the MDFC1868KF16 Micro Duty Filter Cartridge fits the MDU9758KU06 Unit

• Height: 110mm
• Diameter: 60mm
• Weight: 0.20k
• Water Retention: 110ml

Long fibre cellulose with single core, nylon covering and brass fastening.

Even in small systems, contamination can quickly lead to increased wear, reduced efficiency, and premature failure. Fine particles and moisture degrade oil performance, reducing protection and increasing maintenance costs.

The MDFC1858KF06 ensures your system maintains clean, conditioned oil—helping extend oil life, protect components, and reduce downtime.

🔹 Where It’s Used

Designed for use within KLEENOIL MDU systems, this cartridge is ideal for:

• Small engines and lubrication systems
• Compact hydraulic systems
• Small gearboxes and transmissions
• Portable and mobile equipment
• Diesel fuel applications

Its ultra-compact design makes it perfect for tight installation spaces and micro-duty applications.

🔹 How It Works

The cartridge uses cellulose depth filtration technology, delivering superior performance compared to conventional filters.

• Oil enters through the central core
• It is forced through multiple layers of cellulose media
• Contaminants are trapped throughout the structure
• Water is absorbed and retained within the fibres
• Clean oil exits and returns to the system

This process ensures high-efficiency filtration and excellent dirt-holding capacity, even in demanding conditions.

🔹 Key Benefits

• Removes particles down to 3 micron
• High-efficiency filtration (β10 ≥ 1170 / 99.9%)
• Removes up to 99.8% water
• Ultra-compact design for confined spaces
• Low initial pressure drop (<0.2 bar)
• Cost-effective and easy to replace

🔹 Performance & Construction

Designed for both performance and sustainability:

• Filter Media: Long-fibre cellulose (biodegradable core)
• Outer Wrap: Polyester support layer
• Water Capacity: Approx. 110ml per cartridge
• Flow Capability: Up to 250 LPH
• Low Pressure Drop: <0.2 bar (clean filter)

This ensures efficient filtration while maintaining stable system performance.

🔹 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
   the micro has a spin on/spin off lid - unfasten it - it can be tight.
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 brass ring.
   Carefully turn the bag over the filter and seal it to contain oil residue for clean handling.
4. Install the new filter
   Insert the new cartridge with the brass ring facing upwards, pushing it fully into position.
5. Refit and secure
   Replace the lid to ensure a secure seal - no need to overtighten.
6. 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.
7. Dispose responsibly
   Dispose of the used cartridge in accordance with local regulations for oil-contaminated waste.
