OASE ProfiClear Premium DF-L Gravity-Fed
The OASE ProfiClear Premium DF-L Gravity-Fed is a professional-grade automatic drum filter designed for large koi ponds, heavily stocked fish ponds and premium ornamental water features. As part of the modular ProfiClear Premium filtration system, it provides exceptionally fine mechanical filtration while allowing the system to be expanded with biological Moving Bed and other filtration modules.
The gravity-fed configuration provides outstanding hydraulic efficiency, with a maximum flow capacity of 33,000 L/h. Up to four DN 110 inlets can be connected, making the filter particularly suitable for ponds using multiple bottom drains, skimmers or gravity-fed intake lines.
The stainless steel drum removes suspended solids down to approximately 60 microns, while an intelligent microcontroller automatically monitors the filter and activates the cleaning cycle when required. A powerful 6 bar rinsing pump cleans the drum screens automatically, significantly reducing routine maintenance.
