ProfiClear Premium DF-XL gravity OC

Very large koi ponds demand serious mechanical filtration. If solid waste isn’t removed immediately, it breaks down, increases ammonia load and puts pressure on the biological stage. The OASE ProfiClear Premium DF‑XL Gravity OC is a high-capacity automatic drum filter designed specifically for gravity-fed koi pond systems.

It delivers fine mechanical separation at the very first stage of filtration, protecting everything that follows.

 

Built for Gravity-Fed Systems

This model is designed to sit at water level in a gravity-fed setup, typically connected directly to bottom drains and skimmers.

Typical layout:
Bottom drain / skimmer → DF‑XL Gravity Drum → Biological module(s) → Pump chamber → Return to pond

Because it operates under gravity flow, correct pond and filter height alignment is essential before installation.

 

Key Features

• 60‑micron stainless steel drum screen
• Fully automatic self-cleaning system
• High-capacity design for large flow rates
• Modular integration within the ProfiClear Premium system
• Heavy-duty construction for demanding koi ponds

This is a dedicated mechanical stage. Its job is simple: remove solids before they dissolve and compromise water quality.

 

How the Drum System Works

Water flows into the drum chamber under gravity. The 60‑micron screen captures fine solids as water passes through.

As debris builds on the screen, sensors trigger an automatic cleaning cycle. The drum rotates while high-pressure spray nozzles rinse waste into a discharge trough and out to waste.

The result:

• Immediate solid waste removal
• Reduced organic breakdown
• Improved efficiency of downstream biological filtration
• Greater long-term system stability

 

Installation Considerations

• Designed for gravity-fed pond builds
• Requires adequate waste outlet for cleaning discharge
• Must be installed at correct water level
• Intended to integrate with ProfiClear Premium biological modules and pump chambers

Always confirm pipe sizes, flow rates and system layout before installation.

 

Maintenance

Cleaning cycles are automatic, but routine inspection is still important:

• Check spray bar and drum screen periodically
• Ensure waste outlet remains clear
• Inspect seals and connections
• Isolate electrical supply before servicing

Consistent checks protect long-term performance.

 

Who It’s For

• Very large koi ponds
• Heavily stocked systems
• Multi-bottom drain installations
• Keepers building professional, modular filtration systems
