0160DN006BN4HC Hydraulic Pressure Oil Filter

Product introduction

Hydac Replacement D Series oil filter cartridges are high-performance interchangeable filtration elements engineered to directly substitute Hydac D‑series pressure/return line filter elements (e.g., 0030D, 0060D, 0160D, 0330D series). Designed for hydraulic oil, lubricating oil, turbine oil, gear oil, and other industrial hydrocarbon fluids, they replicate the dimensional, structural, and performance specifications of original Hydac cartridges for seamless drop‑in replacement. These filters efficiently capture solid contaminants including metal wear debris, sludge, rust, scale, and colloidal impurities, maintaining fluid cleanliness per ISO 4406 and NAS standards. By protecting precision components such as pumps, servo valves, bearings, and gears, they minimize equipment wear, reduce unplanned downtime, extend oil service life, and ensure stable operation of hydraulic and lubrication systems across heavy‑duty industrial environments.

Filtration accuracy

This series offers a full spectrum of absolute filtration ratings with βₓ ≥ 1000 and filtration efficiency up to 99.9% at the rated particle size. Standard precision grades cover 1 μm, 3 μm, 5 μm, 10 μm, 20 μm, and 40 μm, matching Hydac’s original performance metrics. High‑efficiency microglass media delivers consistent particle removal across variable flow rates, pressures, and oil viscosities, effectively controlling contamination levels and safeguarding sensitive hydraulic components. For ultra‑clean applications, specialized versions achieve 1 μm absolute filtration, meeting the strict cleanliness requirements of servo systems and precision machinery.

Filter media

The core filtration material is multi‑layer gradient‑density borosilicate microglass media, produced via an adhesive‑free hot‑melt lamination process to eliminate binder shedding and secondary contamination. The gradient pore structure provides coarse pre‑filtration upstream and fine precision filtration downstream, balancing high dirt‑holding capacity with low initial pressure drop. The media is reinforced with a stainless steel or galvanized steel inner support tube and external protective mesh to resist collapse and deformation under high pressure (up to 42 MPa) and flow shocks. End caps are constructed from steel/aluminum alloy, paired with NBR or FKM (FPM) O‑ring seals for zero‑bypass performance, excellent oil resistance, and compatibility with mineral and synthetic fluidsHYDAC.

Replacement cycle

Under normal operating conditions, the service life ranges from 3 to 12 months, aligned with original Hydac D‑series guidelines. In standard hydraulic/lubrication systems with moderate contamination, the typical replacement interval is 6–12 months. For harsh environments (mining, metallurgy, construction machinery) or high‑wear systems, the cycle shortens to 3–6 months to sustain optimal filtration. In clean, controlled applications (precision manufacturing, power generation), life can extend to 9–12 months with regular monitoring. Replacement is mandatory when differential pressure reaches 0.35–0.4 MPa to prevent bypass, system blockage, or component damage.

Features

1. Direct Hydac interchangeability: Matches original dimensions, connections, and performance for hassle‑free replacement with no system modifications required.

2. High‑efficiency filtration: βₓ ≥ 1000 absolute rating and up to 99.9% efficiency for reliable contaminant removal.

3. Large dirt‑holding capacity: Gradient microglass media maximizes contaminant retention and extends service intervals.

4. Low pressure drop design: Optimized pleating and media structure minimize flow resistance and energy consumption.

5. Robust pressure resistance: Reinforced steel support withstands operating pressures up to 42 MPa, suitable for high‑pressure hydraulic circuits.

6. Reliable zero‑bypass sealing: NBR/FKM gaskets ensure leak‑free performance in high‑temperature and high‑vibration conditions.

7. Wide fluid compatibility: Media and seals compatible with mineral oils, synthetic oils, phosphate esters, and most industrial lubricants.

8. Compliance with global standards: Manufactured to ISO 16889 and Hydac original specifications for consistent quality and performance.

Application areas

Hydac Replacement D Series cartridges are widely used in systems requiring direct Hydac compatibility, including:

• Hydraulic systems: Construction machinery, machine tools, injection molding, die‑casting, marine hydraulics, and mobile equipment.

• Lubrication systems: Turbines, compressors, gearboxes, reducers, and large rotating machinery in power plants, steel mills, and cement facilities.

• Metallurgy & mining: Rolling mills, crushers, excavators, and continuous casting equipment hydraulic/lubrication circuits.

• Power generation: Thermal power plants, generator sets, turbine lube systems, and transformer oil purification.

• Petrochemical industry: Refinery process fluid filtration, pump lubrication, and compressor oil systems.

• Marine & offshore: Ship engine lubrication, deck machinery hydraulics, and offshore platform fluid systems.

• Industrial maintenance: Offline filtration carts, oil recycling units, and fluid conditioning systems.

Conclusions

Hydac Replacement D Series oil filter cartridges deliver a cost‑effective, high‑performance alternative to original Hydac D‑series elements, combining identical form, fit, and function with superior value. Engineered for direct interchangeability, they maintain the same filtration efficiency, pressure resistance, and service life as OEM parts while reducing procurement costs. With advanced gradient microglass media, robust structural design, and reliable sealing, these filters effectively control fluid contamination, protect critical components, and extend equipment and oil life across diverse industrial applications. For operators seeking reliable Hydac replacement solutions without compromising performance, this series provides a dependable, standards‑compliant choice for hydraulic and lubrication system purification.
