Keep your Charles Austen ET120 Series Air Pump running efficiently with this genuine ET120 Service Kit, designed specifically for the ET120, ET120A, and ET120AO linear diaphragm air pumps. This comprehensive maintenance kit contains the essential replacement parts required to restore airflow, maintain performance, and extend the operational life of your air blower.

Regular servicing is crucial for maintaining reliable aeration in septic tank systems, sewage treatment plants, and wastewater treatment applications. Over time, diaphragms, filters, and internal components naturally wear through continuous operation. Replacing these parts annually helps ensure consistent airflow, improved energy efficiency, and reduced risk of unexpected system downtime.

Why Choose a Genuine Charles Austen Service Kit?

Using genuine Charles Austen replacement parts ensures the correct fit, dependable performance, and long-term reliability of your air blower. This complete service kit provides everything needed for routine maintenance, helping to keep your ET120 series pump operating at peak performance throughout the year.


Warranty information

Charles Austen recommends that all air pumps and systems are serviced annually. Although the air pump carries a 2-year manufacturer's warranty, diaphragms, valves and filters are consumable parts that naturally wear over time and should be replaced during routine servicing to maintain warranty compliance and ensure reliable operation.
