The EHEIM air pump is
equipped with an eye for wall fastening but can also be safely mounted on
the vibration resisting rubber edges in a traditional manner. This prevents
the filter from “moving around“. 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. 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.
