Tunze Classic DOC 9211 Protein Skimmer

Tunze Clasic DOC 9211 Protein Skimmer.

The skimmers of the Classic DOC skimmer model series operate according to the horizontal rotation principle of the first generation, supplemented with the newly developed e-jet Hydrofoamer. Despite its very small structural size, this unit has an excellent skimming performance, and is especially suitable for breeding tanks with living plankton. Classic DOC skimmers can be placed easily and inconspicuously in the aquarium at an immersion depth of between 60 and 90 mm (2.3 and 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. Skimmer cup and foam reactor are one unit in all TUNZE® Classic DOC skimmers. Delivery condition: Completely ready for mounting with holding device for vertical panes and horizontal glass tops up to 19 mm (.74 in.).

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 collected in 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 protein from the aquarium then is drawn in automatically by means of the so-called molecular compensation pressures (diffusions). This TUNZE® invention of contact skimming makes sure that no living plankton is drawn into the pump circulation.
