The Charles Austen Air Pump ET Series delivers reliable high-flow, low-pressure air supply for a wide range of applications, including koi ponds, aquaculture, wastewater treatment, and medical systems. These pumps maintain proper water movement, boosting oxygen levels to support aerobic bacteria and ensuring healthy aquatic environments.
Equipped with Green Drive technology, the ET Series is energy-efficient and consumes minimal power while delivering consistent performance. The specially formulated diaphragm material ensures long life, and the absence of wearing parts means there is no reduction in performance over time. Robust and compact, these weatherproof pumps are suitable for intermittent or continuous duty.
Each Charles Austen Air Pump is designed for easy maintenance. **Please note:** Charles Austen recommends servicing ET pumps at least every 18 months, and service kits for each model are available. This ensures optimal performance and longevity, making maintenance straightforward for both hobbyists and professionals. Whisper-quiet operation at as low as 35dB makes these pumps ideal for koi ponds, aquariums, and other installations where low noise is important.
Available in multiple sizes and compatible with standard air tubing, the ET Series air pumps provide dependable airflow, maximize oxygenation, and maintain water quality in all setups. Durable, energy-efficient, and easy to service, the Charles Austen Air Pump ET Series is the trusted choice for pond keepers, aquaculture operators, and industrial users seeking reliable and long-lasting aeration solutions.
