Eheim Professionel 4+ 350 External Filter (2273)

High quality filtration technology with integrated features:

The Professionel 4+ is the most advanced generation of Eheim’s Professionel external filter range. The square canister offers stability, a large filter volume, is suitable for corners and doesn’t take up too much space.

Due to the new Xtender function, the intervals between cleaning the filter can be extended.

Professionel 4+ filters are available in three sizes for aquariums up to 250, 350 and 600 litres.

All professionel 4+ filters are characterized by a high flow capacity, low energy consumption and additional features:

Integrated Heating Element*

Both the Professionel 250T and 350T models have an adjustable integrated heating element, so that no in-aquarium heater is necessary.  

Self-priming

No more complicated suction methods! The self-priming aid primes the filter system for a quick and easy start.

Safety hose adapter

Tap unit with 2 hose connectors - for safety reasons, the hose adapter can only be released when the valves are closed.

Prefilter

The top prefilter traps large particles of dirt and can be cleaned regularly, allowing the maintenance period between media cleaning to be extended.

Filter baskets

Individual filter baskets for biological and mechanical media. Baskets can be easily removed, and the contents can be cleaned using the ‘Easy Clean’ grid. Simple to remove and easy to clean.

„Xtender“ Control Function

If the media (fine filter pad) becomes blocked, the flow rate can be increased using the control function. The water will be redirected but the biological filtration will be maintained - allowing the cleaning of the filter to be postponed for a few days.

Quiet operation

EHEIM high performance bearings and ceramic axles guarantee quiet running, long life and durability.

Ready to connect

All professionel filters will include original EHEIM filter media and the following corresponding accessories: inlet and outlet pipes, EHEIM quality hose and set up accessories.

*NOTE: Integrated Heating Element not suitable for use with Saltwater.
