Oase ProfiClear Premium Moving Bed Module L

Oase ProfiClear Premium Moving Bed Module L

High Capacity Moving Bed Biological Filtration Module

The Oase ProfiClear Premium Moving Bed Module L is a dedicated biological filtration chamber designed to expand and enhance ProfiClear Premium modular filtration systems. Engineered for koi ponds, fish ponds and large ornamental installations, it provides powerful nitrification through a fluidised Hel X moving bed process. As a result, it significantly improves biological stability in high demand pond environments.

Designed primarily for gravity fed systems, the Moving Bed Module L connects directly to the ProfiClear Premium Drum Filter Module. Therefore, it operates as the second stage of filtration, processing dissolved pollutants after mechanical separation has taken place.

Advanced Hel X Biological Processing with Aeration Support

At the core of the module sits Oase Hel X biomedia, which offers up to 806 m² per cubic metre of protected surface area. Consequently, it provides substantially more bacterial settlement space compared to traditional K1 style media. This increased surface area allows beneficial bacteria to colonise effectively and break down ammonia, ammonium and nitrite.

The integrated aerator bar at the base of the chamber ensures continuous oxygen supply. When connected to an air pump, the system maintains constant media movement. As a result, the fluidised bed process prevents clogging, eliminates dead zones and supports consistent bacterial activity.

The module is designed to handle flow rates up to 25,000 litres per hour. In addition, bypass technology ensures optimal circulation even under higher flow conditions. Therefore, the Moving Bed Module L remains stable in demanding koi pond setups.

A slide valve flush system with DN 75 discharge allows simple removal of settled debris when required. Furthermore, the durable construction ensures long term reliability within professional filtration installations.

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 a compatible DN75 outlet/discharge pipework connection, so the matching discharge pipework can be useful when building, extending or repairing the return route from the filter.
