Charles Austen Air Pumps
Browse diaphragm, piston, compressor and specialist aeration ranges by series
This parent section keeps the complete Charles Austen range organised without overwhelming the main Air Pumps category. Open the relevant series to compare models, then use the airflow and pressure filters to narrow the wider air-pump range by performance.
Choosing a Charles Austen Air Pump
Match the pump to the airflow required at the real working pressure created by water depth, airline and diffuser resistance. For help, send us the pond or treatment-system details, diffuser type, depth and airline length.
