Product Description

The EHEIM Professionel 4+ is an evolution of the Professional 3 range of external filters, featuring a new ‘emergency’ button.

Eheim have engineered many advantages when compared to the Professional 3 series – powerful performance, optimal energy efficiency, quiet operation, priming aid, safety hose adapter – and also an improved new technology with the incorporating of the ‘Xtender’ button.

In the event the output is reduced due to the fine filter media blocking, the button can be adjusted to redirect the flow. The biological filtration is maintained and the service interval can be extended by a few days. Includes a integrated heater.
