Eheim Professional 4+ 250T Aquarium Canister Filter represents high quality, strong performance, excellent power efficiency & smooth operation and now with the new Xtender function.

The Eheim Professional 4+ boasts a square base for stability, a very large filter volume, and easily fits tightly into corners. In the event the flow output is reduced due to the fine filter media blocking, the new Xtender button can be adjusted to redirect the flow. The biological filtration is maintained and the service interval can be extended by a few days. No more complicated suction methods with the self-priming Eheim suction aid, the filter canister is quickly filled and immediately ready to start. The unique safety hose adapter can only be released when the hose valves are closed. A large prefilter, positioned at the top of the canister, retains coarse dirt and can be cleaned quickly between maintenance intervals. This protects the biological filter material in the other 3 filter baskets, providing a much longer service life. The other filter baskets can be filled individually and are easily removed for cleaning. Eheim high-performance ceramic components used in the impeller axles and bearings mean exceptionally quiet operation, high load capacity, and extremely long service life.

 

Eheim Professional 4+ series filters are available in a choice of 3 models, 250, 350 & 600 with the 250 & 350 having the additional twin sister option of Thermo Filters (T) heated models. The Eheim Professional 4+ series is suited for aquariums with volumes from 120 to 600 Ltrs.
