Product Overview

Admiral's duplex lube oil filters provide uninterrupted flow during fluid transfer and cartridge changeout. Filtration of lube oil at flows up to 1500 GPM are standard. Higher flows are available, with system pressures up to 500 p.s. i.

Admiral's duplex lube oil filters are installed on hundreds of naval and merchant marine vessels worldwide, including frigates, destroyers and submarines, e.g. AD, AOE, LSD, AO, FF, AS, DDG, SSN, LHA, MCM,FFG, and DD class, US Navy ships, plus those of foreign navies.

Product Description

Two cylindrical housings are connected via inlet and outlet valves. The valves are linked by a common gear box with a hand wheel that allows selection of a clean housing without interruption of the oil flow. Oil enters the top of the housing, and particulates are trapped within the elements as the oil passes through. When a predetermined differential pressure is reached, changeover to a clean housing is accomplished, automatically or manually. The cover hold-down bolts and vent valve associated with the out of service housing become exposed and this allows the dirty filter elements to be cleaned or replaced without interruption of flow.
