Overview
The Pureflow Rotary Drum Filter is a high-performance automatic pond filter designed for koi ponds, fish ponds, and advanced RAS filtration systems. As water passes through the system, it immediately captures fine suspended solids, significantly improving water clarity, reducing organic load, and supporting optimal water quality for aquatic life.
Moreover, the filter features an automated backwash process, so it operates continuously while requiring minimal maintenance. At the same time, it consumes very little energy, which ensures cost efficiency. Since it is built with corrosion-resistant food grade polypropylene, it performs reliably for years in both freshwater and saltwater environments.
In addition, the Pureflow Drum Filter suits ornamental koi ponds, garden fish ponds, public aquariums, and commercial hatcheries. Because of its scalable design, it adapts seamlessly to both small setups and large RAS facilities. Consequently, users achieve sustainable, precise, and dependable water management without hassle.
Ultimately, when you need crystal-clear water, lower organic waste, and long-term reliability, Pureflow stands as the trusted solution for modern aquatic filtration.
Pureflow Biofloc Drum Filters provide automatic, fine-particle filtration that keeps water crystal clear while promoting healthier fish. Since they use advanced micron mesh screening, they remove solid waste before it breaks down. As a result, ammonia levels decrease, and biofiltration efficiency improves significantly.
Because these filters are designed for both freshwater and saltwater applications, they suit a wide range of needs. Whether you require a gravity-fed setup or a pump-fed design, our solutions adapt effortlessly. Therefore, they work perfectly for small hobby ponds, ornamental koi ponds, or large-scale aquaculture tanks and RAS filtration systems.
Key Advantages and Applications
Features
Benefits
- Wide range of flow rates: 1m³/h – 4000 m³/h or 4.4 gpm – 17611 gpm.
- Drum filters use automatic pond filter, fine mesh screens (typically 20–75 microns) to capture suspended solids before they break down, improving water clarity and quality.
- 2. Filtration Through Micron MeshThe rotating drum is lined with a fine mesh screen (typically 20–75 microns) that traps solid particles while clean water passes through to the outlet
- A quality RDF made from polypropylene or stainless steel can last 10–15 years or more.
