DCF Mechanically Cleaned Filter Systems

The Benefits of Automation

DCF automated filtration systems are engineered to replace traditional filter bag and cartridge systems, drastically reducing your facility's operating costs. The DCF-Series was specifically developed for non-water applications involving highly viscous, abrasive, or viscoelastic liquids. Key advantages include:

• Cost Reduction: Eliminates the recurring costs of replacement filter media and its associated disposal.
• Improved Safety & Yield: Reduces employee interaction with filtered liquids (lowering injury risks) and minimizes product carry-out/loss during change-outs.
• Process Consistency: Maintains a continuous, low differential pressure, eliminating the pressure spikes typical of manually maintained filtration systems.

How Mechanically Cleaned Filters Work

The DCF design provides incredibly simple and reliable operation:

1. Inflow: Liquid flows into the top of the filter station, travels down through the center of the element, passes through the element walls, and exits the outlet.
2. Trapping: Because the top of the element is sealed, all unfiltered liquid must enter the element. Large particles fall to the bottom or stick to the inner element wall.
3. Cleaning Stroke: A spring-loaded cleaning disc travels the length of the 316SS element at a user-programmable frequency. It pushes stuck material down into the bottom "purge chamber" without damaging the element.
4. Purging: The concentrated solids in the purge chamber are flushed out when the drain valve opens. The flush utilizes system pressure versus atmospheric pressure, usually taking only a second or two.

Specialized DCF Filtration Systems

We offer various models depending on flow rates and fluid characteristics:

• DCF-2000 (Pulp & Paper): Features an electric motor-driven cleaning disc. Handles up to 72% solids at a fine 75-micron retention. The disc continuously sweeps and agitates the purge chamber to keep solids semi-liquid.
• DCF-FRY OIL: Built with FDA-approved materials and insulation for filtering hot fry oil up to 400°F, replacing vibratory and paper band filters.
• Multiplexed Systems: For capacities exceeding 1500 GPM, models like the DCF-1600, DCF-2000, and DCF-3000 can be connected to a common inlet, outlet, and purge manifold with customized PLCs.
• MCF-824 (Magnetically Actuated): Uses powerful rare earth magnets to drive the cleaning disc, eliminating external physical linkages. Ideal for hazardous liquids or tight spaces. Rated for up to 200 GPM at 30-150 PSIG and ≤180°F.
