The HF4P1SD4RBB3C10 filter assembly is produced by Vickers as part of the Vickers Hydraulic Accessories series and is fitted into hydraulic automation circuits to remove solid contaminants. The assembly length is 447 mm (17.6 in), defining the clearance required for service access. A ductile-iron head resists pressure cycling, while a carbon-steel bowl secures the element and retains fluid under load. Its C-Pak low-collapse element construction simplifies replacement, and the element withstands a collapse pressure of 10 bar (150 psi) to prevent media failure during flow reversal. The housing endures a maximum operating pressure of 345 bar (5000 psi) and carries a fatigue rating of 240 bar (3500 psi) for long life in pulsating systems. Continuous flow capacity is 189 L/min (50 USgpm), allowing use on medium-sized power units without excessive pressure drop.
The assembly includes a bypass valve that cracks at 2.9 bar (43 psi) to keep oil moving when the element is blocked, and a condition indicator set at 2 bar (30 psi) signals replacement before bypass occurs. The indicator is wired through a Brad Harrison connector for straightforward integration with monitoring circuits. When serviced on schedule, the unit maintains ISO 20/18/15 cleanliness to protect sensitive valves and actuators. A 1.875-12 UN SAE-24 threaded port accepts 1-1/2 in tubing for direct connection to standard line sizes. Dry weight is 28.8 kg (63.4 lb), so mounting brackets must support the static load. Buna-N seals are fitted for compatibility with mineral oils, and operating temperature spans 6 to +121 °C, permitting reliable service in both mobile and industrial environments.
