The JBL ProAir a400 is the two-channel model in the series and is designed for aquariums where air is needed in two places at the same time - e.g. for two air stones, two filter lifters, or separate tank areas. With a flow rate of 400 l/h and > 140 mbar, it offers noticeable power reserves even at higher counterpressure. Special feature of the a400: The air volume can be regulated electrically and additionally mechanically - for very sensitive adjustment to stocking, air stones, and desired surface movement. Power consumption 5 W, recommended for approx. 160-600 l, sound level 47 dB(A) (at 1 l/min).

For which aquarium sizes is the ProAir a400 intended?
For aquariums of approx. 160-600 liters.How many outlets does the a400 have - and what is the practical use of this?
It has 2 outlets. This allows two diffusers/applications to be operated in parallel or two zones in the aquarium to be specifically aerated.What are the key technical specifications of the a400?
400 l/h, > 140 mbar, 5 W, noise level 47 dB(A) (at 1 l/min).What exactly does electrically + mechanically adjustable mean?
From the a400 upwards, there is a mechanical air volume regulator in addition to the electrical control - this allows the air output to be adjusted with particular precision.There is not enough air - what are the typical causes?
Often the diaphragm is defective, the air filter is dirty, the diffuser is clogged, or the air volume control is set to minimum.Can the pump run without a hose/diffuser?
No. Operating the pump idle leads to premature diaphragm wear and higher noise levels.
