EHEIM PROFESSIONEL 4+ 350 – Premium External Filter with Xtender Function for Aquariums up to 350 Liters
The EHEIM Professionel 4+ 350 is an advanced external filter designed to deliver superior performance, energy efficiency, and durability for both freshwater and marine aquariums. As an evolution of the acclaimed Professionel 3 series, this model introduces significant enhancements for quieter operation, increased power, and easier maintenance. It’s ideal for tanks ranging from 180 to 350 liters.
Equipped with a 5-liter filtration volume, a 7.4-liter media basket, and a 0.5-liter pre-filter, the 4+ 350 offers layered mechanical and biological filtration that ensures crystal-clear water and a stable aquatic environment. With a flow rate of 1050 L/h and a maximum head height of 1.8 meters, it handles heavy bioloads efficiently—while consuming only 16 watts of power.
The standout feature is the Xtender function, which allows users to reroute the water flow in case of partial clogging, extending maintenance intervals without disrupting the biological filtration process.
Its square-shaped media basket offers enhanced stability and capacity. Additional features include a built-in self-priming system for quick start-up, a secure hose adapter system, and an easy-access top-mounted prefilter that captures larger debris before it reaches the finer media.
The filter comes fully equipped with original EHEIM filter media, hoses, connectors, and accessories for immediate setup and operation.
