This washable inline filter uses stainless steel wire mesh, operates at 280 bar, features G¾” ports, and supports repeated cleaning for cost‑effective industrial use.


The MDF W series inline filter assembly features a stainless steel wire mesh filter element that can be cleaned and reused multiple times, significantly reducing operating costs and environmental waste. It is specially designed for applications where frequent filter replacement is impractical or costly, such as heavy machinery, hydraulic test benches, and lubrication systems.
Despite its reusable design, the unit maintains full pressure resistance up to 280 bar and provides reliable protection against coarse and medium particles. The robust wire mesh structure resists collapse and deformation even under high differential pressure, ensuring stable performance throughout multiple cleaning cycles.

The heavy‑duty housing construction ensures stable operation under vibration, shock, and high pressure. The inline mounting style saves installation space and simplifies pipeline layout. The standardized port design ensures wide compatibility with common hydraulic piping systems, reducing installation and conversion costs.
The wire mesh element provides high mechanical stability and excellent flow characteristics. It can withstand backflushing, ultrasonic cleaning, and solvent washing without losing shape or filtration efficiency. This makes the MDF W series ideal for users seeking a durable, low‑cost‑of‑ownership filtration solution.
This filter assembly is widely used in hydraulic systems, lubrication systems, gearboxes, compressor lubrication circuits, and industrial fluid handling systems. It is especially suitable for conditions where high solid particle loads are present and reusable filtration is preferred.
