Eheim Air compressor 400l/h (3704)
Power output is extremely quiet and is adjustable in all three models: once in the smallest model of the series, twice in the medium-sized and large air pump. Thus both air outlets can be adjusted separately in the larger models.
All 3 models are supplied fully equipped. That means: Air hose and EHEIM outflow unit(s) included. The 200 l and 400 l models are delivered with 2 outflow units and the 100 l air pump comes with 1 outflow unit.
The supplied EHEIM outflow unit is also adjustable. Thus the bubbling pattern can be easily adjusted to your taste and the requirements of your aquarium.
