Eheim - 2274 Professionel 4e+ 350, Внешний фильтр с наполнителями

The EHEIM professionel 4e+ our best external filter but now with an integrated "emergency" button.

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.

The large number of new functions can be easily operated using just 3 buttons.

	Output control Stepped increase or decrease of the water flow at the push of a button. The maximum power of this model greatly exceeds the values for conventional filters.
	Constant flow The electronics automatically recognizes an increasing filter pollution and re-adjusts the flowrate to the value set by you. This guarantees constant flowrate values over a long period until a pollution degree is reached which can no longer be compensated by the electronics.
	Stream function The electronically controlled alternating stream assures near-natural stream conditions in the aquarium.
	12h bio function Electronic alternation between two settable flowrates in a 12-hour rhythm.
	Service indicator Upon pushing the button, the device shows the remaining period to the next cleaning. 1 green LED = 1 month
	Auto air out The system detects trapped air beneath the filter head and automatically bleeds the air off via an electronic program.
	Electronic error management The system constantly monitors itself, recognizes irregularities and indicates them in the form of warning signals. At the same time, a program automatically attempts to rectify the respective causes.
	Auto calibration To guarantee maximum control accuracy, the system permanently checks and at least once a day calibrates itself. For this procedure, the pump delivers a pre-set (high) flowrate and indicates this via a green sequentially illuminated light.
	Manual mode The MANUAL MODE function is used to deactivate automatic readjustments and the service function.
	Reset function The RESET FUNCTION is used to reset all the functions to the factory settings.
	OPTIONAL: USB connection With the USB converter the EHEIM professionel 3e/4e+ external filter can be connected to a computer via a USB interface (NOT INCLUDED! Order no. 4020740). The functions can be conveniently controlled and monitored using the free and user-friendly software EHEIM ControlCenter. More detailed information is available at: www.eheim.com
