1300R003ON/-V 1300R005ECON2 HYDAC Return Filter Element

Product Overview

The 1300R003ON/-V and 1300R005ECON2 are HYDAC 1300R series return-line filter elements (covering 1300R003, 1300R005, 1300R010, 1300R020, 1300R050, 1300R100, 1300R200 ratings). They feature Optimicron® (ON) or ECOmicron® (ECON2) high-performance glass-fiber media with absolute filtration ratings of 3 μm and 5 μm. Designed specifically for hydraulic system return lines, they deliver high dirt-holding capacity, low initial differential pressure and stable beta ratios. Fully interchangeable with original HYDAC elements, they install directly into existing housings without modifications. Every element is validated to ISO standards and undergoes 100% simulated operating condition testing to reliably remove metal particles, wear debris and other mechanical contaminants, maintaining high oil cleanliness and extending the service life of critical system components.

Key Technical Advantages

• Optimicron® / ECOmicron® high-performance media: Unique HELIOS pleat geometry and multi-layer glass-fiber construction optimize flow paths, delivering high separation efficiency, long service life and low differential pressure for improved energy efficiency.
• High-flow return-line design: Specifically engineered for 1300-size return housings. Outside-to-inside flow direction enhances structural stability and fatigue resistance for continuous high-load operation.
• Full interchangeability and reliable sealing: Exact dimensional and interface match to original HYDAC units. NBR/FKM seals ensure leak-free, easy installation and reduced downtime.
• Rigorous quality control: Manufactured and tested to multiple ISO standards with simulated duty-cycle verification, guaranteeing long-term reliability under vibration, temperature fluctuations and high contamination loads.

Application Areas

Construction machinery, injection molding machines, die-casting machines, metallurgical equipment, power plant hydraulic systems, marine hydraulics, machine tools, test stands, and high-flow hydraulic power units requiring return-line filtration. Especially suitable for OEM equipment and retrofit projects that demand rapid element replacement and consistent high oil cleanliness levels.

Expert Maintenance Tips

Depressurize the system and thoroughly clean the filter housing interior before replacement to prevent secondary contamination. Ensure seals are intact and correctly seated, then tighten to the specified torque. Replace according to differential pressure indicator readings or system contamination monitoring; do not exceed recommended pressure drop. Use appropriate-rated elements for initial flushing of new or overhauled systems. Regularly inspect seals and housing condition for corrosion. Always use compatible hydraulic fluid and maintain temperature and viscosity within recommended ranges to maximize element life and filtration efficiency.
