NEW Alcatel Adixen ACP28G ACP 28G Dry Vacuum Pump For Pumping Traces of Corrosive Gas PN V6GATSFABF
The vacuum pumping technology for these NEW Alcatel Adixen ACP 28G ACP28G compact dry roughing vacuum pumps is based on a frictionless multi-stage roots design. These Alcatel Adixen ACP28G dry pumps are specially designed for pumping traces of corrosive gas and therefore require an inert gas purge which protects the pump bearings. The Alcatel Adixen ACP series pumps are optimized for operation without lubricants inside the pumping module. The benefits of multi-roots dry pumps include oil-free and particulate-free dry vacuum, e.g., unlike their counterparts, the dry scroll pumps which generate tipseal dust and the oil-sealed rotary vane pumps which suffer from hydrocarbon vapor backstreaming. The new and improved ACP dry vacuum pumps offer a reduced cost of ownership (COO) and require an overhaul only every 22,000 hours.

ACP 15G Compact Dry Roughing Pump, specially designed for pumping traces of corrosive gases

The increase in erosion rate due to pumping would be determined by subtracting the no pump trace from the pumping traces.

Also used in electronics and science, see below:
