Description
The OASE ProfiClear Premium DF-L Gravity-Fed Drum Filter is a professional mechanical filtration unit designed for koi ponds and high-performance gravity-fed systems.
It acts as the primary filtration stage, removing fine and coarse debris from the water before it enters biological filtration chambers.
Water flows naturally from the pond into the drum filter by gravity, passing through a fine stainless-steel mesh screen that captures suspended solids and waste particles.
When the screen becomes blocked, an automatic cleaning system activates, flushing debris away without interrupting system performance or flow.
The DF-L is designed as part of the ProfiClear modular filtration system, making it ideal for compact yet high-performance koi pond installations.

How It Works
- Water flows from the pond into the drum filter by gravity
- Water passes through a fine stainless-steel mesh drum screen
- Waste particles are trapped on the drum surface
- Clean water passes to biological filtration stages
- When clogged, an automatic spray system cleans the drum
- Waste is flushed to drainage
Where This Product Sits
The DF-L Gravity unit is a mechanical pre-filtration component only within the ProfiClear system.
It sits within:
- Gravity-fed koi pond systems
- Modular ProfiClear filtration builds
- Professional pond installations
It is NOT:
- A complete filtration system
- A biological filter
- A standalone pond solution
It must be paired with:
- ProfiClear moving bed biological chamber
- Air pump system
- Return pump or gravity return system
Installation
- Gravity-fed configuration only
- Installed below pond water level
- Requires correct hydraulic design
- Connected to biological filtration chamber
- Waste outlet required for cleaning discharge
Maintenance
- Minimal due to automatic cleaning system
- Periodic inspection of spray nozzles
- Check waste outlet line
- Inspect seals and drum mechanism
- Routine system checks
Range Positioning
| Range | Purpose |
|---|---|
| ProfiClear DF-L Gravity | Compact gravity-fed drum filter unit |
| ProfiClear DF-XL Gravity | Large gravity-fed drum system |
| ProfiClear Moving Bed | Biological filtration chamber |
| ScreenMatic² | Alternative mechanical filtration |
Key Benefits
- High-efficiency mechanical filtration
- Ideal for gravity-fed koi systems
- Protects biological filtration stages
