Oase Biopress 4000 Set ( Includes pump UVC and filter)

OASE BioPress 4000 Set: Pressurised Pond Filter with UVC, Pump & Hose Included

The OASE BioPress 4000 Set is a complete, ready-to-install pond filtration kit. You get a compact pressurised filter with a built-in 7W UVC clarifier, plus the pump and hose, all in one box. It keeps ponds of up to 4,000 litres (without fish) clear and healthy.

It's backed by the OASE Clear Water Guarantee, so you can buy with confidence.

Why a pressurised filter?

Unlike open-top box filters, a pressurised filter pushes water out under pressure. That means it can:

• Feed elevated watercourses and small waterfalls above the filter
• Be buried discreetly beside the pond so it's out of sight
• Sit away from the pond edge without needing to be the highest point

Easy cleaning without opening the filter

OASE's patented cleaning system lets you clean the filter sponges quickly and effectively without opening the housing. Less mess, less time and no fiddly seals.
