The HDU 27/27 PV-PY series of offline fine filters are especially designed for the filtration of high viscosity lubricants on wind turbine transmissions.

The large by-pass valve ensures a controlled operation of the filter system, even at very low temperatures. Oil filtration rate: 60 L/hr.

APPLICATION
ISO VG 150 - 320 cSt at temperatures up to 80ºC.

The HDU filter will extend the operational life time of the gearbox by continuously keeping the particle and water contamination level low.
The BG filter insert will even adsorb oxidation residue from the oil which will increase reliability of system valves.
