Description

The Charles Austen CP120 Air Pump Battery Back Up is a powerful, dual-outlet aeration system designed to provide reliable oxygenation for koi ponds, aquaculture, wastewater treatment, and fish transportation. Unlike standard air pumps, the CP120 comes equipped with a built-in rechargeable 12V battery that keeps your system running for up to 8 hours during a power cut, ensuring fish stocks and aquatic systems remain safe and oxygenated when mains electricity is unavailable.

This high-output pump delivers 120 litres per minute across two 60 L/min outlets, offering greater flexibility for larger or multi-chamber systems. Its automatic power switching feature allows the pump to run from AC power during normal operation and seamlessly switch to DC battery power in the event of an outage. For pond keepers and aquaculture professionals, this built-in protection provides essential peace of mind during storms, electrical failures, or when transporting valuable fish.

One of the CP120’s most practical features is its variable flow control dial, which enables precise adjustment of airflow to match the environment. Whether you’re oxygenating a koi pond, boosting bacteria in a wastewater system, or running a transport vat, you can fine-tune the output to suit your needs. This not only improves efficiency but also helps prevent over-aeration and reduces stress for fish.

The unit is built with portability in mind, featuring an integrated retractable handle for easy movement and placement. Its oil-free design ensures contamination-free oxygen supply, while a LED indicator provides clear status updates, showing when the pump is running or needs recharging.

At just 35dB, the CP120 is exceptionally quiet, making it ideal for both domestic ponds and professional environments where low noise levels are important. It is also highly durable, supported by competitively priced service kits and covered by a two-year UK warranty.
