3M Zeta Plus U2-UW2

3M™ Zeta Plus™ U2 & UW2 Series Filters

Zeta Plus U2 and U2W Utility Series filter cartridges are specifically designed to provide high efficiency and cost effective filtration of dielectric oils for the power generation industry.<
U2 grades remove par ticulate and lower levels of moisture while U2W grades have been optimised to remove higher lev els of moisture together with particulate contamination.
The U2 and U2W grades are composed of cellulose and microfibres with specially selected inert filter aids and charge enhancing resin.
The U2W grades are constructed with an additional high capacity water absorbing media. Both grades provide reliable filtration even under the most demanding operating conditions.<
Zeta Plus U2 and U2W cartridges are available in two cartridge heights, single or double, for easy installation and removal.
Features include optional Zeta Plus Lifting Device handles to limit contact with oils, and water-impervious foil packaging to prevent absorption of atmospheric moisture prior to use.
To minimised potential for moisture re-entrainment and ensure high efficiency particulate removal, it is recommended cartridges be replaced when a differential pressure of 1.4 bar (20 psid) is reached.
