CAP Rotary Drum Filter AG-RD5

This all-in-one filtration machine is manufactured from a highly durable, marine-grade Polypropylene (PP) plastic housing. It combines multi-stage mechanical and biological filtration loops inside a single compact footprint. The system sits directly on or alongside the pond basin, collecting raw water, separating solid waste via a motorized micro-mesh drum, and funneling the water through integrated biological stages before returning it crystal-clear to the aquatic environment. 

Features

• Automated Mechanical Separation: Raw pond water passes into a horizontal, rotating micro-mesh screen drum that instantly traps fish feces, uneaten food, and loose debris.
• Smart Backwash Rinsing System: Internal level sensors detect debris buildup. Upon restriction, an external smart controller engages a row of high-pressure spray nozzles to wash the waste directly down an integrated gutter and out the sewage line.
• Multi-Stage Combi Chamber: Features a dedicated biological section lined with structural bottom grates, optimized for housing moving-bed bio-media (such as K1/K5) to process dissolved toxic ammonia and nitrites.
• Weatherproof Smart Control Panel: A side-mounted, waterproof microcomputer panel coordinates automated rinsing schedules, sensor triggers, and power management.
• Heavy-Duty Construction: Built entirely out of UV-resistant, chemical-proof Polypropylene with marine-grade 316L stainless steel screen components to protect against structural corrosion. 

Zero Manual Maintenance

• No More Sponge Washing: You no longer need to manually pull out, squeeze, or rinse heavy, clogged filter pads or foam mats.
• Worry-Free Travel: The filter runs independently for weeks or months at a time, allowing you to leave your pond unattended without risking a filter clog.
  

Ultimate Water Clarity & Quality

• Micro-Particle Removal: The 70–75 micron mesh screens out microscopic waste, floating algae, and fish feces before they can break down.
• Instant Waste Export: By instantly separating solid waste and flushing it out a dedicated drain line, it prevents fish waste from dissolving into the water.
• Reduced Ammonia & Nitrate: Removing solids immediately keeps the chemical load low, significantly easing the burden on your biological filtration stage.🐠
  

Healthier Aquatic Environment

• Stable Parameters: Eliminates the massive spikes in ammonia and nitrites caused by decaying organic matter sitting inside traditional filters.
• Higher Oxygen Levels: Less organic decay means heterotrophic bacteria consume far less oxygen, leaving more dissolved oxygen available for your Koi or fish.
• Optimized Bio-Media: The dedicated bio-chamber stays free of physical sludge, allowing beneficial nitrifying bacteria to colonize the moving-bed media with maximum efficiency.

Quick Facts

• Filter Classification:  Fully Automated Combi Rotary Drum Filter (RDF)
• Typical Flow Rating: Upto 5000 Liters
• Mesh Filtration Rating: Fine 70 to 75 Microns particle screen
• Housing Material: Anti-corrosive Polypropylene (PP) sheet
• Target Application: High-end Koi ponds, public exhibits, and aquaculture
• Primary Advantage: Eliminates manual sponge/pad cleaning entirely

• Water Savings: It targets only the dirty mesh during backwashing, using significantly less water than traditional pressure filters that require long, heavy manual backwash cycles.
