2600R010BN4HC HYDAC Return Filter Element 10μm BN4HC 20bar

Product Overview

The 2600R010BN4HC (including variants such as /-B2 and /B4-KE50) is a HYDAC 2600R series return-line filter element featuring Betamicron® BN4HC 4th-generation glass-fiber media with an absolute filtration rating of 10 μm. Engineered for high-flow return lines, it offers high dirt-holding capacity, low initial differential pressure and stable beta ratios. Fully interchangeable with original HYDAC elements, it installs directly into existing housings without modifications. Every element is validated to ISO standards and undergoes 100% simulated operating condition testing, making it ideal for power plant hydraulic/lubrication systems and wind turbine gearboxes where reliable removal of metal particles and mechanical contaminants is critical to maintaining oil cleanliness and extending equipment life.

Key Technical Advantages

• Betamicron® 4th-generation media: Optimized multi-layer glass-fiber construction improves particle separation efficiency, dirt-holding capacity and beta stability while reducing Δp/Q characteristics, extending both element and fluid service life.
• High-flow return-line design: Specifically engineered for 2600-size return housings. Outside-to-inside flow direction enhances fatigue resistance and structural stability for continuous high-flow operation in power plants.
• Full interchangeability with special options: Exact dimensional and interface match to original HYDAC units. Variants such as /B4-KE50 provide pre-filtration or specific bypass settings to meet stringent power plant and wind turbine gearbox requirements.
• Rigorous quality and zinc-free construction: Validated to multiple ISO standards. Zinc-free design prevents soap formation; plastic supports and end caps improve conductivity and environmental performance for long-term reliability.

Application Areas

Power plant hydraulic and lubrication systems, wind turbine gearboxes, large construction machinery, metallurgical equipment, marine hydraulic systems, test stands, and industrial hydraulic power units requiring high-flow return-line filtration. Especially suitable for OEM and retrofit projects demanding high cleanliness levels and continuous operational reliability.

Expert Maintenance Tips

Depressurize the system and thoroughly clean the 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 indicators or contamination monitoring; do not exceed recommended pressure drop. Use appropriate-rated elements for initial flushing of new or overhauled systems. Regularly check bypass function and seal condition. Always use compatible fluid and maintain temperature and viscosity within recommended ranges to maximize element life and filtration efficiency.
