The HF4P1BD6UBV3C05 filter assembly is produced by Vickers in the Vickers Hydraulic Accessories series and is applied in hydraulic automation to remove particulate contamination from pressure lines. The unit measures 447 mm (17.6 in) overall, so it fits medium power packs without excessive height. A ductile iron head withstands a continuous operating pressure of 345 bar (5000 psi), and a carbon-steel bowl contains the element during service. The pressure boundary survives cyclic loading at 240 bar (3500 psi), while a bypass valve opens at 6 bar (90 psi) to keep oil flowing if clogging occurs. The low-collapse C-Pak element tolerates 10 bar (150 psi) differential before failure, capturing debris safely. Viton-A seals resist hydraulic oil and temperature swings, preventing leakage across the entire pressure range.
The assembly handles 189 L/min (50 USgpm) so it matches common pump outputs used in industrial machinery. It filters particles to 5 µm, helping systems reach ISO cleanliness class 18/16/14 for reliable valve operation. An electrical Brad Harrison indicator activates at 4.9 bar (70 psi) differential to alert maintenance when replacement is required. Operating limits from −26 to +121 °C (−15 to +250 °F) allow outdoor or indoor use with mineral or synthetic fluids. A G1-1/2 straight-thread port conforming to ISO 228 simplifies installation with standard fittings. These specifications let the HF4P1BD6UBV3C05 maintain fluid quality and continuous flow in automated hydraulic equipment.
