The Eaton DCF-2000 is a premier, high-capacity mechanically cleaned filter system engineered for industrial process lines requiring continuous, high-volume flow rates under extreme viscosity conditions. While standard bag or cartridge filters incur high recurring overhead and labor downtime, the media-free design of the DCF-2000 delivers continuous operation without replacement elements.
Unlike smaller configurations that use traditional pneumatic actuators, the DCF-2000 leverages a specialized motor-driven drive screw design. Plunging pneumatic shafts require constant high-maintenance dynamic seals to prevent fugitive product emissions along the stroke line. The DCF-2000 eliminates this systemic vulnerability by substituting a reliable, heavy-duty common rotary seal configuration.
This direct screw-style mechanical shaft provides substantially higher downward force than fluid or air cylinders. Consequently, the DCF-2000 easily shears through thick, highly sticky, and heavily concentrated slurries that would stall out pneumatic filtration equipment.
High Viscosity Mechanical Performance: By continuously cleaning the interior surface of its heavy-duty wedge-wire screen, the DCF-2000 maintains a consistently low, predictable differential pressure drop across the pipeline. It is uniquely optimized to process heavy paper coatings, concentrated chemical compounds, resins, viscous adhesives, recycling wash matrices, and high-volume food production streams.
Unrefined fluids enter the top inlet port of the filter body and transition into the interior of a heavy-duty, cylindrical slotted stainless steel screen element. The fluid path travels from the inside outward through the screen matrix, safely trapping suspended particulates, thick gels, and raw fibers against the inner diameter (ID) of the element walls.
At pre-programmed automation intervals, the electric motor drive turns an internal drive screw to move a wide, spring-loaded mechanical cleaning disc down and back up the screen cylinder. This robust mechanical scraping action lifts collected cake and debris away from the fluid path and directs it safely down into the bottom purge isolation chamber. When the automated purge valve opens, concentrated contaminants are flushed quickly from the system with minimal product loss. Full process flow to downstream systems continues uninterrupted throughout the entire cleaning cycle.
