Oase ProfiClear Premium Compact M Gravity Fed OC

Professional Gravity Fed Drum Filtration for Larger Koi Ponds

The Oase ProfiClear Premium Compact M Gravity Fed OC is a high capacity self cleaning drum filtration system engineered for larger koi ponds and ornamental pond installations up to 80 cubic metres. Designed specifically for gravity fed systems, it combines precision mechanical filtration with powerful biological processing. As a result, it delivers exceptional water clarity and long term stability in demanding koi environments.

By integrating a 60 micron stainless steel drum screen with Hel X 13 moving bed biological media, the Compact M provides both immediate solid waste removal and continuous nutrient breakdown. Therefore, it is particularly suited to serious koi keepers who require consistent, professional level filtration performance.

Intelligent Drum Technology with Integrated Biological Processing

At the heart of the Compact M sits a precision 60 micron stainless steel drum screen. As water flows by gravity from bottom drains and skimmers into the drum chamber, the screen captures solid waste, uneaten food and fine suspended particles. Consequently, mechanical filtration occurs before water reaches the biological stage.

When debris accumulation begins to restrict flow, the automated cleaning cycle activates. High pressure spray jets rinse the drum surface and flush collected sludge into the discharge channel. As a result, the system continues operating efficiently without manual cleaning or interruption.

Following mechanical filtration, water enters the integrated moving bed chamber filled with Hel X 13 bio media. This high surface area media supports beneficial bacteria growth, which breaks down ammonia, ammonium and nitrite. Therefore, biological filtration remains stable even under higher stocking densities.

The Compact M Gravity Fed is designed to operate alongside the Oase ProfiClear Compact M Pump Chamber, which houses pumps and UVC units within the gravity system. We recommend pairing it with 2 x Oase AquaMax Gravity Eco 10000 pumps and 2 x Oase Bitron Premium 60W UVC clarifiers for optimal performance. In addition, the system is compatible with the Oase Control platform, allowing digital monitoring and remote management.

The insulated housing ensures quiet operation, while the modular design allows seamless integration within larger ProfiClear Premium filtration systems.

Technical information

• Match the pump flow to the filter and pond volume, allowing for head height and pipework losses.
• Keep unions, valves and waste outlets accessible for cleaning and maintenance.
• Use suitable hose, pressure pipe or DN discharge pipework where specified by the manufacturer.
• Check compatible UV bulbs, quartz sleeves, media and spare parts before the pond season starts.

Plan this product as part of the complete filtration layout, rather than as an isolated item. Check the recommended flow rate, inlet and outlet sizes, waste connection, access for cleaning and the space needed for routine servicing before installation. A well matched filter system is easier to maintain and gives more reliable water clarity over the long term.

Filter setup notes

Compatible Oase Discharge Pipework

This Oase product uses DN-sized outlet or sludge-discharge connections, so it is worth planning the pipework before installation. Use the matching DN pipework for the connection size stated on the exact filter or module, and avoid reducing gravity outlets unless the system has been designed for it.

• Oase DN110 Filter Discharge Pipework
