How the Charles Austen Air Pumps Work:

The Charles Austen Air Pump range are pieces 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. These air pumps will drive air at a rate of at least 30 litres per min, rising to 120 litres, through an airline tube and into a series of airstones, which are submerged in water / nutrient solution.

How to use the Charles Austen Air Pump:

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. The airstones can then be placed in your desired areas.

Please Note: These pumps have a large diameter outlet. A manifold (sold separately) is required to use these pumps with 4mm (inner diameter) airline. An L-shaped piece of connection tubing and 2 clips are provided for connecting your manifold with. Never immerse the pump in water!
