Multi-Stage Roots Type Dry Vacuum Pump
Power Saving Attachment
ECO-SHOCK
アルバック
ECO-SHOCK is a revolutionary dry pump accessory that can dramatically reduce power consumption
by attaching to the dry pump exhaust line
by attaching to the dry pump exhaust line
Features
- Energy saving
Max.80% reduction of power consumption of the dry pump.
Also, ECO-SHOCK enable to save the cost of air conditioning because it helps to reduce heat generation from the pump.
* ECHO-SHOCK is not available for the pump which evacuates flammable and
toxic corrosive gas spiecies. - Pump performance improovement
Reduce the noise level while pumping.
No reduction of pumping performance at all pressure range.
Most effective for long continuous pumping time less than 1000Pa.
*ECO-SHOCK is capable to use with the dry pump that exhaust port can be in vacuum condition. - Simple installation
Applications
- Dry vacuum pumps for evacuating iner gases such as air, nitrogen or argon.
- Dry vacuum pumps used with sputtering or loading / unloading chambers.
