The vacuum pumping technology for these Alcatel Adixen ACP 40G ACP40G rebuilt refurbished compact dry roughing vacuum pumps is based on a frictionless multi-stage roots design. These Alcatel Adixen ACP40G 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 improved ACP dry vacuum pumps offer a reduced cost of ownership (COO) and require an overhaul only every 22,000 hours.
These Alcatel Adixen ACP rebuilt refurbished pumps include a single-phase integrated frequency converter with built-in instant voltage range selection. This allows these pumps to be smart and operate on any bbbbb voltage from 90 to 254 VAC at 50 or 60 Hz (with no motor setting changes required) while the rotational speed and pumping speed of the pump remains constant. This is a big selling point for OEM applications, if your tool or instrument is  the ACP pump can be used in any country or bbbbbbbb that has 90 to 254 VAC 50 or 60 Hz wall plug.
