Description
Modern filters in different models. There are 3 models of the Eheim external filter professionel 4+ for aquariums up to 250, 350 and 600 litres. The models 250 and 350 are also available with integrated heater as thermal filter (T). The 350e model also offers you electronic control from a PC (see professionel 3e).. But the highlight is the new “Xtender”: If the filter masses are dirty and the water flow decreases, simply readjust the knob if necessary. So you do not have to intervene immediately and gain a few days time until the next cleaning of the filter media. The biological filtration (detoxification) is nevertheless maintained by diverted water flow.. In terms of colour, the professionel 4+ appears in a new guise. The filter is in modern anthracite grey and is delivered with matching hoses, tubes, etc… Advantages of the Eheim professionel 4+ filters. – Top-class external filter with all the advantages of the professionel 3 series for aquariums from 120 to 600 litres. – Additionally with control function for extending the service life of dirty filter masses (Xtender). – Square basic shape for large filter volume and high stability. – High flow capacity with very low energy consumption. – Adjustable pump capacity. – Whisper-quiet running and extremely long service life thanks to high-performance ceramics in the pump drive. – Suction aid for fast filling of the filter system. – Safety hose adapter; can only be released when valves are closed. – Large pre-filter retains coarse dirt and ensures long life of biological filter material; easy to remove and easy to clean. – Individually removable, individually fillable filter baskets with “Easy Clean” cleaning grid. – Completely equipped with original Eheim filter media and installation accessories.
