BioPress Set 4000

Code: 50504

The OASE BioPress Set 4000 is a complete pump and pressure filter system for ponds up to 4,000 litres.

Designed for pump-fed setups, it allows you to return filtered water uphill to a waterfall or raised outlet while keeping the unit compact and easy to hide. Ideal for small ornamental garden ponds.

Original price was: £459.99.Current price is: £229.99.

Product Description

  • To the filter, get set, go: The BioPress Set 4000 is ideal for every start-up pond owner, as the complete set including 4.5 m hose is very easy to install and connect. It is particularly characterised by its effective filter performance, as the 25 watt filter pump, pressure filter and integrated 7 watt UVC pre-clarifier included in the set are perfectly matched. Ponds up to 4 m³ (up to 2 m³ if stocked with fish) are guaranteed clear water, which can even be transported to a higher stream.

    Contaminated water is transported to the filter at a rate of 1500 litres per hour. Its ease of use is impressive, as your hands remain clean when cleaning the filter sponges, which even show how dirty they are on the outside. And so that nobody can see the filter, it can be almost completely buried. Trust in OASE quality: You receive a 2-year guarantee plus a clear water guarantee.
