Eheim 2271 Professionel 4+ 250 External Filter

Description

Professional 4+ 250 External Filter from Eheim

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 ‘Extender’ 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-tainted and the service interval can be extended by a few days.

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.
“Extender” 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 professional filters will include original EHEIM filter media and the follow-ing corresponding accessories: inlet and outlet pipes, EHEIM quality hose and set up accessories.
