Eheim Professional 4+ 350 External Canister Filter
The EHEIM professionel 4+ – our best external filter but now with an integrated ‘emergency’ button.
We 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 maintained and the service interval can be extended by a few days.
Advantages of the EHEIM professionel 4+ filter include: 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; high performance ceramic axle guarantees quiet running and durability; integrated self priming aid to initially prime the filter; safety hose adapter can only be removed when the valves are closed; top prefilter effectively traps large dirt particles and allows for longer service intervals. Simple to remove and easy to clean; individually filter baskets with "Easy Clean" grid ; and, fully equipped with original EHEIM filter media and installation accessories.
