Slurry De-Iron Filter XN-FTM-5L
SKU: XN-FTM-5L
Slurry De-Iron Filter XN-FTM-5L is a combined magnetic de-iron and vacuum filtration unit for the optimization step between slurry mixing and electrode coating in lithium-ion battery manufacturing. The unit removes both ferromagnetic contamination (via removable permanent magnets at 8,000–10,000 Gauss) and oversize hard particles (via a vacuum-driven filtration screen) in a single batch process.
XN-FTM-5L handles 5 L per batch, accepts mesh sizes up to 1000-mesh (80–120 mesh recommended for typical lithium-ion electrode slurries), and is suitable for slurries up to 20,000 cP viscosity and 80% solid content. The all-stainless-steel build supports thorough cleaning between cathode and anode runs.

Name: Slurry De-Iron Filter XN-FTM-5L
Equipment Type: Combined Magnetic De-Iron and Vacuum Filtration Unit
Product code: XN-FTM-5L
Brand: Xnergy
Product Introduction:
Slurry De-Iron Filter XN-FTM-5L is a combined magnetic separation and vacuum filtration unit designed for slurry optimization between mixing and electrode coating in lithium-ion battery manufacturing. Removable high-strength permanent magnets capture ferromagnetic contamination (Fe, Ni, magnetic alloys) from cathode and anode slurries, while a vacuum-driven filtration screen below removes oversize hard particles in the same batch. The all-stainless-steel construction supports thorough cleaning between cathode and anode runs, and the 5 L per-batch capacity is sized for pilot and small-production electrode workflows.
Working Principle:
Slurry is poured into the upper chamber, where permanent magnets capture ferromagnetic particles. Vacuum then draws the slurry through a fine filtration screen into the lower chamber, removing oversize hard particles. Once filtration is complete, a discharge valve is opened to transfer the optimized slurry to the next process step.
Key Features:
Dual-action slurry treatment — magnetic de-iron + vacuum filtration in one batch
Removable permanent magnets at 8,000–10,000 Gauss for efficient capture of ferromagnetic contamination
Easy magnet removal for cleaning and inspection
All-stainless-steel construction for corrosion resistance and cleanability
Filtration mesh up to and including 1000-mesh (80–120 mesh recommended for lithium-ion electrode slurries)
Suitable for slurries up to 20,000 cP viscosity and 80% solid content
5 L per-batch capacity sized for pilot and small-production electrode preparation
Discharge valve for controlled slurry transfer to downstream process

Application Areas:
XN-FTM-5L is suitable for:
Optimizing lithium-ion battery cathode and anode slurries between mixing and coating
Removing ferromagnetic contamination (Fe, Ni, magnetic alloys) that would otherwise cause internal short-circuit risk in finished cells
Removing oversize hard particles that would otherwise cause coating streaks or pinholes
Pilot and small-production electrode preparation workflows where slurry consistency and coating yield matter
Maintenance:
Clean the equipment regularly with a soft cloth lightly moistened with alcohol
Lubricate moving parts periodically to ensure smooth operation
If the equipment is not used for an extended period, clean the moving surfaces and apply a protective anti-rust coating
Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening
Remove and clean the permanent magnets between batches to maintain de-iron efficiency
Safety Notes:
Do not place hands or other body parts near moving components or work-zone areas during operation
Operation should be performed by a single trained operator to avoid accidental injury
Disassembly should only be performed by qualified technicians
Handle the strong permanent magnets with care during cleaning — keep clear of magnetic-sensitive electronics, pacemakers, and tools

Note: Specifications listed above are typical and for reference only. Actual filtration and de-iron performance depend on slurry viscosity, solid content, contamination level, and operating conditions. XN-FTM-5L is the larger version of Xnergy’s de-iron filter line and is the right match when single-batch slurry volumes exceed 2 L — typical for pilot lines feeding slot-die coating from XN-PVM-5L or larger planetary mixers, where matching the de-iron throughput to the mixer batch size keeps the workflow continuous. For smaller R&D batches up to 2 L, the more compact XN-FTM-2L offers the same magnetic strength and filtration accuracy in a lighter footprint. When magnetic separation is not required, the simpler vacuum-only XN-FT-2L slurry filter is a lower-cost alternative. The de-ironed, filtered slurry then feeds the Slot-Die Coating System XN-SDC for precision continuous coating. For cathode materials where de-iron treatment is most critical — particularly NCM, NCA, LFP, and LMFP — see our Cathode Materials catalog.
