The SDU H350 UW is an offline filter designed to operate in a sub sea environment (suitable for use on ROV's, TMS's etc). Developed from our popular SDU H350, the UW variant has stainless steel fittings & brackets, a black-anodised filter housing (to provide corrosion protection and eliminate flare from lighting) and a bleed valve to purge air from the hydraulic system following a filter change.

The SDU H350 UW is permanently installed using the bracket supplied. A pressurised feed (up to 350 Bar) is taken from a hydraulic circuit, and a return line (to tank) completes the bypass loop. A flow compensating, pressure reducing valve arrangement reduces the pressure in the filter housing to 4 Bar, and restricts the flow rate to 2 l/min.
