EHEIM 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.
