🔹 Product Overview

The KLEENOIL KF65 Replacement Cartridge is a high-efficiency filter element designed for advanced oil and fuel conditioning in demanding applications. Engineered for use within KLEENOIL KU65 bypass filtration systems, it delivers exceptional removal of fine particulates and water from lubricating, hydraulic, and diesel fuel oils.

With a larger capacity design, the KF65 is ideal for systems requiring increased water absorption and extended filtration performance.

🔹 Why You Need This Cartridge

Contamination—both particulate and moisture—is the primary cause of oil degradation and system wear. In higher volume or fuel-based systems, effective water removal becomes even more critical.

The KF65 cartridge is specifically designed to handle these demands, maintaining oil and fuel in optimal condition while extending service intervals and protecting equipment.

🔹 Where It’s Used

Designed for use within KLEENOIL KU65 systems, the KF65 is suitable for:

• Diesel fuel filtration and polishing systems
• Hydraulic systems and lubrication circuits
• Engines and industrial equipment
• Fuel storage and transfer applications
• Mobile and fixed plant machinery

Its higher capacity makes it particularly effective in fuel cleaning and larger system applications.

🔹 How It Works

The KF65 utilises cellulose depth filtration technology, delivering superior performance compared to conventional surface filters.

• Contaminated oil or fuel enters through the core
• Fluid is forced through multiple layers of filtration media
• Fine particles are captured throughout the structure
• Water is absorbed and retained within the cellulose fibres
• Clean fluid exits and returns to the system

This process ensures consistent high-efficiency filtration and excellent contaminant retention, even under demanding conditions.

🔹 Key Benefits

• Removes particles down to 3 micron
• High-efficiency filtration (β10 ≥ 1170 / 99.9%)
• Removes up to 99.8% water
• High water absorption capacity (approx. 700ml per cartridge)
• Suitable for oil, hydraulic, and diesel fuel applications
• Extended service life and reduced maintenance frequency

🔹 Performance & Construction

Built for durability and high-capacity performance:

• Filter Media: Long-fibre cellulose (biodegradable core)
• Outer Wrap: Polyester support layer
• Water Capacity: Approx. 700ml per cartridge
• Flow Capability: Up to 250 LPH
• Operating Range: -20°C to +100°C
• Low Pressure Drop: <0.2 bar (clean filter)

This ensures stable operation and effective filtration across a wide range of environments.

🔹 Technical Specifications

• Height: 100 mm
• Diameter: 180 mm
• Weight: Approx. 0.75 kg
• Micron Rating: 3 micron
• Efficiency: β10 = 1170 (99.9%)

🔹 Filter Replacement (Quick & Clean Process)

Changing your KLEENOIL cartridge is a simple and clean process, designed for minimal mess and quick servicing.

1. Remove the lid
   Undo the retaining bolts and keep them safe for refitting.
2. Prepare the new cartridge
   Unpack the new filter and keep the protective bag aside—you’ll use this for removal of the old element.
3. Remove the used filter (cleanly)
   Place the bag over the filter housing, reach in, and lift the used cartridge out using the web handles.
   Carefully turn the bag over the filter and seal it to contain oil residue for clean handling.
4. Check and clean the lid
   Wipe the lid with a clean cloth and remove the old lid seal.
   Replace with the new seal, ensuring the sealing surface is clean and free from debris.
5. Install the new filter
   Insert the new cartridge with the brass ring facing upwards, pushing it fully into position.
6. Refit and secure
   Replace the lid and tighten the bolts evenly to ensure a secure seal.
7. Run and check
   Start the system and allow it to run for a few minutes.
   Check the lid area to confirm there are no leaks and the seal is effective.
8. Dispose responsibly
   Dispose of the used cartridge in accordance with local regulations for oil-contaminated waste.
