Oase ProfiClear Premium XL Rotary Drum Filter System Gravity Fed
The OASE ProfiClear Premium XL Gravity-Fed is a professional-grade, fully automatic modular filtration system designed for serious koi ponds and swim ponds. This advanced system combines rotary drum mechanical filtration, moving bed biological filtration, and high-level aeration to deliver crystal-clear water with minimal maintenance.
Key Features:
- Fully automatic self-cleaning rotary drum filter
- Modular design allows customization for any pond size
- Drum filter removes debris down to 60 microns
- Built-in high-pressure cleaning pump for automatic drum rinsing
- Moving bed biological filtration strips ammonia and nitrites
- High-level aeration throughout all modules
- Sensor-based, timed, or manual cleaning options
- Integrated sludge drains in all modules for easy maintenance
- Remote operation and monitoring via OASE Control app (requires Garden Cloud Controller, sold separately)
- Qualifies for OASE Clear Water Guarantee with proper UVC
Gravity-Fed Installation:
Gravity-fed systems install at or below pond level, typically in an underground vault. Dirty water flows naturally from your pond (via bottom drains or skimmers) into the filter system by gravity. After filtration, a pump housed in the discharge module returns clean water to your pond. This design is the gold standard for serious koi ponds, providing superior filtration and reliability.
How the System Works:
- Mechanical Filtration: The Drum Filter Module sieves incoming water down to 60 microns, automatically cleaning itself via high-pressure spray
- Biological Filtration: Moving bed and standing bed modules process dissolved waste, breaking down ammonia and nitrites
- Aeration: Integrated aeration throughout modules adds oxygen and supports beneficial bacteria
- Return: Pump in discharge module returns clean, clear water to your pond
Modular Design Benefits:
- Customize system size by adding modules to match your pond volume and fish load
- Start with essential modules and expand as needed
- Each module serves a specific filtration purpose
- Easy to maintain—each module drains independently via sludge valve
Smart Control Options:
- Operate and monitor remotely via OASE Control app
- Requires OASE Garden Cloud Controller (sold separately)
- Monitor system status from anywhere in the world
- Adjust settings and receive alerts remotely
Perfect For:
- Serious koi ponds and show-quality koi
- Swim ponds and natural swimming pools
- Professional koi keeping
- High-end residential water features
- Ponds requiring maximum filtration capacity and reliability
Note: System is modular—contact us for custom configuration based on your pond size and requirements. Garden Cloud Controller sold separately. Requires bottom drains or gravity-fed intake system.
Frequently Asked Questions
Q: What's the difference between gravity-fed and pump-fed ProfiClear XL systems?
A: Gravity-fed systems (like this one) install at or below pond level, typically in an underground vault. Water flows naturally from bottom drains to the filter by gravity, and a pump in the discharge module returns clean water to the pond. This is the preferred setup for serious koi ponds because it's more reliable and efficient. Pump-fed systems install above pond level—a pump pushes water up to the filter, and clean water returns by gravity. Pump-fed systems offer more flexible installation but gravity-fed systems are superior for koi keeping.
Q: Do I need bottom drains for a gravity-fed system?
A: Yes, gravity-fed systems work best with bottom drains installed in your pond. Bottom drains allow water (and debris) to flow naturally from the pond bottom to the filter by gravity. This is the most effective way to remove waste from koi ponds. You can also use gravity-fed skimmers in combination with bottom drains. The system requires professional installation with proper plumbing and an underground vault to house the filter modules.
Q: How do I know which modules I need for my pond?
A: The ProfiClear Premium XL is a modular system customized based on your pond volume, fish load, and filtration goals. At minimum, you'll need the Drum Filter Module for mechanical filtration and a Discharge Module. Add Moving Bed and/or Standing Bed modules for biological filtration based on your fish load—heavily stocked koi ponds need more bio-filtration capacity. We recommend consulting with an OASE dealer or pond professional to design the optimal configuration. Contact us with your pond details for a custom recommendation.
