The vacuum pumping technology for these Pfeiffer Adixen ACP 28CV ACP28CV compact dry roughing vacuum pumps is based on a frictionless multi-stage roots design. These Pfeiffer 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 pump 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.

The CV (Condensible Vapor) ACP models are specificaly designed to avoid vapor condensation within the pumping module with 3 features: A high gas ballast flow to help dilute condensable gasses, an external drainable silencer to remove excess liquid from the lowest point of the exhaust stage, and a gas purge to protect bearings and seals.

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 input 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 mobile the ACP pump can be used in any country or location that has 90 to 254 VAC 50 or 60 Hz wall plug.

The specifications for the Alcatel Adixen ACP 28 ACP28 dry vacuum pump is a 16 cfm (27 m3/hr) pumping speed, 22.5 mTorr ultimate pressure, can operate on input voltages from 90 to 254 VAC 50-60 Hz, air cooled, includes integrated digital timer and manual gas ballast, and has a KF25 inlet & KF25 exhaust.
