The hydro-dry filter elements remove up to 80% of the free water present in the oil.
The hydro-dry elements use the WR filter media, working by absorption and ensuring a high water retention capacity.
To get the maximum water removal efficiency the hydro-dry elements must be used at constant flow rate and low and constant pressure, i.e. the ideal use is in a off-line filter or in a filtration trolley.
Thehydro-dry elements remove also the solid contamination (ß21(c) > 1.000), but we recommend that the main part of solid contamination is removed upstream by a dedicated return filter. The hydro-dry elements are available in standard dimensions, to fit standard filter housings. clogging indicator set at 130 kPa (1,3 bar) on the filter housing is recommended for proper replacement of the clogged element.
