How the Ex-DisplayCharles Austen ET120 Air Pump - 120 Litres/min Works:

The Charles Austen ET120 is a piece of precision-engineered equipment, ideal for oxygenating nutrient reservoirs. Air pumps are typically used in deep water culture systems and WaterFarms / AquaFarms – though every nutrient tank can benefit from oxygenation. The ET120 will drive air at a rate of 40 litres per min through an airline tube and into an airstone, which is submerged in water / nutrient solution.

How to use the Charles Austen ET120 Air Pump - 120 Litres/min:

Always position your pump in a raised area, using a stand or shelf, etc., so that it sits above the waterline of the pump’s destination reservoirs or system. This removes the chances of any water siphoning back towards the pump should the unit be accidentally switched off or in the event of a power failure. Check valves are a recommended safety precaution. Cut your air line in two and use the two barbed inlet / oulet points on the check valve to join it back together. The black end should be joined to the air line tubing coming from the air pump and the clear end should be fitted to the air line that moves on out towards the airstone.

A manifold will need to be purchased separately in order to connect this pump to standard-sized 4mm (inner diameter) airline tubing. Connect the L-shaped piece of rubber tubing, which is supplied with the pump, to the air outlet point. Fit the manifold into the rubber tubing and secure it in place using the two provided clips. Manifolds can be purchased in different sizes, depending on the number of airstones you wish to supply. Each manifold has a different number of 4mm outlets that can be opened or closed with their own valve, giving you complete control over air direction. Connect suitably long 4mm airline tubes to the outlets of the manifold and insert airstones into the ends of the each one. It is best to try to keep the air lines as short as possible because the air pressure will be reduced the longer they are. These airstones can then be placed in your desired areas.

Please Note: This pump has a large diameter outlet. A manifold (sold separately) is required to use this pump with 4mm (inner diameter) airline. An L-shaped piece of connection tubing is provided for connecting your manifold with. However, some form of clip, such as a hose clip may be required to secure a manifold to it. Never immerse the pump in water!
