The Eaton DCF-800 (originally engineered under the Ronningen-Petter brand) represents an industry benchmark for automatic, mechanically cleaned filtration. Sometimes referred to as a "scraper strainer," the DCF-800 is an automatic filter system providing element retentions ranging from as fine as 15 microns up to coarse openings of ¼”.
Applications that benefit most from the DCF-800 filter designs include highly viscous fluids, complex process chemicals where water backwashing is not viable, and continuous manufacturing flows requiring a steady, predictable differential pressure.
Conventional strainers and filter housings rely on media elements that quickly blind over when handling sticky or highly viscous products, causing differential pressure to spike rapidly. Manually removing or replacing those blinded elements inevitably causes significant process downtime and leads to the loss of expensive process fluids.
The DCF-800 eliminates these systemic bottlenecks. It features an internal cleaning disc that physically scrapes the screen element. By continually clearing accumulated solids away from the fluid path, it keeps downstream pressure drops perfectly managed without disrupting workflow or purging excess fluid.
Continuous System Integrity: Collecting and concentrating particulate waste inside the lower purge chamber means the system can open its flush valves quickly, expelling highly concentrated solids while losing only a fraction of the product volume compared to backwash alternatives.
