AIR‑AQUA BIO‑ROTATOR COMPACT‑S – High‑Efficiency Biological Filter

The AIR‑AQUA BIO‑ROTATOR COMPACT‑S is a next‑generation rotating biological contactor (RBC) designed for koi ponds and high‑load aquatic systems where biological stability, oxygenation, and reliability are essential. Using a rotating drum packed with high‑surface‑area media, the COMPACT‑S alternates exposure between air and water, delivering maximum oxygen transfer, rapid nitrification, and exceptional water clarity.

Compact, quiet, and extremely efficient, this unit is ideal for ponds where space is limited but performance cannot be compromised. Its self‑cleaning rotational action reduces maintenance while maintaining a powerful, stable bacterial colony.

Key Features

• Rotating Biological Contactor (RBC) for superior biological filtration
• High oxygen transfer for strong, stable nitrifying bacteria
• Compact footprint ideal for smaller filtration bays
• Low‑energy, quiet operation
• Self‑cleaning rotation reduces maintenance
• Perfect for koi ponds and high‑load systems
• Durable, long‑life construction

Technical Data

• Model: AIR‑AQUA BIO‑ROTATOR COMPACT‑S
• Flow rate: 20,000 litres per hour (20 m³/h)
• Bio media volume: 50 litres Hel‑X 17
• Filtration type: Rotating Biological Contactor (RBC)
• Power consumption: Low‑energy rotational drive
• Ideal pond size: Medium koi ponds / high‑load systems
• Noise level: Very low
• Maintenance: Minimal — rotation naturally oxygenates and cleans media

Performance Benefits

• Rapid ammonia and nitrite reduction
• Highly oxygenated environment for efficient bacterial colonies
• Consistent, stable filtration even under heavy feeding
• Reduced maintenance compared to static media systems
• Year‑round reliability

Installation & Positioning

• Suitable for gravity‑fed or pump‑fed systems (depending on setup)
• Install on a level base with clear space for rotation
• Works best when paired with strong mechanical pre‑filtration
• Ideal for filter bays, sheds, or enclosed filtration rooms

Care & Maintenance

• Check rotation periodically
• Keep bearings and drive components clean
• Maintain good pre‑filtration to prevent debris overload
• No manual media cleaning required

Recommended Pairings

• AquaForte Compact Sieve – ideal mechanical pre‑filter
• AquaForte DM‑Series Pump – efficient, reliable flow
• UV‑C Clarifier – crystal‑clear water
• Moving‑bed bio chamber – hybrid filtration setups

FAQ

Is the COMPACT‑S suitable for koi ponds

Yes — it is engineered specifically for high‑load koi systems.

Does the rotating media need cleaning

No — the rotation naturally oxygenates and cleans the media.

Is it noisy

No — it operates quietly with smooth, low‑energy rotation.

Can it integrate with existing filtration

Yes — it works with sieves, drums, bead filters, and pump‑fed systems.
