Red Label PRO Drum 50/55 XL Drum Filter
High-Capacity Automatic Drum Filtration for Large Koi Ponds
The Red Label PRO Drum 50/55 XL drum filter is a gravity-fed mechanical filtration system designed for large koi pond installations that require high flow capacity, stable hydraulic performance, and integrated ultraviolet sterilisation.
Manufactured from polypropylene with stainless steel filtration components, this drum filter provides corrosion resistance and long service life in wet filtration environments.
The Red Label 50/55 XL drum filter uses this construction approach to provide stable long-term operation in gravity-fed pond filtration systems.
Construction of the Red Label 50/55 XL Drum Filter
The filter housing uses polypropylene, while the drum screen panels use INOX stainless steel.
Manufacturers commonly select polypropylene because it resists corrosion, maintains structural stability, and performs reliably under continuous water exposure. Consequently, many professional drum filters use similar material combinations.
Mechanical Filtration Performance of the Red Label 50/55 XL
The filtration system uses a 70-micron stainless steel screen to remove suspended solids from circulating pond water.
Most professional drum filters operate within a 60 to 100 micron range. Therefore, this filtration level removes fine waste while maintaining stable flow rates.
Because of this filtration design, the Red Label 50/55 XL provides consistent removal of suspended solids before biological filtration occurs.

Hydraulic Stability and Reception Chamber Design
The enlarged reception chamber increases buffering capacity. As a result, it helps stabilise operating water levels during high-flow conditions and supports consistent drum operation.
This hydraulic buffering supports stable operating conditions for the Red Label 50/55 XL drum filter during high flow rates.
Integrated UVC Configuration
The filtration system includes a built-in 80-watt stainless steel UVC unit.
Integrated UVC systems provide a compact installation layout. In addition, they protect the UVC chamber within the filtration housing.
The integrated sterilisation system forms part of the complete filtration design of the Red Label 50/55 XL.
Automated Cleaning Operation
The drum filter uses an automatic spray bar cleaning system controlled by a water level sensor.
This system rotates the drum, flushes debris from the mesh, and discharges waste through the outlet channel. Consequently, it maintains consistent filtration performance while reducing manual maintenance.
Installation Requirements
For correct operation:
Install the drum filter on a level, stable base.
Align the drum operating water level with the pond datum level.
Allow for water level drawdown when pumps operate.
Set gravity return pipework at the correct operating height.
Incorrect installation can cause unstable water levels and improper drum operation.
How Drum Filters Work in Koi Pond Filtration Systems
A drum filter removes suspended solids before biological filtration occurs. Water passes through a rotating stainless steel mesh screen that captures debris while filtered water continues to the biological stage.
As debris accumulates, internal water levels rise. The cleaning system then activates automatically. Spray jets flush waste from the mesh, and the drum returns to normal filtration.
