Hydac Filter | 0240D020ON | 0330D020ON | 0330D010BN3HC | 0240D020BN4HC | High Pressure Element

D-Series Industrial High-Pressure Filter Elements (0240D / 0330D Replacement)

Product Overview:

This series of filter elements is engineered as a premium replacement for Hydac D-series pressure line filters, serving as the ultimate defense for servo valves, proportional valves, and downstream precision components. In 2026, across high-precision injection molding machines, power plant servo systems, and heavy-duty hydraulic stations, models such as 0240D020ON and 0330D010BN3HC utilize superior micron-level technology to intercept wear particles, ensuring fluid integrity stays within ideal ISO 4406 standards.

Featured Model Range:

• 0240D Series: 0240D020ON, 0240D020BN4HC

• 0330D Series: 0330D020ON, 0330D010BN3HC

Key Technical Advantages:

• ON/BN3HC/BN4HC Media Technology: Features next-generation gradient-structured composite inorganic glass fiber. The 010/020 models provide absolute ratings of $10\mu\text{m}$ and $20\mu\text{m}$ respectively, with a beta ratio of $\beta_x(c) \ge 1000$, capturing ultrafine particles while maintaining low pressure drop.

• High-Collapse Structural Design: Optimized for pressure line conditions with reinforced galvanized inner cores. The structural integrity remains secure even during pressure surges, high-viscosity cold starts, or when the element is near saturation, preventing contamination from media collapse.

• Superior Dirt Holding Capacity (DHC): Scientifically optimized pleat density maximizes the effective filtration area, accommodating massive amounts of metallic debris and oxidative products to extend service intervals in intensive 2026 operations.

• $100\%$ Physical Interchangeability: Manufactured strictly to industrial dimensional tolerances with high-grade NBR seals, guaranteeing a $100\%$ leak-proof fit with original housings and eliminating bypass leakage.

• Energy-Efficient Design: Hydrodynamically optimized support layers reduce flow resistance, thereby minimizing energy loss within the hydraulic circuit.

Detailed Specifications:

• Filtration Ratings: $10\mu\text{m}$ (BN3HC grades) / $20\mu\text{m}$ (ON/BN4HC grades).

• Filter Media: High-performance composite Microglass.

• Collapse Rating: $20 \text{ bar}$ up to $210 \text{ bar}$ (depending on sub-model).

• Seal Material: Nitrile (NBR) [Viton/FKM optional].

• Compatible Mediums: Mineral oils, synthetic lubricants, and hydraulic fluids.
