The Charles Austen Enviro ET60 is a high-output, oil-free linear diaphragm air pump designed for pond aeration, koi ponds, hydroponic systems, aquaculture and other applications requiring a dependable supply of air.

Delivering a rated airflow of 60 litres per minute at 0.12 bar, the ET60 is designed for larger installations and systems that need more airflow than smaller pond and aquarium air pumps can provide. It can supply multiple air stones or diffusers through a suitable distribution manifold, making it a practical solution for larger ponds, growing systems and water treatment applications.

The ET60 combines a robust, compact and weather-resistant design with Charles Austen's energy-efficient Green Drive technology. With a power consumption of 55W, it provides a substantial airflow capacity for regular or continuous aeration applications.

Key features

• 60 L/min rated airflow: Delivers up to 60 litres per minute at the manufacturer's specified pressure point of 0.12 bar.

• 55W power consumption: Designed to provide high airflow with relatively low electrical consumption for its output class.

• Oil-free air supply: Linear diaphragm pump technology operates without oil lubrication.

• 18mm air outlet: Suitable for connection to compatible airline fittings and air distribution systems.

• Weather-resistant construction: Robust housing designed for suitable indoor and outdoor installations.

• Multiple diffuser applications: Can supply several air stones or diffusers when connected to an appropriately sized manifold.

• Serviceable design: Compatible replacement service kits are available to support routine maintenance.

• Rubber elbow supplied: Manufacturer information identifies a rubber elbow as part of the ET-series fitting arrangement.

Suitable applications

Pond and koi pond aeration

The Enviro ET60 provides a substantial air supply for larger ponds and koi systems. Connect it to compatible pond diffusers to introduce air into the water and support circulation and oxygen transfer.

The number and type of diffusers required will depend on pond depth, volume, diffuser resistance and the desired aeration level.

Hydroponics and deep water culture

The ET60 is suitable for hydroponic installations requiring a higher-volume air supply. It can feed multiple air stones, air domes or other compatible diffusers, helping to aerate nutrient solution in deep water culture systems.

Aquaculture and fish-rearing systems

For suitable aquaculture installations, the ET60 can provide air to multiple aeration points. Correct diffuser selection and airflow distribution are important to ensure that the system receives the required aeration.

Wastewater aeration

The Charles Austen Enviro ET series is also designed for wastewater applications. Aeration can support aerobic biological processes by supplying air to the treatment system.

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.
