Zeta Plus U2 & U2W Utility Series filter cartridgesare specifically designed to provide high efficiencyand cost effective filtration of dielectric oils for thepower generation industry. U2 grades remove par-ticulate and lower levels of moisture while U2Wgrades have been optimized to remove higher levelsof moisture together with particulate contamination.

ApplicationsDielectric Oils - Fuels - Hydraulic Fluids - LubricatingOils - Machine Cutting Tool Oils - Machine Oil -Quenching Oil - Turbine Oil

CompositionThe U2 and U2W grades are composed of celluloseand microfibers with specially selected inert filteraids and charge enhancing resin. The U2W gradesare constructed with an additional high capacity wa-ter absorbing media. Both grades provide reliablefiltration even under the most demanding operatingconditions. Zeta Plus U2 and U2W cartridges areavailable in two cartridge heights, single or double,for easy installation and removal. Features includeoptional Zeta Lift (patent pending) handles to limitcontact with oils, and water impervious foil packag-ing to prevent absorption of atmospheric moistureprior to use.
