Motorised Debris Screen for Biotec and Screenmatic Filters The Oase Biotec 36 / Biotec Screenmatic 32–38 fabric screen (originally item 28412) is the replaceable mesh that the motorised cleaning system scrapes and brushes continuously to remove leaves, string algae, and coarse debris from incoming pond water. When the fabric wears thin, tears, or stretches, debris passes through to the foam stages and clogs them faster. Extends Foam Life By catching coarse material before it reaches the foam, the fabric screen dramatically reduces how often you need to clean or replace your filter foam. A fresh screen restores this first line of defence and keeps the automated cleaning cycle effective. Check the fabric at the start of each season and replace if you see holes or sagging.
