The skimmers of the Classic DOC skimmer model series operate according to the
horizontal rotation principle, supplemented with the newly developed air
production of the Hydrofoamer. Despite its very small structural shape, this
unit has an excellent skimming performance, and is especially suitable for
breeding tanks with living plankton. The immersiondepth ranges from 60 to
90 mm (2.3 to 3.5 in.). They can also be used in aquarium cabinets and tolerate
water level variations of +/- 20 mm (.78 in.) without readjustment of the air
output.
Principle: In 1963, TUNZE® developed the first series-produced protein skimmer
with its own air production. In this rotating Venturi skimmer, the hard water
jet of a pressure pump is used to produce a constant fine mixture of air bubbles,
which is passed into an easy-to-clean skimmer cup by means of an effective
removal system. An integrated contact pipe is used to remove protein particles
from the water. The refill from the aquarium then is drawn in automatically by
means of the so-called molecular compensation pressures (diffusions).
