The Red Label Essential Drum 20/25 Gravity is a professional automatic drum filter designed for koi ponds and ornamental ponds. With a maximum flow rate of 25,000 litres per hour, it provides efficient mechanical filtration while automatically removing collected waste from the system.
Available from West Midlands Koi, this compact Red Label drum filter combines a 120-micron stainless steel screen, automatic cleaning, an integrated flushing pump and a built-in 40 W INOX UVC.
It is an excellent choice for pond keepers and professional installers looking for reliable mechanical filtration with reduced routine maintenance.
Professional Automatic Drum Filtration
The Red Label Essential Drum 20/25 Gravity works as a mechanical pre-filter.
Pond water enters the drum and passes through the stainless steel filter screen. Suspended debris is retained on the inside of the screen while the filtered water continues through the system.
As debris accumulates, the water level changes and the filter automatically starts a cleaning cycle. The drum rotates while the flushing system cleans the screen and directs the collected waste into the waste channel.
This automatic process restores flow through the screen without requiring regular manual cleaning of conventional filter media.
120-Micron Stainless Steel Screen
The Red Label Essential Drum 20/25 uses a 120-micron INOX stainless steel filter screen.
The screen captures suspended solids before they can continue further through the filtration system. Removing this waste at the mechanical stage can also reduce the amount of solid debris reaching subsequent biological filtration.
The stainless steel construction provides a durable filtration surface designed for continuous pond operation.
Automatic Cleaning System
Automatic cleaning is one of the main advantages of the Red Label Essential Drum 20/25 Gravity.
When cleaning is required, the control system starts a flushing cycle. The drum rotates while spray nozzles clean the filter screen. Waste removed from the screen is directed into the waste channel and discharged from the filter.
Once the screen has been cleaned, normal filtration continues automatically.
Therefore, the system can provide effective mechanical filtration while significantly reducing routine manual filter cleaning.
Integrated Flushing Pump
The Red Label Essential Drum 20/25 is supplied with an internal Q800103 flushing pump.
Integrating the flushing pump within the filter creates a compact installation and removes the requirement for a separate external flushing pump.
The pump supplies the cleaning system during an automatic rinse cycle, helping restore flow through the drum screen.
Built-In 40 W INOX UVC
A 40-watt INOX UVC unit is built into the Red Label Essential Drum 20/25.
The integrated UVC is designed to act against free-floating algae, bacteria and fungi in the water passing through the filtration system.
Integrating the UVC within the drum filter can also reduce the requirement for separate UV equipment within the external pond pipework.
Patented Red Label Drum Seal
Red Label drum filters feature a patented drum sealing system.
The sealing arrangement is designed to minimise water bypass around the drum so that water is directed through the filter screen.
A protective cover also helps shield the drum seal from UV exposure, supporting the long-term durability of this important component.
Double Brush Cleaning System
The Red Label drum design incorporates a double brush system.
This system helps keep the waste discharge channel clean as debris is removed from the drum. Consequently, the design helps reduce waste accumulation and supports easier routine maintenance.
Maximum Flow Rate up to 25,000 L/h
The Red Label Essential Drum 20/25 Gravity has a stated maximum flow rate of:
25,000 litres per hour
That is approximately:
5,500 UK gallons per hour
The manufacturer specifies the filter for ornamental ponds up to 40,000 litres and koi ponds up to 25,000 litres.
However, actual achievable flow and suitable pond volume depend on the complete installation. Factors such as pipe diameter, pipe length, bends, bottom drains, skimmers, pumps, head loss, stocking levels and feeding rates must also be considered.
West Midlands Koi can help specify the correct filtration and flow rate for your individual pond.
Gravity-Fed Koi Pond Filtration
This product is the gravity-fed version of the Red Label Essential Drum 20/25.
In a correctly designed gravity system, water travels from the pond through bottom drains and/or skimmers to the drum filter.
After mechanical filtration, the water can continue to the biological filtration stage before a circulation pump returns it to the pond.
A separate pump-fed version of the Red Label 20/25 is also available.

Why Choose a Red Label Drum Filter?
A drum filter continuously removes suspended solid waste from the pond water before it progresses through the filtration system.
Automatic cleaning means the screen does not need to be manually removed and cleaned during normal operation. Instead, the filter responds when cleaning is required and automatically flushes accumulated waste from the drum.
For koi ponds with substantial circulation and feeding rates, effective mechanical waste removal can form an important part of a professionally designed filtration system.
