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. Supplied with filter element. This OME40S (OME 40 S) (Adixen Part Number 104887) Oil Mist Eliminator uses replacement cartridge P102595 located on this website.
