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 main-tained and the service interval can be extended by a few days.
There are 3 sizes available for aquariums up to 250, 350 and 600 litres. The models 250 and 350 are also available with an integrated heater as thermo filter (T). In addition, the professionel 350e can be electronically controlled from a PC.
High quality filtration technology with integrated features
professionel 4+ is the most advanced generation of our professionel external filters. 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.

- The most advanced model is the high tech professionel 4e+ 350 which can be electronically controlled from a PC (see professionel 3e)
All professionel 4+ filters are characterized by a high flow capacity, low energy consumption and additional features:
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.
The top prefilter traps large particles of dirt and can be cleaned regularly, allowing the maintenance period between media cleaning to be extended.
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.
EHEIM high performance bearings and ceramic axles guarantee quiet running, long life and durability.
