RFA-40X10L-Y – Reliable Hydraulic Filtration, Simplified Service, Smarter Protection

Product Update Announcement: RFA-40X10L-Y Oil Return Filter – Enhanced Reliability,

 Simplified Maintenance, Expanded Application Coverage

We are pleased to announce a comprehensive product update for our widely

 trusted RFA-40X10L-Y oil return filter. Since its market introduction, 

the RFA-40X10L-Y has been recognized for its robust performance in hydraulic system 

oil return fine filtration. Based on extensive field feedback from diverse industries, 

we have refined its design, expanded its media compatibility, and enhanced its

 operational intelligence – ensuring the new-generation RFA-40X10L-Y continues 

to set the benchmark for reliability, serviceability, and system protection.

1. Streamlined Installation for Compact System Layout

The updated RFA-40X10L-Y retains its proven tank-top mounting design, 

with the filter head positioned outside the tank and the return cylinder fully immersed in the oil.

 This configuration eliminates complex external piping, significantly reducing installation

 space requirements. We have further optimized the flange and threaded connection

 interfaces to accommodate a wider range of hydraulic system layouts, 

making the RFA-40X10L-Y even easier to integrate into both new builds and retrofit projects.

2. Intelligent Contamination Monitoring with Enhanced Safety Redundancy

System reliability is paramount in hydraulic applications. The RFA-40X10L-Y now features 

an upgraded filter element contamination transmitter with improved sensitivity and

 response time. When the inlet pressure rises to 0.35MPa – due to element clogging,

 low oil temperature, or flow pulsation – the signalling device provides a clear, timely alert. 

This allows operators to schedule maintenance proactively. Should immediate machine 

shutdown be impractical, the integrated bypass valve (opening pressure: 0.4MPa) 

automatically engages to protect both the filter element and the entire hydraulic 

circuit from damage. This dual-layer protection ensures uninterrupted production

 while safeguarding critical components.

3. Tool-Friendly, Straight-Back Design for Unmatched Service Convenience

Maintenance has been made simpler than ever. The straight-back oil return architecture 

allows operators to replace the filter element or add oil to the tank with minimal

 effort – simply unscrew the filter cover (cleaning cover). No specialized tools or 

lengthy disassembly procedures are required. Additionally, the filter head is

 equipped with two M18×1.5 oil ports, offering flexible options for installing a

 transmitter on either side or returning a small oil flow to the tank for continuous filtration.

 This thoughtful design reduces downtime and labor costs, keeping your hydraulic

 system online longer.

4. Flow Diffuser for Bubble-Free Oil Return

Air entrainment in hydraulic fluid can lead to pump cavitation, system noise, 

and reduced component life. The RFA-40X10L-Y incorporates a specially designed 

flow diffuser at the bottom of the oil return cylinder. This diffuser ensures smooth, 

low-turbulence return flow into the tank, effectively minimizing bubble formation

 and preventing air from re-entering the system. The result is quieter operation, 

improved fluid stability, and extended pump and valve service life.

5. Broad Media Compatibility for Diverse Applications

To meet the evolving demands of modern industry, the updated RFA-40X10L-Y now 

supports an expanded range of working media, including:

· General hydraulic oil

· Phosphate ester hydraulic oil (for fire-resistant applications)

· Emulsions

· Water-hexanediol fluid systems

With a flow capacity ranging from 25 to 1000 L/min, filtration precision from 1 to 30μm,

 and a standard working pressure of 1.6MPa, this single filter platform can now serve an 

even broader spectrum of processes.

6. Expanded Application Fields

The versatility of the RFA-40X10L-Y makes it a preferred choice across multiple sectors:

Industry Typical Applications

Electronics & Pharmaceuticals Pre-treatment and final filtration of reverse osmosis water, 

deionized water, cleaning solutions, and glucose solutions

Thermal & Nuclear Power Oil purification in gas turbine lubrication systems, speed control

 systems, and bypass control systems

Railway & Power Generation Lubricating oil and fuel oil filtration for diesel engines and

 generators

Automotive & Construction Machinery Engine air/oil/fuel filters; hydraulic and diesel 

filters for construction equipment, marine vessels, and heavy trucks
