Frequently asked questions
What is the Charles Austen AC Series air pump best for?
The AC Series piston pumps are ideal for larger hydroponic tanks and aquariums. They let you run several air stones from one pump so a large volume of water can be aerated at once.
Which AC Series model should I choose?
Output runs from the AC35 (35 l/min, 18W) up to the AC275 (275 l/min, 175W), with seven sizes in between. Choose a higher flow if you are running more air stones or a bigger reservoir.
What comes with the Charles Austen AC Series pump?
Each pump is supplied with a barbed brass connector and manifold. The robust piston design is virtually maintenance free and has low power consumption.
