The MENRED WFFA.DH02 is a sediment pre-filter for first-stage filtration on residential main water lines. Its 40 μm stainless steel mesh helps intercept sand, rust particles and suspended solids in incoming municipal tap water.
The unit requires no electrical supply and has a listed filtration flow rate of 6.0 m³/h. Its reusable mesh provides a cleanable filtration element without routine disposable sediment cartridge replacement.
Positioned upstream of the equipment it is intended to protect, the WFFA.DH02 helps reduce particulate loading on downstream filters, valves and water-using appliances. Its mesh is intended for sediment filtration rather than treatment of dissolved contaminants.
A 40 μm pre-filter does not replace water softening, disinfection or a complete drinking-water treatment system. Select additional treatment according to incoming water quality and the intended use.
The stainless steel mesh can be cleaned and reused, avoiding routine replacement of disposable sediment cartridges. Reusability does not eliminate maintenance: inspect and clean the filtration element according to the product instructions.
Cleaning frequency depends on sediment loading, water consumption and operating conditions. Accumulated sediment can increase pressure loss and reduce flow. Follow the specified servicing procedure and isolate and depressurise the unit before any maintenance that requires opening it.

Actual flow and pressure loss depend on supply pressure, pipework, sediment loading and mesh condition. Confirm connection size, dimensions and the cleaning procedure before ordering.
Install the pre-filter on the incoming municipal water line, upstream of the equipment it is intended to protect. Follow the model-specific instructions for mounting orientation, flow direction and pipe connections.
The WFFA.DH02 is an option for installations requiring a reusable sediment mesh without an electrical supply. Select the model according to water source, required flow, sediment loading and maintenance arrangements.
Compare the Lunde automatic backwash pre-filter for scheduled powered cleaning, or the Lech PP cartridge pre-filter for cartridge-based filtration. Explore the full MENRED pre-filter range.
No. The WFFA.DH02 does not require an electrical supply for filtration.
The mesh helps intercept sand, rust particles and suspended solids in municipal tap water. It does not replace disinfection, water softening or treatment of dissolved contaminants.
The listed filtration flow rate is 6.0 m³/h, equivalent to 100 litres per minute. Actual flow depends on supply pressure, pipework, sediment loading and mesh condition.
Yes. The mesh requires inspection and cleaning according to water conditions and the product instructions. It avoids routine disposable cartridge replacement but is not maintenance-free.
The published specification identifies municipal tap water as the application for WFFA.DH02. Confirm suitability with MENRED before selecting it for well water or another water source.
Confirm the water source, required flow, operating pressure, water temperature, connection size, installation space and cleaning requirements.
