This Oil Mist Eliminator is specially designed for applications involving frequent cycling of high pressure operation and is mainly dedicated to 2015 and 2021 Series Alcatel Adixen rotary vane vaccum pumps. This Alcatel Adixen Oil Mist Filter Eliminator stops oil mist from escaping from the exhaust port, mainly when pumping between atmosphere pressure and 1 mbar (1 mTorr). Oil mist eliminators retain oil mist contained in the exhausted gases with a high level of separation; an internal over pressure valve prevents exceeding the maximum permissible exhaust pressure. This OME 25 HP+ Oil Mist Eliminator incorporates the same design as OME 25 HP but with a more efficient cartridge. It is the next step toward completely oil free exhausted gases. Supplied with filter element, O rings, one KF25 centering ring, and one clamp. This OME25HP+ (OME 25 HP+) Alcatel Adixen Oil Mist Eliminator uses replacement cartridges (Alcatel Part Number 107494) located on this website.
