates generated by CVD and etching processes in a gaseous state.
Noise reduction PDR-180C: 74dB > LR180: 68.5dB
Pump withstands power interruptions of up to 500ms duration.
CE marking is available upon request.
- Evacuation of activated gas (CVD and etching, etc)
Evacuation of inert gas (PVD, evaporation, heat treatment processes, etc)
Reduction of exhaust time for LL chamber (LR series)
Evacuation of gases on the process which generate powders (Si crystal growing furnaces, etc)
Backing pump for turbo-molecular pumps, mechanical booster pumps, etc

| *1: | With the HR300,HR600 and HR1200,do not allow the repeated pumping operation at the suction pressure more than 200Pa. There is possibility pump temperature will exceed the upper limit of the setting point and the interlock will run. |
| *2: | The standard suction port flange is JIS flanging flange will be suction port flange in the case of CE marking. NW flange is available as the option even CE marking is not required. |
