The Eaton DCF-400 Series represents a highly efficient, compact solution for continuous filtration within busy industrial processing lines. Appropriate for water-like liquids and low-volume, high-viscosity fluids, the DCF-400 eliminates standard operational overhead by replacing traditional consumable filter elements (such as bags and cartridges) with a sustainable, media-free mechanical scraping architecture.
Constructed entirely with heavy-gauge 316 Stainless Steel wetted components and structural housing configurations, this durable filter prevents fluid line blockages without interrupting product flow during cleaning intervals. Debris is pushed continuously to a concentrated bottom containment zone where it can be periodically purged safely away.
Operating smoothly across demanding pressure variables, the DCF-400 system safely minimizes product loss, operator exposure, material handling challenges, and structural waste footprints across adhesive, chemical, ink, petro-chemical, and commercial food production facilities.
High Viscosity Optimization: The DCF-400 maintains a constantly low, highly predictable differential pressure drop across the filter housing by utilizing an internal spring-loaded scraping disc. This disc continuously clears collected particulates from the clean filtration matrix face without stalling production streams. Applicable for viscosities up to 50,000 cps.
Unfiltered process fluid enters through the 1½" male NPT inlet port, passing directly into the internal center-point of a specialized cylindrical slotted wedge-wire screen. As the liquid progresses outward from the inside diameter (ID) of the matrix toward the outlet port, suspended contaminants, gels, and coarse fibers are securely intercepted along the inner screen wall.
At targeted intervals, an automatic pneumatic stroke cylinder drives a spring-loaded mechanical cleaning disc down and back up the interior screen surface. This dual-directional stroke instantly shears accumulated cake away from the fluid flow path and drives it downward into the isolated 0.06-gallon bottom purge chamber. The automated flush valve releases concentrated residue cleanly with negligible product loss, all while clean fluid continuously flows downstream without pressure spikes or process disruptions.
