In the demanding world of marine and industrial engineering, the longevity of an engine is only as good as the cleanliness of its oil. As a leading manufacturer of Full Flow Filter Elements for Moatti systems, we understand that these components are the heart of an engine’s lubrication and fuel systems.
What is a Moatti Full Flow Filter Element?

A Moatti Full Flow Filter Element is a specialized, disc-type filtration component designed for automatic backflushing filter systems. Unlike traditional “spin-on” cellulose filters that require frequent disposal, Moatti elements are engineered for continuous operation and long-term durability.
They are primarily used to treat:
- Lubricating Oil: Protecting four-stroke and two-stroke engines from metallic wear and carbon deposits.
- Fuel Oil (HFO, MDO, VLSFO): Removing “cat fines” (catalytic fines) and impurities that can cause catastrophic engine failure.
Key Technical Features
As manufacturers, we build our elements to meet or exceed OEM specifications, ensuring seamless integration into existing housing units (such as the 150, 152, 240, and 350 series).
| Feature | Specification / Benefit |
| Material | High-grade stainless steel mesh with robust aluminum or stainless armatures. |
| Filtration Type | Surface Filtration: Contaminants are trapped on the outer mesh, allowing for efficient backflushing. |
| Micron Ratings | Available from 10 µm (fine fuel filtration) up to 100+ µm for heavy lube oil. |
| Design | Disc-stack configuration creates multiple independent filtering columns. |
| Durability | No paper components; resistant to high pressure and chemical degradation. |
How the Full Flow System Works

The “Full Flow” designation means that 100% of the oil passing to the engine is filtered. The Moatti system is unique because it uses the pressure of the filtered oil itself to drive a hydraulic motor, requiring no external power source.
- Filtration: Oil enters the filter housing and passes through the stainless steel mesh of the disc stack from the outside in.
- Continuous Backflushing: A rotating distributor inside the stack opens small sectors of the filter to a lower-pressure discharge line.
- Self-Cleaning: This pressure differential forces a small portion of clean oil back through the mesh (from inside to outside), blowing off trapped particles.
- Zero Downtime: Because only one small sector is backflushed at a time, the engine receives a constant, uninterrupted flow of clean oil.
Why Choose Our Moatti-Compatible Filter Elements?

Switching to high-quality elements from a dedicated manufacturer offers several strategic advantages for fleet managers and plant operators:
1. Elimination of Disposable Cartridges
Traditional filters generate massive amounts of waste and require engine shutdowns or manual bypasses for replacement. Our elements are permanent and self-cleaning, drastically reducing your environmental footprint and OPEX.
2. Constant Pressure Drop
Because the filter is continuously cleaned, there is no “clogging curve.” The pressure drop remains stable, ensuring consistent lubrication even in heavy-duty cycles.
3. Superior Protection Against Cat Fines
For vessels running on VLSFO (Very Low Sulphur Fuel Oil), our 10 µm elements are the gold standard for removing abrasive catalytic fines that can score cylinders and damage fuel pumps.
4. Precision Engineering
Our manufacturing process ensures that the mesh tension is perfect. This prevents “mesh fluttering,” which is the leading cause of premature wire fatigue and element failure in lower-quality alternatives.
Maintenance & Longevity
While Moatti elements are designed for longevity, “permanent” does not mean “maintenance-free.” To ensure peak performance:
- 12,000-Hour Inspection: We recommend a full overhaul and ultrasonic cleaning of the disc stacks every 12,000 operating hours.
- Monitor Differential Pressure: A sudden spike in pressure ($\Delta P$) usually indicates a failure in the hydraulic motor or distributor, rather than the elements themselves.
- Use High-Quality Spares: Using sub-standard mesh can lead to “mesh migration” or tearing, which allows unfiltered oil to reach the engine.
