T5 Automatic Rotary Drum Pond Filter | 1,345 GPH / 1,320-Gallon (5-Ton) Capacity | Self-Cleaning Backwash & Biochemical Filtration – Koi Pond, Aquaculture & Freshwater Drum Filter System

The T5 Automatic Rotary Drum Pond Filter is a mid-range, hobbyist-grade pond filtration system built for koi ponds, small aquaculture farms, and freshwater systems up to 1,320 gallons (5 tons). Sitting one step above the T3 in the product line, the T5 delivers 1,345 GPH of continuous mechanical micro-filtration and biochemical biological filtration — with fully automatic self-cleaning backwash that keeps maintenance effort to an absolute minimum.

Water enters the 316 food-grade stainless steel rotary drum filter screen axially and flows radially through the mesh, which captures all suspended particles ≥50 μm — including fish waste, fine sediment, algae, and organic debris. When debris builds up to the threshold level, the intelligent automatic water-level control system activates a timed high-pressure backwash cycle: the drum rotates as pressurized nozzles flush all trapped impurities directly to the sewage outlet for discharge — completely hands-free. Once the timed cycle ends, the system returns to normal filtration automatically.

Constructed from food-grade PP material rated for 10+ years of continuous outdoor use, the T5 withstands prolonged exposure to UV, heat, rain, and corrosion without loss of performance. Its inclined-bottom chamber design eliminates dead zones and ensures complete sewage drainage with every backwash cycle, while the built-in biochemical filtration stage rapidly cultivates beneficial nitrifying bacteria for stable, long-term water clarity.

The integrated buffer pool design prevents leakage of suspended matter at the inlet, ensuring no bypass of unfiltered water — a key feature often missing in lower-cost alternatives.
