High-Performance D & DN Series High-Pressure Filter Elements

Product Overview:

This series of filter elements is specifically engineered for Hydac-spec high-pressure line filters. In 2026, across high-precision machine tools, steel mill servo systems, and wind power units, these elements are essential for maintaining fluid cleanliness according to ISO 4406 standards. Whether utilizing ON (Betamicron®) media for ultra-fine filtration or BH4HC high-collapse models for non-bypass circuits, they provide superior system protection.

Featured Model Matrix:

• 0280D003ON / 0035D010ON: High-efficiency Microglass, $3\mu\text{m}$ and $10\mu\text{m}$ absolute ratings.

• 0250DN010BN4HC: DN specification 4th-gen high-performance media.

• 0240D003BH4HC: Ultra-precision $3\mu\text{m}$ rating with $210 \text{ bar}$ high-collapse resistance.

Key Technical Advantages:

• ON / BN4HC Grade Media: Features multi-layer gradient inorganic glass fiber with a beta ratio of $\beta_x(c) \ge 1000$. Hydrodynamically optimized for $3\mu\text{m}$ and $10\mu\text{m}$ ratings to significantly reduce initial pressure drop.

• BH4HC Extreme Collapse Resistance: The 0240D003BH4HC model is designed for high-pressure circuits without bypass valves, featuring a reinforced core that sustains up to $210 \text{ bar}$ differential pressure, protecting downstream proportional valves.

• Superior Dirt Holding Capacity (DHC): Scientifically optimized pleat geometry maximizes the effective filtration area, offering longer service intervals and lower maintenance costs during intensive 2026 production cycles.

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

• Energy-Efficient Operation: Optimized support layers reduce flow resistance, contributing to lower total energy consumption in the hydraulic system.

Detailed Specifications:

• Filtration Ratings: $3\mu\text{m}$ (0280D/0240D) / $10\mu\text{m}$ (0250DN/0035D).

• Collapse Rating: $20 \text{ bar}$ (Standard) / $210 \text{ bar}$ (High-Pressure BH4HC).

• Seal Material: Nitrile (NBR) standard.

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