Reliable Air Supply for Pond Aeration
The Enviro ET30 is suitable for pond aeration systems where a consistent air supply is needed to support water movement and oxygen transfer.
Connected to suitable air diffusers or air stones, the pump distributes air into the water, creating bubbles and circulation. This helps increase contact between water and air and supports dissolved oxygen levels.
Pond aeration can be particularly valuable in:
Koi ponds.
Garden ponds.
Fish-holding systems.
Aquaculture installations.
Pond filtration systems.
The appropriate pump size depends on pond volume, water depth, diffuser resistance and the number of air outlets. The ET30 should be selected according to the required airflow at the operating pressure, rather than airflow alone.
Suitable for Wastewater and Septic Tank Aeration
The Enviro ET series is also designed for wastewater aeration applications.
Supplying air to an appropriately designed treatment system helps maintain oxygen availability for aerobic microorganisms involved in biological wastewater treatment.
The ET30 can be considered for suitable:
Domestic wastewater treatment systems.
Septic treatment installations designed for aeration.
Small wastewater aeration applications.
Biological treatment systems requiring a low-pressure air supply.
Always check the airflow and pressure requirements of the treatment system before selecting the pump.
Efficient 25 W Operation
The ET30 delivers its rated airflow while consuming only 25 W of electrical power.
This makes it an attractive option for installations where the pump needs to operate for extended periods.
Its principal performance specification is:
30 litres per minute at 0.12 bar
Actual airflow changes with operating pressure and the resistance of the connected air distribution system. Long air lines, small-diameter pipework, deep water and restrictive diffusers can all affect delivered airflow.
Weather-Resistant and Compact Construction
The Enviro ET30 has a robust, compact housing designed for use in suitable indoor and outdoor environments.
Its dimensions are approximately:
208 × 150 × 178 mm (L × W × H)
The compact design makes it easier to position close to a pond filtration system, wastewater treatment installation or other aeration equipment.
For outdoor installations, position the pump in a location that protects its electrical connection and prevents water ingress, flooding or excessive exposure to standing water. Follow the manufacturer's installation instructions.
Maintenance and Service Kits
The Enviro ET30 is designed to be serviceable, with replacement service kits available.
Charles Austen recommends servicing its enviro pumps at least every 18 months. Regular maintenance helps maintain reliable operation and allows wear components to be replaced before they cause a loss of performance.
The ET30 service kit includes components such as diaphragms and filters.
Maintenance should be carried out according to the manufacturer's service instructions, with the electrical supply disconnected before opening the pump.

Installation and maintenance
Install the pump on a stable, suitable surface in accordance with the manufacturer's instructions. Use compatible airline, fittings and diffusers, and ensure that the total system resistance does not exceed the pump's operating capability.
For multiple outlets, a suitable air distribution manifold can help divide the airflow between individual diffusers. The airflow available at each outlet will depend on the number of outlets, airline dimensions, diffuser resistance and operating pressure.
Charles Austen recommends servicing Enviro pumps at least every 18 months. Replacement service kits are available and routine maintenance helps keep the pump operating correctly.
Why choose the Charles Austen Enviro ET40?

Installation and maintenance
Install the pump on a stable surface in a suitable, ventilated location, following the manufacturer's installation instructions. Although the pump has weather-resistant construction, it should be installed and protected appropriately for its environment.
Use compatible airline, fittings and diffusers. For installations with several aeration points, an air distribution manifold can divide the output between individual outlets.
The pump's actual airflow at each diffuser will depend on operating pressure, water depth, airline dimensions, diffuser resistance and the number of connected outlets. The rated 60 L/min figure should therefore be treated as a manufacturer specification at 0.12 bar, rather than a guaranteed flow at every outlet.
Charles Austen recommends servicing Enviro pumps at least every 18 months. Replacement service kits are available to support routine maintenance and help maintain correct operation.
Why choose the Charles Austen Enviro ET60?
The ET60 is a strong option for pond owners, hydroponic growers and water-system operators who need a higher-volume air supply from a compact, serviceable pump.
With a rated output of 60 L/min, 55W power consumption and an 18mm outlet, it is particularly suited to larger aeration systems and installations supplying multiple diffusers.
Choose the Charles Austen Enviro ET60 for dependable, high-volume aeration in ponds, koi systems, hydroponics and other suitable low-pressure air applications.
