The EHEIM professionel 4+ our best external filter but now with an integrated "emergency" button.
EHEIM have adopted the many advantages of the professional 3 series – powerful performance, optimal energy efficiency, quiet operation, priming aid, safety hose adapter – but we have also improved the technology by incorporating the new "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 main-tained and the service interval can be extended by a few days.
Advantages of the EHEIM professionel 4+ filter
- Premium class external filters with all the advantages of the professionel 3 series
- Additional control function (Xtender) to counteract blocked filter media and extend intervals between cleaning
