Pre-filter for Coarse Debris d90/d110

The pre-filter for coarse debris is a device installed upstream of the circulation pump in piping with diameters d90 or d110.

It captures larger mechanical impurities – leaves, insects, hair, or sand – and protects the pump impeller from blockage or abrasive wear.

A transparent or easily removable basket allows visual inspection of the fill level and quick cleaning without tools.

Installing the pre-filter extends the service intervals of the main sand filter and significantly reduces the risk of pump failure during the season.
