The HV6R1MT4LNB8C10 filter is produced by Vickers within the Vickers Hydraulic Accessories series. The unit serves as a return-line element that removes contaminants as oil returns to the reservoir in automated hydraulic circuits. It fits directly inside the tank, following the in-tank mounting style, which simplifies plumbing and reduces external pipework. An overall assembly length of 1045 mm (41.1 in) allows the housing to reach the fluid level while keeping the cover accessible for service. The inlet accepts a 4 in SAE Code 61 flange so that high-volume systems can connect without adapters. With a rated flow of 1700 L/min (450 gpm), the filter accommodates large mobile or industrial power units, and the aluminum housing withstands continuous operating pressure up to 25 bar (360 psi) without excessive weight. The dry mass remains 23 kg (50 lb), permitting single-person installation during maintenance cycles.
The filtration element achieves a Beta ratio of 1000 per ISO 16889, meaning it captures 99.9 % of particles at its micron rating to reach a system cleanliness target of ISO 20/18/15. A bypass valve set to 3 bar (43 psi) protects the element by diverting flow when differential pressure rises, while a visual 2 bar clogging indicator alerts personnel to replace the cartridge before bypass occurs. The C-Pak standard construction resists deformation, and a collapse pressure rating of 10 bar (150 psi) keeps the pleats intact during cold-start surges. Buna-N seals maintain compatibility with typical petroleum oils across a temperature range of −30 to 121 °C (−22 to 250 °F), ensuring leak-free operation in mobile equipment or stationary presses.
