R-Series Industrial High-Flow Return Hydraulic Filter Elements

Product Overview:

This series of filter elements is specifically engineered for Hydac R-series return line filter housings, serving as a critical component for maintaining hydraulic fluid integrity. In 2026, across high-efficiency power units, injection molding machinery, and heavy-duty machine tools, these models utilize patented ON (Betamicron®) technology to intercept metallic wear and oxidative contaminants, preventing secondary pump wear caused by reservoir contamination.

Featured Model Range:

• 0240R Series: 0240R003ON, 0240R005ON, 0240R010ON

• 0330R Series: 0330R003ON, 0330R005ON

• Large Size Series: 0500R005ON, 0660R005ON

Key Technical Advantages:

• ON (Betamicron®) Grade Media: Employs next-generation gradient composite media. The 003ON and 005ON provide absolute ratings of $3\mu\text{m}$ and $5\mu\text{m}$ respectively, with a beta ratio of $\beta_x(c) \ge 1000$.

• Low Pressure Drop & High Flow: Optimized pleat geometry tailored for return line characteristics maximizes effective surface area, maintaining low initial pressure drop during cold starts or flow surges.

• Superior Dirt Holding Capacity (DHC): Compared to conventional media, the ON series offers deeper retention space, accommodating far more particles and significantly extending maintenance intervals.

• Reinforced Inner Core Support: Features thickened galvanized anti-corrosion support tubes, ensuring structural integrity under return flow pulses and preventing media collapse.

• $100\%$ Physical Interchangeability: Manufactured to strict industrial tolerances with high-grade NBR seals, guaranteeing a “zero-leakage” fit with original filter housings.
