Hydac Replacement Filter | 0660D010BH4HC | 2600R004ON/-B4-KE50 | Industrial Oil Filter Element

Industrial High-Pressure & Return Hydraulic Filter Elements

Product Overview:

This series of filter elements is engineered for Hydac industrial filter housings, covering essential specifications for both pressure lines (D-Series) and high-flow return lines (R-Series). In 2026, within high-precision hydraulic power units, steel mill rolling equipment, and power plant lubrication systems, these elements utilize patented Betamicron (BH/ON) glass fiber technology to maintain fluid integrity to ISO 4406 standards.

Featured models: 0660D010BH4HC (High Pressure) and 2600R004ON/B4-KE50 (Return).

Key Technical Advantages:

• BH4HC Extreme Collapse Resistance: The 0660D010BH4HC is designed for high-pressure systems without bypass valves. Featuring a reinforced hexagonal inner core, it sustains a collapse pressure of $210 \text{ bar}$, preventing structural failure even under extreme differential pressure spikes.

• ON (Betamicron) High-Flow Technology: Model 2600R004ON employs multi-layer gradient-structured inorganic glass fiber with outstanding $\beta_4(c) \ge 1000$ efficiency. Optimized for return flow, it significantly minimizes operating pressure drop.

• Precision Sealing & KE Structure: Manufactured strictly to industrial dimensional standards with high-grade NBR seals, ensuring a $100\%$ leak-proof fit with the filter head.

• Superior Dirt Holding Capacity: Scientifically optimized pleat distribution maximizes the effective filtration area, providing over $30\%$ higher dirt-holding capacity than conventional elements, thus extending service intervals.

• Broad Media Compatibility: Suitable for mineral oils, cutting fluids, water-glycols, and synthetic lubricants.
