Wine Filter Sheets 20 × 20 cm for Plate Filters

Wine filter sheets 20 × 20 cm, also commonly referred to as filter pads, are supplied in packs of 25 pieces.

They are made in Italy according to high quality criteria and current regulatory standards. These depth filter sheets are designed to optimise depth filtration performance, providing substantial improvements over surface filtration.

Filter sheets are widely used in the food, chemical and pharmaceutical industries thanks to their retention characteristics and filtration quality.

They can be used for roughing, polishing and removing particles and microorganisms present in liquids.

This specific type of filter sheet for plate filters with pump, such as Rover filters, is available in different grades for wine filtration. Depending on the selected grade, the sheets can be used for young or cloudy wines, clarification, polishing or sterilising filtration.
